Internet-based outbound calling software, also known as VoIP (Voice over Internet Protocol) calling software, allows users to make phone calls over the internet rather than traditional phone lines. It utilizes the power of the internet to transmit voice data in digital format, enabling cost-effective and efficient communication.
Here's a breakdown of how internet-based outbound calling software works:
Voice Data Conversion: When you speak into a microphone or use a headset, the software converts your voice into digital data. This data is then packaged into small packets for transmission.
Internet Transmission: The digital voice packets are sent over the internet using the IP (Internet Protocol) network. They travel through various routers and network switches until they reach the recipient.
Destination Identification: The software determines the recipient's phone number or IP address to establish a connection. This can be either a traditional phone number or another device connected to the internet.
Call Routing: The software finds the most efficient route to transmit the voice packets to the recipient. It may use specialized routing algorithms to optimize the quality and reliability of the call.
Voice Playback: Once the voice packets reach the recipient, the software on their end reassembles the packets and converts the digital data back into an audible voice. This audio is then played through the recipient's speakers or headset.
Call Control Features: Internet-based outbound calling software often includes additional features such as call recording, call forwarding, voicemail, call analytics, and integration with other communication tools like CRM (Customer Relationship Management) systems.
Integration with Hardware: Internet-based calling software can work with various devices, including desktop computers, laptops, smartphones, and even dedicated IP phones. It may require specific software applications or web-based interfaces to make and receive calls.
Service Providers: There are numerous service providers that offer internet-based outbound calling software. They provide the infrastructure and support necessary for making and receiving calls over the internet. Some popular examples include Skype, Zoom, Google Voice, and many business-oriented VoIP providers.
Benefits of Internet-based Outbound Calling Software:
Cost savings: VoIP calling software often offers lower rates for long-distance and international calls compared to traditional phone services.Flexibility and mobility: As long as you have an internet connection, you can make calls from anywhere using your preferred device.Feature-rich: VoIP calling software usually comes with advanced features like call routing, call recording, voicemail, and integration with other applications.Scalability: Internet-based calling systems can easily accommodate a growing number of users without requiring significant infrastructure upgrades.Integration: They can integrate with other communication tools, customer databases, and software systems, enhancing productivity and workflow efficiency.Overall, internet-based outbound calling software leverages the internet's capabilities to provide a cost-effective, flexible, and feature-rich solution for making phone calls. It has become a popular choice for individuals and businesses seeking efficient communication alternatives to traditional phone services.

The main point of this lecture is to encourage critical thinking. So much of what “everyone knows” about network protocols is, actually false. For instance, why do we need both Ethernet and IP? The “obvious” answer is that IP is “layer 3” and Ethernet is “layer 2”, but in fact, once Ethernet stopped being a single wire (layer 2), and something that is forwarded (layer 3’s job) it became a layer 3 protocol. So the right question is “why do we use to layer 3 protocols?” The answer is subtle and leads to discussion of how Ethernet became a “layer 3” protocol, and evolution to TRILL and other overlay networks. There are also buzzwords such as “SDN”, and fads such as “active networks” and “information-centric networking”. This talk will demystify these, as time follows.

5G promises a supercharged future. Data connectivity will be near instantaneous. But, as seen below, there’ll be some bumps, bruises and tradeoffs along on the way.
Via Eric Niiler, WIRED
IF YOU HAD a choice between a better, faster cell phone signal and an accurate weather forecast, which would you pick? That’s the question facing federal officials as they decide whether to auction off more of the wireless spectrum or heed meteorologists who say that such a move could throw US weather forecasting into chaos.
On Capitol Hill Thursday, NOAA’s acting chief, Neil Jacobs, said that interference from 5G wireless phones could reduce the accuracy of forecasts by 30 percent. That’s equivalent, he said, to the quality of weather predictions four decades ago. “If you look back in time to see when our forecast scale was roughly 30 percent less than today, it was 1980,” Jacobs told the House Subcommittee on the Environment.
That reduction would give coastal residents two or three fewer days to prepare for a hurricane, and it could lead to incorrect predictions of the storms’ final path to land, Jacobs said.


What Factors Can Influence VPN Speed?
The speed of a VPN is an important thing to take into consideration. For many people, this will be the determining factor for whether or not they decide to use a VPN at all. This is especially true when it comes to the internet - in reality, speed does matter. Even if the service improves online security and can help get around blocked content; if it's slow overall experience will be anything but ideal!
The speed of a VPN can be affected by various factors, which is what I will discuss in this article.
1. VPN Protocols
There are many different protocols that can be used to establish a VPN connection. Some of the more popular ones include OpenVPN (over UDP or TCP), SSTP, PPTP and L2TP/IPSec. Everything else being equal, each protocol results in a significantly different speed for your VPN connection. For example, using OpenVPN over UDP typically yields faster speeds than with it over TCP.
UDP is a good default protocol to start with when using OpenVPN. If you're having speed issues, try switching to another protocol and see if your VPN speed improves.
2. VPN Server Location
The closer to your location a VPN server is, the more you will experience speed. This is because the complexity of Internet traffic increases as distance between you and the VPN server increases. The greater this complexity and distances data has to travel, slower your connection becomes.
When you don't have a reason to connect to a particular VPN location, choosing the one closest is best. For example, if you live in Texas and want access to US servers, use one that's located in Houston or Dallas instead of New York. Similarly, if you're using a VPN in China or using a VPN in Japan and need access through an American server, find one on the West Coast over somewhere east coast-based.
3. Encryption Level
Stronger encryption is often more of a time-consuming process and can, as a result, slow down the VPN connection. A 128-bit encryption will in most cases lead to faster internet speed than if you have 256 bit.
On the downside, lowering the levels of encryption make your data less secure and transmitted information more vulnerable to being intercepted by hackers or from third parties who might be accessing what you are sending across your network. So if you're going for anything lower than 128 bit I would recommend testing it out first before relying on it heavily since some devices might show significant improvements with weaker encryptions but not all do so feel free to experiment around too!
4. Network Setup
It is worth noting that the speed of a VPN connection can be influenced by which network your device is connected to. If you have an internet connection from either a wired network or WiFi, it might affect how fast connections are completed when using VPNs. Whether you share a VPN connection with other people or using hardware like Ethernet cables on networks will often yield faster speeds than using WiFi for this purpose - in-depth research should be done before making assumptions about the quality and speed of your wireless connections!
5. Performance of VPN Server
The power of a VPN server will have a significant impact on the speed. If it is overloaded with bandwidth that cannot keep up with demand, there will be slower performance. The client software you use to connect to your VPN service should tell you how many IP addresses and how much bandwidth each sever has in real-time. Higher numbers mean more powerful servers; switching between them is usually as easy as choosing from different tabs on your screen.
In the end, not all VPN providers are created equal. This is because even when ideal conditions do exist, amongst various other reasons for this disparity in performance, their speed and reliability may be drastically different too. If you have tried implementing several of the methods mentioned but are still unable to see an improvement in speeds then it may be time to consider switching VPN providers instead.

Information » Your World » Living Abroad » Communications
If you are considering living abroad, it is important you stay in touch with family and friends you leave behind so they know you are safe.
There are many ways to keep in contact with your family and friends including by post, by email, social networks or by phone.
Using a phone abroad
- Calling from a mobile phone abroad can be expensive, and it might be worth taking out a contract with a new phone company abroad
- Alternatively, you may want to keep your existing mobile phone and call your operator to make sure you can use it in other countries. The charges can vary depending on your operator and which country you are in. Make sure you find out the charges first
- Even though a simple text message can tell people that you are safe, its better to speak to loved ones from time to time to let them know how you are doing
- Some countries will not have mobile phone coverage. It's best to find this out before you leave
- If you do not want to use a mobile phone abroad, you can use a pay phone which can work out cheaper
- If you are using a land line you can buy a calling card which is a cheaper way to make calls
- Emailing is a quick and easy way of staying in touch with people
- Provided you have internet access, using email is a great way to contact your family and friends. You can also send digital photos attached to your emails
- Most mobile phones now have WAP which allows you to send emails using your phone. Make sure you check charges before you send messages
- Instant messaging is becoming an increasingly popular method of 'chatting' over the internet and is quicker than email
- It allows you to see who you know is logged on to the internet and send them instant messages
- Instant message users create 'buddy lists' of their friends who they can send messages to. The 'buddy list' indicates who is online
Voice calls over the internet
- Talking over the internet is like using a phone - you can make calls to people all over the world but at a much cheaper rate than a telephone call or mobile phone call
- Some companies who offer this service will charge a monthly fee and some will charge by the minute and some are completely free of charge!
- To set up this facility on your computer you will need to download a programme and use a headset.


India on Wednesday successfully launched the advanced earth observation satellite Resourcesat-2, a move aimed at beefing up its remote sensing capability, and two smaller satellites on the PSLV rocket from its spaceport here.
On a bright morning around 10.15 a.m., the Indian Space Research Organisation’s Rs.90 crore rocket – the Polar Satellite Launch Vehicle (PSLV) – soared towards the heavens to place in orbit Resourcesat-2.
Built to last for five years, the Rs.140 crore crore Resourcesat-2 will augment ISRO’s remote sensing data services. It will replace Resourcesat-1 sent up in 2003.
Resourcesat-2 was originally scheduled for a January launch but got postponed to February and then to April.
Apart from carrying three sophisticated cameras, the satellite also carries additional equipment called AIS (Automatic Information System) from COMDEV, Canada, for the surveillance of ships in the VHF band to derive their position and speed, among others.
"With the launch of Resourcesat-2, ISRO will have 10 remote sensing satellites in orbit- Resourcesat 1, TES, Cartosat 1, 2, 2A and 2B, IMS-1, RISAT-2, Oceansat-2," S. Satish, ISRO’s director (Publications and Public Relations), told IANS.
With the largest civilian remote sensing satellite constellation in the world, India is a global leader earning a sizeable amount vending imageries in a variety of spatial resolutions, spectral bands and swaths.(IANS)


FireWire IEEE 1394 a / b
FireWire, also known as i.Link or IEEE 1394, is a serial bus system developed by Apple as successor of the SCSII bus. The brand name FireWire, to be found only on Macintosh computers by Apple for a long time, became popular only after the introduction of the i.Link interface by Sony as part of the IEEE 1394a standard for consumer products, such as camcorders. This 1394a standard, introduced in 2000, allows for a fast data exchange between computer and multimedia or other peripheral devices. FireWire now competes with the widely used USB 2.0 bus, however, it had a data rate of 400 Mbit/s already years before.
Advantages of FireWire IEEE 1394 a/b over other analogue systems
Advantages of FireWire IEEE 1394 a/b over other analogue systems
- The digital image transmission provides a loss-free signal transfer and therefore a better image than analogue image transfer.
- Omission of the expensive frame grabber card. Many PCs already provide an integrated FireWire interface. (Nevertheless it is recommendable for machine vision to use an IEEE 1394 PCI card which, however, is cheap compared to a frame grabber.)
- Cheap standardised cable and plug technology. Even high-quality robust FireWire cables with lockable plus are clearly cheaper than analogue Hirose cables (simple analogue coaxial cables aside...).
- Hot plug, peer-to-peer communication, integrated voltage supply in the cable provide for a sophisticated operation even of several cameras on the bus.
Characteristics of FireWire 400 - IEEE 1394
- Transmission bandwidth of 100, 200 or 400 Mbit/s (12, 25 or 50 megabytes per second gross); therefore image data of approximately 38 MB per second net can be transported in camera operation.
- The technology offers hot plug / hot unplug: devices can be connected and detected during operation.
- Integrated voltage supply (8 to 33 VDC, 1.5 A, max. 48 W) for devices in the 6-pole cable. FireWire 400 uses a 6-pole cable, four data lines and two lines for bus voltage. The 4-pole variant ("i.Link" by Sony) provides no voltage supply and is therefore not used for industrial machine vision cameras.
- The thin flexible 6-pole cables are shielded twisted pairs (STP), quite interference-free, have a thin cross-section and can easily be laid in an industrial environment.
- Data transmission is possible in both directions: camera control, triggering, parameterisation is equally possible during operation.
- Officially specified are 4.5 m maximum distance between two devices (at 400 Mbit/s), yet up to a 10 m can be realised in practice. If the speed is limited to 200 Mbit/s, a maximum of 14 m can be bridged. The maximum transmission length strongly depends on the quality of the integrated bus components in camera and PC and the quality of the cable.
- Longer distances require inline repeaters or FireWire hubs which are connected in between.
- In theory, up to 63 devices can operated on one bus, 16 of which can be cameras. The term "daisy chain" refers to a wiring pattern in which one device is connected to the following one; i.e. A to B, B to C, C to D. IEEE 1394 devices usually have two connection in order that the mentioned chaining can be realised. Cable lengths can be maximised in this way.
- Practical experience with IEEE camera systems in industrial facilities, however, reveals that up to 3 cameras on one bus always work in a stable and reasonable manner, yet interferences, problems with the overall cable length, etc. occur beyond that. Therefore use rather one or several dual FireWire cards if you want to operate more cameras, particularly synchronously and with high load.
Characteristics of FireWire 800 - IEEE 1394b
- A different signal coding and signal level serves to achieve a transmission bandwidth of 800 Mbit/s (100 megabytes per second); therefore image data of approximately 75 MB per second net can be transported in camera operation.
- The cable has been changed, now it has nine conductors and a new plug, but a backwards compatibility to 1394a was made possible using bilingual controller chips. A FireWire 1394b interface can operate FireWire 1394a devices, too, using suitable adapter cables.
- FireWire 1394b allows for the use of different cable materials, e.g. fibreglass. Therefore cable lengths of up to 100 m are no longer a problem. Modern camera suppliers offer appropriate cameras which cannot only connect copper cables but also fibre optic cables.
The successor IEEE 1394b is much faster than USB 2.0 (approx. 40 MB/s net), having an effective net image transmission bandwidth of approximately 75 MB/s.
The DCAM standard and IIDC
DCAM stands for "1394-based Digital Camera Specification" and specifies the behaviour of 1394-devices with uncompressed image data transmission (without audio). The DCAM standard is only supported by devices which provide a FireWire (IEEE 1394) interface. The responsible working group is the IIDC (Instrumentation and Industrial Control Working Group), thus the standard is called IIDC in newer specifications. Usually these are FireWire cameras with industrial features which are used for inspection applications, for instance. The DCAM standard also defines the standard resolution and image refresh rates of the cameras in different formats. A special role for industrial cameras, however, plays "format 7" which allows for random resolutions and frame rates.
It does not only define the structure of the image data stream generated by the camera, but also the basic parameterisation of the camera (e.g. exposure time, gain, white balance, etc.) and how the camera is to be parameterised.
The PC must support DCAM in order to communicate with a DCAM camera. For this purpose the operating system requires a DCAM driver which is already included in Windows 2000, XP and Vista. However it only supports the most important camera parameters.
Special drivers supplied by the individual camera manufacturers provide a remedy, who are of course interested in setting themselves apart from their competitors by means of special camera features (LUT, shading correction, special trigger modes, etc.). Only by using these drivers the full range of functions and performance of the hardware can be used, yet from this moment on, the camera system is proprietary and bound to one particular manufacturer. The Gigabit Ethernet / GenICam standard can provide a solution.
Neue Kameramodelle werden nicht mehr für diese Schnittstelle entwickelt, Kameras mit GigE Vision oder USB3 Vision Interface ersetzen zunehmend diese Geräte. Conclusion:
Camera families on the basis of FireWire a/b are available today which cover almost all fields of application from 0.3 to 16 megapixels, monochrome or colour, CCD or CMOS. Unfortunately, despite the DCAM/IIDC standard, cameras of different manufacturers are not really 100% plug&play-compatible, special features are only mapped in manufacturer-specific drivers. Without the use of fibre optic transmission, the cable lengths are limited, too.
New camera models are no longer being developed for this interface, cameras with GigE Vision or USB3.x Vision interface are increasingly replacing these devices.


I try to use DSI model to do tractography. However, it seems that MRtrix3 does provide this method, so I turn to use DSI studio software to get the fiber track. And the output of DSI studio is in .trk format. Then I use the code provided by Marc Côté on Github to convert .trk to .tck. But the position of the fiber is wrong which is shown in figure below. Could you please give me any advice?


Voiceitt has introduced the new spontaneous web app- here you can read about what it does, who is it for, and see frequent answers and questions.
What is the new spontaneous speech web app?
The dictated text can then be read out loud by a synthetic voice, and it also can be copied and pasted somewhere else.
so it can be used to dictate emails, social media posts, writing your stories or thoughts, or just to communicate with others who do not understand your speech.
As opposed to the Voiceitt iOS app, it is able to understand spontaneous speech and will be available on the web, so will be accessible from a computer\ smartphone.
Who is the ideal Voiceitt web app user?
The Voiceitt web app supports users with non-standard speech. This means Voiceitt can be used by individuals with various diagnoses that may impact their speech. Some of those diagnoses are Cerebral Palsy (CP), Downs Syndrome, autism spectrum disorders (ASD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), muscular dystrophy (MD), Huntington's disease (HD), deaf or hard of hearing and more.
In a nutshell, the web app is best suited for:
- Individuals who find that standard speech-recognition software does not always understand them due to their speech impairment.
- Individuals with impaired speech who are generally understood by familiar listeners but less understood by unfamiliar listeners.
- Individuals with intact language who say what they intend to and speak in full sentences.
- Individuals who are interested in using speech recognition technology for communication.
- English speakers
Before accessing the web app, we will have to listen to a few recordings to be sure you are a good fit. You can read more about this here.
What does the Voiceitt web app do?
The Voiceitt web app is a speech-to-text augmentative and alternative communication (AAC) software that allows people with speech impairments to use their voice for communication. This system was built to understand non-standard speakers, such as those with motor-speech disabilities, and "translate" their speech to text and automated voice output. It listens to what you say, then writes it down on the screen and can play it aloud. The dictated text can be copied and pasted somewhere else, so you can dictate your emails, social media posts, private messages, etc.
What can the new web app understand?
The new web app is built to understand free and spontaneous non-standard speech even if what you are saying was not pre-trained.
Note: the recognition might be partially accurate at first, but the more you use and train it, the more accurate it becomes. We constantly work to improve our technology and welcome your comments and feedback. Please reach us at email@example.com.
What devices will the new web app work on?
The web app opens on any device connected to the internet and can open a web browser.
Do I need internet access?
Yes. The Voiceitt web app works on the web, so internet access is required.
Do I need to train the Voiceitt web app?
Yes, a minimum of 400 phrases must be trained because every person has a unique speech pattern and voice. The system needs to be customized for every new user. The training is used to create a voice model for every user. You can read more about training here
How long does it take to create my voice model?
Please allow two weeks for Voiceitt to build your custom recognition model. You can always follow up on the progress by contacting us at firstname.lastname@example.org.
How much does it cost?
For beta testers who have recorded a minimum of 1000 phrases, up until August 2023, will get free access for a year- until August 2024.
For the current subscription plans please contact us at email@example.com
Can I listen to or copy the dictated text?
Yes. There is an option for every sentence to play aloud automatically after you say it. Once you have finished dictating your thoughts, there is an option to play the entire text aloud by clicking "play all." You may also copy the text and paste it to an email or word processing software.
What is the difference between the web app and the Voiceitt iOS app?
* While the Voiceitt iOS app can only understand pre-defined and trained phrases, the new web app is designed to understand spontaneous conversation and to understand phrases that were not pre-trained.
* While the Voiceitt iOS app can connect to Amazon Alexa and allows you to control your smart home, the web app is for communicating your thoughts. It does not
It does not connect to Alexa or any other smart assistant however, it can still be used to control smart home assistants through the traditional route of web app speaker output to your smart assistant microphone input.
We recommend using the iOS app for controlling smart home- devices.
The Voiceitt iOS app and web app are two different products. An individual can use both technologies without interference from each other.
How many users can be registered under one email account?
One! Since the Voiceitt web app is custom-built for each individual, everyone who wishes to experience this technology must create and use their own email account.

Sinbad made it!
Finally, Sinbad arrived in its wintering area, Madagascar! The bird arrived on 18 December on the edge of the high plateau of Madagascar and has been staying there at an altitude of 700-1000m since. Unfortunately we did not receive signals during the crossing of the Mozambique Channel. All we know is that the bird was still on African mainland on 16 December.
I am a little anxious that the transmitter fitted to Sheba might have given up sending signals because it has been 10 days since the transmitter was last located by the satellite. We need to wait now to see if there are new signals in the coming days. At the moment we can still be optimistic because the lack of signals can be due to numerous causes (e.g., bad weather, the bird roosting in the shade all day, battery power low, etc.).


Getting your voice back following illness or injury can be a meaningful step in the road to recovery. Visi Pitch is state-of-the-art software that our speech therapists
use to help patients find their voice once again.
How does Visi Pitch work?
Working with a speech therapist
, patients speak into a microphone connected to a computer. The Visi Pitch software records the voice and provides visual and auditory feedback in real time. Therapists can then provide target vocalizations for comparison and the patient works to match these to reach their goal.
The Visi Pitch can help patients recovering from a wide range of illness and injury including:
- Vocal cord injury
- Motor speech disorders


Amateur Radio is not only a grand and glorious hobby, Radio Amateurs serve people through providing emergency communication systems; especially in natural disasters or in other emergencies as a voluntary, noncommercial communication service. Amateur Radio experimentation is yet another reason many people become part of this self-disciplined group of trained operators, technicians and electronics experts are the assets to a country. Hams pursue their hobby purely for personal enrichment in technical and operating proficiency, without any consideration for payments. Below are some examples.
1. During any natural disaster, Amateur Radio operators set up and operate organized local and long-distance communication, as backup of the Government and emergency official communication system, as well as non-commercial communication for private citizens affected from the disasters. Amateur Radio operators are most likely to be active after disasters that damage regular lines of communication due to power outages and/or destruction of the telephone infrastructure.
2. Talk around the world – With HF radios hams can talk to other hams in literally any part of the globe. They can talk from the top of the mountain to deep sea.
3. Talk around town – With small portable VHF and UHF transceivers hams enjoy extremely reliable communications within their local community. They can talk with a minimum range of 20 Kilo Meters up to 500 Kilo Meters by using multiple repeaters.
4. QRP – Communicating with “very low power” is a challenge that many hams enjoy. QRP is usually practiced on the HF bands.
5. Packet Radio – The internet over ham radio? Not really … but ham radio operators enjoy a digital network of their own, all without wires!
6. Amateur Television – It’s just like real television because it is real television. Slow Scan TV Send pictures around the world for little or no cost.
7. Contests – They can put their radio operating skills up against other hams and teams of hams.
8. Hopefully they will use their radio less for calling the fireman, the police, and emergency road-side assistance, 911 and other telephone-linked services.
9. Emergency and other volunteer services – Floods, hurricanes, mudslides, earthquakes, ice storms … when ever normal communications go out, hams are ready to use their radios to provide emergency communication services to their communities.
10. Satellite Communications – Hams have their own satellites. Amateur’s satellites are easy to Use. Even Hams can talk with the astronauts of ISS (International Space Station or Alpha Station) and they used to talk with MIR station on the space.
11. Emergency Traffic Handling – “Ham Telegrams” are used to send messages to people around the world at no cost to the sender or the recipient; all done by ham radio operators Volunteering their time and resources.
12. Emergency Medical Support – Ham Medical Team formed with some Doctors who are HAM. This kind of team work on any natural disaster and urban incident.
This unique mixture of fun, convenience and public service is the distinguishing characteristics of Amateur Radio. Although people get involved in amateur radio for many reasons, they all in common have the basic knowledge of radio technologies, regulations and operating principles, which is demonstrated through passing an examination leading to a certificate of proficiency. And through getting an authorization to operate on radio frequencies known as the “Amateur Bands.” Radio amateur reserve these bands for use at intervals from just above the AM broadcast band all the way up into high microwave frequencies.
Hams exchange pictures of each other using television. Some also like to work on electronic circuits, build their own radios and Antennas. Anyone above the age of 12, no matter gender or Physical ability and educational qualification can become a Ham.

You’ve probably heard some buzz about 5G, the next generation of cellular network technology. But what exactly is 5G and how will it impact healthcare?
5G: the basics
The G in 5g means it’s a new generation of wireless technology. We had 1G, 2G, 3G, and 4G networks before this. While most generations have technically been defined by their data transmission speeds, each has also been marked by a break in encoding methods, meaning each is incompatible with the previous generation.
5G brings three new aspects: bigger channels (to speed up data transfer), low latency (faster responses), and the ability to connect a lot more devices (for sensors and smart devices).
All US carriers have now launched some form of 5G cellular network. But their advertising belies what will actually be a slow transition. Most locations and devices still use 4G, and that network will be around for a long time. However, in the coming years you can expect to see more and more use of 5G networks with some exciting developments for healthcare.
How will 5G impact healthcare?
The impacts of 5G in healthcare range from the fairly simple to the futuristic. Here are a few examples of how healthcare will benefit from faster data transfer, lower latency, and more connected devices.
1. Telehealth will get easier
The transition to telehealth has sped up dramatically in response to the COVID-19 pandemic. As 5G becomes mainstream, you can expect a quick, clear connection and easy videoconferencing nearly anywhere.
2. The Internet of Things will grow
In healthcare, the Internet of Things (IoT) describes a growing network of medical devices and software applications connected through health care technology systems. 5G will make it easier to transfer data quickly from many connected devices, making key IoT functions like remote patient monitoring more widely available.
3. Data will transfer faster
We’re in an era when the amount of health care data is growing at rates never seen before. Whether you’re doing research from huge data pools or just trying to send an X-Ray or MRI, 5G will make data transfer faster. In fact, the technology allows for a theoretical maximum speed that is 100 times faster than it’s 4G predecessor.
4. We’ll see more augmented reality applications
Faster data transfer and device response times will gradually allow for a whole new host of applications. In medicine, this means we can expect to see expanded use of augmented and virtual reality tools for complex medical training scenarios.
5. Surgeries may be done remotely
There’s a whole list of futuristic applications that 5G is likely to enable. One example is 5G’s potential to power robotic surgery tools that eliminate lag time between doctors and patients at a distance. The first effort of this type actually took place in China last year, when 5G aided a surgeon to robotically place a brain stimulation device in a patient with Parkinson’s disease located 1,900 miles away.
The transition will be gradual
The transition to 5G has started but it is far from over. In healthcare, it may take a decade to fully see the benefits of this new network.
Even though 5G is currently available, access to the network is limited. Most smartphones currently in use aren’t compatible with 5G and coverage-wise 5G only exists in a few metro areas. Even where 5G is available, it isn’t always accessible in a consumer-facing capacity. There have also been concerns about misleading 5G branding and worries about 5G cell towers’ short range.
For healthcare, transitioning to 5G will require new devices and infrastructure. “It needs to be done in a methodical way,” Craig Richardville, CIO of SCL Health in Denver recently told TechTarget. “That includes upgrading technology and applications to either speak 5G or disabling the legacy technology piece by piece.”
It will take time for 5G to become a mainstream component of healthcare. But as physicians and industry leaders, it’s important that we start planning and problem-solving now.


We considered the interaction of semiconductor quantum register with noisy environment leading to various types of qubit errors. We analysed both phase and amplitude decays during the process of electron-phonon interaction. The performance of quantum error correction codes (QECC) which will be inevitably used in full-scale quantum information processors was studied in realistic conditions in semiconductor nanostructures. As a hardware basis for quantum bit we chose the quantum spatial states of single electron in semiconductor coupled double quantum dot system. The modified 5- and 9-qubit quantum error correction (QEC) algorithms by Shor and DiVincenzo without error syndrome extraction were applied to quantum register. 5-qubit error correction procedures were implemented for SI charge double dot qubits in the presence of acoustic phonon environment. Chi-matrix, Choi-Jamiolkowski state and measure of decoherence techniques were used to quantify qubit faulttolerance. Our results showed that the introduction of above quantum error correction techniques at small phonon noise levels provided quadratic improvement of output error rates. The efficiency of 5-qubits quantum error correction algorithm in semiconductor quantum information processors was demonstrated.

There are two set s of terminals on Forsmans speakers, also known as bi-wiring.
It is required that two sets of speaker cables are connected to the same point on the amplifier each again connected to the speperate terminals on the speakers.
This is done to reduce the distortion which is caused by the loss of voltage over the cables used. Bass and midtone/treble uses approximately equal amounts of power. When you play loud music this will lead to loss of voltage over the cable in accordance with the increase of the volume of the music.The loss of voltage causes adjustments of the volume between the elements so that the speaker will modulate inaccurately. The solution is to have seperate leads for bass and midtone/treble which will not be influenced by the loss of voltage on the other cable. It does not help to connect/bridge the terminals on the speaker itself.
The terminals are placed at the bottom of the speaker so that the cable connection is hidden and does not protrude as a sore thumb. This is an awardwinning loudspeaker we are talking about here.

This project used the Unity Low-Level API for UDP socket communication between 5 touch-screen controlled client machines and a single ‘server’ hub machine. The server ran a 3D game containing 5 lego tracks each with train controlled by one of the client machines. State machine implementations on both server and client together with a simple API allowed efficient bi-directional communication between server and client.
High quality 3D assets were supplied by LEGO and optimised for display in Unity. Control of the trains was achieved using the Tracks and Rails plugin to provide realistic physics properties for the rolling stock. Carriages were connected by a system of joints and springs to the engine. In April 2016 I travelled to Tokyo to complete the installation working alongside staff at the discovery centre. The new exhibit was launched with a fanfare and local TV coverage.

NEW ELECTR0NICS FOR THE 3M MASTER TAPE RECORDER
NEW ELECTR0NICS FOR THE 3M MASTER TAPE RECORDER
C. Dale Manquen
Revere-Mincom Division 3M Company
Presented at the 33rd AES Convention in New York City October 1967
In 1964 the 3M Company introduced the 3M Brand Professional Recorder, a state-of-the-art audio-range tape recorder that featured a closed-loop tape drive and solid state Dynatrack electronics. The low wow and flutter of the transport and the extended dynamic range of the electronics created a favorable demand for the machine in the professional market. Because of this, a decision was made to revise the machine to make it suitable for production in large quantities. The second generation version was introduced in 1965. The major changes were the use of a precision machined aluminum casting in the transport and the addition of compatible NAB electronics. This new machine proved to be very versatile, but the electronics module was difficult and expensive to manufacture. For this reason, a study was initiated to design a new module that would be simple, inexpensive, and equal in quality to the existing version.
At the start of this study, it became obvious that several factors enter into the manufacturing cost of the electronics module. Each of these aspects must be considered to achieve a package with a high overall manufacturing efficiency commensurate with the end use:
1. Chassis costs - How much does it cost to fabricate the chassis parts, apply finish, and assemble a finished chassis?
2. Electronic components - Both cost of discreet components and the time necessary to install them must be considered.
3. Wiring cost - The total number of wires, the number of shields requiring termination, the use of crimp terminals versus solder lugs, and the accessibility of the various connectors all enter into this cost.
4. Quality control - The total time necessary to inspect each assembly for errors becomes important. Printed circuits are easiest to check; harness wiring, the most difficult.
The rigor with which these guidelines are followed will determine the success of the final design. The following description covers the more interesting aspects of the new module design and illustrates the type of decision that must be made. First, the packaging problem will be described, and then a brief circuit description will be given.
The most important step in the initial design of the module was a decision to make all of the controls such as switches, gain controls, and indicator lamps part of the printed circuit card assembly. Also, the number of cards would be reduced from eight to one or two. Since each card assembly must contain over one hundred components, the surface area must be quite large. Boards with printed traces on both sides were ruled out because of cost and lack of dependability with plated through holes. A minimum of 20 pins on each board would be required to provide the necessary interconnections. The use of a single row 20-pin connector prohibits vertical boards since the connector length is an inch greater than the total module height.
Once the use of horizontal cards was established, the next problem was the placement of the cards within the module. The best locations for the card would be against the bottom of the module with the components above, or at the top of the module with the components hanging downward. Since all of the connectors for line and head cables are near the top of the chassis on the rear panel, a card at the top was chosen to shorten the lead lengths from the card connector to the external plugs. This placement also facilitates assembly procedures and eliminates the need for wiring jigs.
The use of two cards was selected as the best compromise between simplicity and serviceability. The left card assembly contains the record amplifier, playback preamplifier, record relay, and overdub circuitry. The right card assembly contains the line amplifier, bias and erase buffer amplifier, A-B switching circuits, and meter monitoring switch.
The remaining components - the output transformer and the VU meter - are mounted in the center of the module. The bracket to which they are attached also serves as a structural member, a card guide for each card, and an anchor point for the card assembly latch.
Each printed circuit card is attached to its mating front panel at three places. This assembly forms a "T"-shaped structure that adds extra rigidity to both the front panel and the printed circuit card. The front panel is slotted to allow access to the calibration controls. During normal operation the slots are covered by a trim strip, but the strip can be removed by simply releasing the two panel snap-latches. These latches also serve as handles to aid removal of the panel and card assembly from the module.
The lightweight sheet metal parts for the module form a monocoque structure that is extremely rigid. The "V"-shaped rear panel acts as the main beam of the assembly, and the four upright members and the top and bottom sheets form a monocoque box. If the module is supported by blocks at each end, the center of the module will bear a load of more than 150 pounds without any extreme deformation.
The various fasteners were chosen with effectiveness, cost-, and installation ease as the criteria. These fasteners include eyelets for securing card guides, connectors, and switches; and self-locking nuts where screws are required.
The following sections describe the electronic circuitry that has been developed for the new module. Where possible, a comparison is made with the present circuits.
Three changes were made to the current record circuit:
1. The input transformer impedance and turns ratio were changed to give a higher voltage level to the first transistor,
2. The gain pot was placed before the input transformer, and
3. The monitor circuit is fed from the first transistor emitter rather than in parallel with its base.
The input line feeds through a high impedance record gain control to the primary of the input transformer. Since the minimum input level is -20 dBm with the record gain control set at maximum, the transformer never sees more than a -20 dBm reference level at 0 VU. For higher line levels, the gain control attenuates the signal to the desired -20 dBm level.
The transformer secondary feeds an amplifier stage that brings the signal up to a high level before insertion into the R-C pre-emphasis network. A junction field effect transistor that acts primarily as a low-noise impedance transformer follows this high impedance circuit.
The FET output is coupled to a Darlington output pair. The output stage collector feeds the head through a series resistor to achieve constant current recording. The emitter of the output is bypassed with a pair of transistors connected as diodes that act as a third-harmonic distortion compensating circuit.
The feed to the line amplifier for source monitoring is extracted from the first stage emitter. An extra amplifier stage allows monitoring at any output line level up to +14 dBm.
The new playback preamplifier is quite similar to the present circuit. The head feeds a two-stage equalizer amplifier that has adjustable high frequency and low frequency gain. This is followed by a phase rotation network to compensate for phase shift due to the record head characteristics. A low impedance output is derived by using an emitter follower. Equalization and phase correction are selected by a reed relay controlled by the transport speed switch.
Some minor changes were made to decrease cost and improve performance. The use of an active filter on the power supply bus allows the operating voltage to be raised from 18 volts to 26 volts. This raises the clipping level of the phase corrector to allow the use of future heads that have a higher output level.
The introduction of less expensive epoxy-packaged transistors permitted savings of more than one order of magnitude on the input transistor. Similar savings were also made in the other circuits, but many of the transistors were already low-cost epoxy packages in the previous design.
The line amplifier is a complementary symmetry amplifier using a matched pair of germanium transistors in the output. For this application, the limited bandwidth of the germanium transistors is unimportant and their relatively high gain allows a direct drive without the usual matching transistor for each output element.
The existing machines use a matching network to make the line amplifier output look like a 600 ohms source. The new modules use a low impedance output that conserves the 5 dB lost with this network. This means the output transistors do not dissipate as much power at the +28 dBm maximum level.
A large amount of overall feedback is used to achieve flat response and low distortion. The maximum distortion at +28 dBm and 20 Hertz is less than 1%. Response is down 3 dB at 55 kilohertz due to transformer loss and controlled rolloff in the amplifier.
BIAS AND ERASE AMPLIFIER
All 3M master recorders have used a master oscillator in the transport and buffer amplifiers in each electronics module. The current machines have two separate amplifiers for bias and erase because the erase buffer is used for the Dynatrack bias supply when the machine is used for Dynatrack record. In the new module, Dynatrack does not require the extra supply, so there is only one buffer per track.
The buffer amplifier consists of a bridging input transformer, a push-pull driver amplifier, and a push-pull output amplifier. A conventional coupling circuit is used to drive the heads.
The noise balance circuit in the bias supply has proven itself in the previous 3M machines. Its most important feature is that it uses the bias voltage to derive its own correction voltage. The correction only appears when the bias is energized so that there is no need to worry about introducing a permanent magnetization into the head.
The input impedance was kept as high as possible to provide for the possibility of a 16 track recorder in the future.
A -B SWITCH
A-B or source-tape monitor switching is accomplished by a relay on all 3M machines. This allows simultaneous switching of all tracks from a master button on the transport. Each module also has buttons so that each track can he switched on an individual basis.
A common power supply is used to feed all tracks of electronics. The supply contains two regulators - one for signal electronics, and the other for control circuits and light bulbs. This load division greatly simplifies the problem of eliminating clicks that might feed from relays or lights into the record or playback amplifiers. Each regulator has short circuit protection.
Since the new modules are smaller than the current ones, it is now possible to use consoles with eight modules below the transport or eight modules in a mounting bay above the transport. One, two, three, and four track versions are also readily available.
When the modules are mounted above the transport, the console framework provides complete protection for all the connectors and cables. This allows the machine to sit flush against a wall and also permits the machine to be shipped laying on its back for added safety.
DISCRETE COMPONENTS VERSUS INTEGRATED CIRCUITS
Integrated circuits were investigated during the circuit design phase of development, but no competitively priced circuits were found that had the necessary power level, reserve capability, low noise performance, and low distortion. Most of the circuits were designed for applications where distortion is always present and 10% is maximum. In the future, better circuits will become available, but applications with 110 dB dynamic range, several watts output, and low distortion are still the province of discrete devices.
The design of a low-cost electronics package for professional audio recorders does not necessitate any sacrifice in quality if the overall manufacturing efficiency of the package is optimized. The module described here demonstrated how this can be done by straightforward design if one allows a little imagination to aid the designer.
The module that is described here retains all of the features of the present version, but uses only 40% of the former board area, 30% of the former number of wires, and requires fewer hours to assemble. These improvements were achieved without any sacrifice in performance or dependability.
The author wishes to acknowledge the work of Don Kahn who deserves credit for many of the mechanical innovations incorporated into this new module.

There are several types of structured cabling in Dubai. Listed below are some of the main components. These include transmission media, main and intermediate cross-connects, terminations, and horizontal cabling. To learn more about these types of structured cabling, read on! Until next time, happy networking! And remember, there is a good reason why structured cabling is so important. It is not just for the technology it provides but also for the safety of people around it.
Installing horizontal cabling can be easy if the wiring runs along the ceiling or walls. However, the cables must be installed carefully because EMIs from photocopying machines and elevators can damage them. If you need to install horizontal cabling, you can use multimode fiber-optic cabling, which can run longer distances. Similarly, for voice and data transmission, you can use UTP cabling. Patch cables should be no longer than 6 meters to avoid interferences from other components.
There are several different types of transmission media for structured cabling. Choosing the best one for your network depends on several factors, including the intended use of the system, ease of installation, and maintenance.
Main and intermediate cross-connects:
The building and floor distributors are the two main cross-connects in a structured cabling system. In a multitenant building, both main and intermediate cross-connects may be located at the same location. In other buildings, these connectors may be separated by a distance, so they are more economical to bypass.
Before starting to terminate cables in your structured cabling system, you should plan where they should be terminated. Ensure that the cable length is sufficient and untwisting the wires just enough to press them down. Next, you should label the wall outlets and ensure the cables are placed in a tidy bundle. You should label the end of each cable with its manufacturer and product type. You may need to bundle multiple cables to reach a specific area.
Structured cabling has many subsystems: entrance facility, main equipment room, telecommunications rooms, individual workstations, and backbone cabling. Entrance facilities connect outside cabling to the building’s backbone cabling system. These components include network demarcation points, connecting hardware, protection devices, and other equipment connected to network providers. The network demarcation point, also known as NFID, is used to identify which cables belong to the network of an outside service provider.


The WaterRower Digital Heart Rate Receiver, uses state of the art ANT+ wireless technology to communicate with the Digital Chest Belt ANT+ Transmitter (required item not included, see Accessories).
Digital heart rate monitors have a transmission distance of 1.5 meters (as opposed to 1.0 meters for analog monitors, such as Polar). This allows the receiver to be placed internal, or adjacent to the monitor removing the need for unsightly extension cables. Further, the use of digital technology improves accuracy and reliability.
ANT+ digital wireless technology greatly improves the range and accuracy of heart rate information and is becoming widely adopted by industry leaders such as Garmin, Suunto, Timex, etc.
ANT+ Heart Rate Monitoring is compatible with Series 4 or newer monitors only, however, it will NOT fit on the M1 models.

China’s Yangtze Optics Africa Cable (YOAC) which, together with joint venture partner, Mustek, is building a state-of-the-art optical fibre cable manufacturing plant at Dube TradePort, has sent eight of the 120 South Africans it will employ there to China for training.
Construction of one of the biggest plants of its kind in Africa is being fast tracked with the support of KZN provincial government.
The JV partners are investing R250 million in the new facility and will create 150 jobs.
The 15 000m2 manufacturing facility is scheduled for completion in November this year. Production will commence in December and the plant is expected to be fully operational by January 2017.
It will have manufacturing capacity of more than one million fibre kilometres and will supply cable to fibre-to-the-home service providers, the private sector, mobile telecommunications providers and the public sector.
The Chinese training programme covers the full spectrum of fibre cable manufacturing from optic fibre colouring, secondary coating, stranding, sheathing to cable testing and quality control.
High tech skills like this are in short supply in South Africa.
On completion of training in mid-September, the team in training will head back to South Africa to train the rest of the teams that will run the South African plant.
YOAC has committed itself to a four-year skills development plan to expand local skills in specialist roles in optical fibre cable manufacturing.
Speaking about the training experience, Velile Mngonyama, production supervisor at YOAC, said that although he did have training and some experience in cable production, the precision and detail required to produce optical fibre was at a different level.
“Although the processes for copper cable manufacturing and optical fibre are similar, the technical specifications and applications for optical fibre are totally different. The experience has been an eye opener and we cannot wait to come back home to share what we have learnt with the rest of the team in South Africa,” he said.
Another participant in the training programme, Mohammed Rawat, the maintenance manager, at YOAC, added: “The optical fibre industry is totally different from the copper cables that we are used to. Although the industries are similar, the plant management, maintenance and technology used is much more advanced. The training has been intense.”
Pieter Viljoen, CEO of YOAC, noted that, while copper cables had been a reliable medium in the past, optical fibre was the future and would definitely change the way in which people and businesses connected.
He added that, over the next few years, fibre optic network rollout would increase significantly as developing countries invested in fibre networks that were faster and much more reliable.
“With increased demand for fibre optic networks, there will be a need to train local people to set up fibre optical local manufacturing plants to supply the anticipated huge potential market,” he said.
Referring to the recent China (Guangdong) – South Africa Economic and Trade Cooperation Conference, Viljoen reiterated that, when Chinese companies invested in South Africa, they tapped into local resources. Where there were skills gaps, they had to upskill and train local people.


The definition of net neutrality is (from wikipedia):
Net neutrality is the principle that Internet service providers and governments regulating the Internet should treat all data on the Internet the same, not discriminating or charging differentially by user, content, website, platform, application, type of attached equipment, or mode of communication
The issue is that Videotron in Quebec was not counting a certain streaming service’s data usage against customer’s data cap. This meant if you streamed 300mb of data from the service, it would not count against your 4gb data plan, but if you used a competing service it would count.
That is a direct attack on net neutrality, where an ISP or mobile network provider is directly favouring one service over another, which distorts the free market. We will see today what the CRTC has to say about it.

INYO COUNTY VOWS SUPPORT
continued from previous page
After 10 years of running full speed headfirst into brick walls, finally Darwin garners some outside help!
On Feb 19, 2010, unofficial representatives of the unofficial Bring Broadband to Darwin (BBD) ad hoc committee met with Brandon Shults, IT Director for Inyo County, who pledged support for getting broadband for Darwin.
The aid offer coincides with a large project to redo fiber-optic lines up Owens Valley (Digital 395) . When finished, fiber-optic lines would be 38–40 miles from Darwin, but the county thinks that they can help by teaming Darwin's need with the Owens Valley project.
But there always seems to be a catch 22: If Verizon does offer Darwin DSL, then Digital Last Mile grant funds cannot be used to help Darwin obtain broadband because of grant stipulations.
Money wouldn't be available from the Digital 395/Last Mile grant(s) for at least two years, if the money comes through at all. The California Broadband Coop (Praxis) is administering the grant, which is mostly federal stimulus money with a small portion of matching funds provided by the California Public Utilities Commission.
No plans to lease T1
BBD representatives stressed that there are no plans to have a public or private entity lease a T1 line and distribute it in Darwin. Administration, billing, hardware acquisition, funding and other organizational and implementation facets would be a nightmare, judging by past town-wide efforts. This leaves Verizon as the main choice to activate the T1 option and provide DSL for Darwin. Inyo County previously thought that Darwin was shooting for a non-Verizon solution. One county source at the meeting shared that the county also has had problems historically in many dealings with Verizon, especially with upgrades.
Other possible ways to disseminate broadband were discussed, including approaching another Internet Service Provider (ISP). Although the main private local Owens Valley ISP opposed the Digital 395 project, that ISP could possibly disseminate DSL in Darwin from a leased T1 line, either with hard wire, fiber optics or a wireless solution. This local ISP originally proposed a wireless Owens Valley solution instead of the fiber-optic corridor now being constructed.
Inyo County pledged that they would:
1. Verify that T1 service is available through Verizon.
2. Notify California Broadband Coop of the “Broadband for Darwin” website.
3. Contact Verizon directly to see if they will offer DSL to Darwin.
4. Approach other area ISPs (if Verizon absolutely will not install DSL) to see if they would be interested in leasing a T1 line; installing a remote mini DSLAM switch; and supplying DSL to Darwin.
Stay tuned and see if the universe indeed smiles on Darwin, and the town finally gets broadband. Although BBD committee is hopeful, recent talks with Verizon ended in more double-talk and the usual mantra about installing broadband in Darwin: We can't; we won't; we don't know how.


In a world that moves fast and relies on being connected at all times, you can’t afford to have unreliable internet. The Niagara Regional Broadband Network (NRBN) understands this and is committed to providing the community with ultra-reliable fibre optic network. Serving people across the Niagara Region, NRBN delivers a network that is limitless, and faster than other forms of internet such as DSL, cable, and wireless internet. Their goal is to become a technology and innovation leader in the Region and help communities to connect faster with a more reliable network. However, their branding and website design was not supporting the goals and direction of the company.
Enter Symetric Productions. Our team worked with NRBN to refresh their brand and website to align with their goal of being a leader in technology and innovation. A clean and professional approach to the design allowed the website to remain informative, yet simple for users to navigate. Similarly, when designing the logo, we focused on simplicity and clarity to create a consistent visual experience that identifies NRBN as a leading internet service provider in the Region.


I’m about 3/4 of the way through my internship with Boeing, and I wanted to share with all of you what I’m doing, why I chose it for an internship, and why its so AWESOME!
Last summer and this summer, I’ve worked in Boeing’s Satellite Development Center in El Segundo, and I’ve been extremely lucky to find that my background in Astronautical Engineering has prepared me pretty well to work on satellites and that I love doing it. I believe I’ve mentioned before that what makes spacecraft engineering so interesting is the added challenge of designing something that has to be virtually perfect. Not only does your design have to withstand extreme conditions, you cannot go fix it if anything might go wrong, and TRUST ME they do.
In 2011, I worked as a bus test engineer, verifying the health of all the units that make up the “bus”, which is responsible for: propulsion, attitude control, power (solar wings and batteries), getting telemetry data from the spacecraft and sending commands, and maintaining normal temperatures. These components are all crucial to spacecraft flight, but the thing I was really interested to know more about was the Payload!
The payload is the moneymaker, because it is responsible for performing whatever operation the customer wants, which, for Boeing, is usually to send communications signals. We make alot of satellites that are referred to as “comsat”. This summer I am a Payload Systems Engineer on a program that covers the entire globe, and as such, it is my job to make sure that the signal sent up (maybe a phone call by a US soldier in the field) makes it where it’s supposed to go. This is a very simple concept, but can be very difficult in execution.
The simplest type of comsat payload is what is referred to as a “bent-pipe” payload, because the signal is not checked or encrypted or changed at all, just sent back to another location. The top-level design for a bent-pipe satellite will always be very similar: antenna, low noise amplifier (because the signal is initially very small), input filters to get rid of any noise from Earth, high power amplifiers to be able to send the signal back to earth, output filter to eliminate noise from satellite hardware and signals adding together, another antenna.
Where it gets complicated is the extreme level of precision necessary to ensure that the signal stays as clear as possible. Also, converting the analog microwave signal into digital data adds another layer of complexity.Things can get complex very quickly and even the littlest error, like a bit of debris in a tiny sensor, can throw off the manufacturing process and take days and $$$ to find and fix.
I knew absolutely NOTHING about communications engineering when I came here, and I’ve been working with a team of electrical engineers who are baffled that I don’t know about coupling and beamforming and whatever else they think up! However, I’m learning alot, my work is interesting, and every day is a new challenge. I’m continually reassured that I want to go into the satellite industry!


OneWire delivers computing resources without ever requiring you to buy server hardware. The system is built upon industry-leading virtualization and cloud computing technologies.
Cloud Computing technology is where server hardware is shared by many users, similar to how a roadway is shared by motorists. With this infrastructure approach, hardware is purchased, managed and maintained seamlessly by a third party.
Virtualization technology separates a server from the physical hardware that it operates on. When deployed optimally, this reduces failures, increases reliability, and delivers savings.
Everything is redundant. Each pod consists of several clustered hosts, multiple switches, a redundant centralized storage array and battery backup. Connections between components within the pod are also redundant, so no matter what may fail, the system keeps seamlessly running.
Each pod is connected to the internet through multiple connections using independent infrastructures. This prevents service interruptions in case of a connectivity outage. Multiple power sources are backed up by generators with battery backup to combat any blackout scenarios.
