Abstract: Understanding the physics of nanoscale devices and related material properties are essential requirements to sustain the existing technologies and also to develop next-generation technologies. In recent times, low power devices have become the need of the hour. However, fundamental physical limits are among the major roadblocks towards realizing energy-efficient devices. In this talk, I will discuss one of the fundamental physical limits in silicon transistors, termed Boltzmann Tyranny, which needs to be overcome to achieve low power devices. I will discuss the details of the problem and various approaches to solve it through an understanding of the device physics and also by integrating new materials using advanced nanofabrication techniques. Further, I will discuss the development of ferroelectric non-volatile memory using 2D semiconductors. I will also briefly discuss some of the research work done on optoelectronic devices including UV and broadband photodetectors as well as random lasers. Finally, I will discuss key requisites of nanofabrication and of device physics which are crucial for the successful development of quantum devices and related technologies.

PLC4TRUCKS is a SAE J1587 based networking standard that uses Spread Spectrum Power Line Communications (PLC) over the DC power bus to transfer information back and forth between a tractor and trailer. Other communication standards such as SAE J1708 and SAE J1939 are well established in the industry and are well suited for control and monitoring applications. However, both of these standards are "wired" solutions that utilize unshielded or shielded twisted pair. PLC4TRUCKS does not require any installation of new wires between the tractor and trailer.
The problem is that the standard SAE J560 connector does not have any extra wires (or pins) for J1587, J1708, or J1939 communications. Many solutions have been proposed to solve this problem including the addition of a second connector, pin multiplexing of the existing J560 connector, wireless solutions such as infrared (IR) and radio frequency (RF), and power line communications (PLC) solutions that use the DC power bus. Each has met with limited success in the marketplace for reasons best explained by the medium.
· Low Cost - Since one of the primary reasons for bring new communication solutions to market is to reduce operating costs and improve efficiency, it is imperative that the maintenance costs as well as the initial costs of the new solutions are low. PLC communications achieves this by not requiring the installation of a second connector and uses the vehicle's existing wiring to transmit information. Furthermore low cost is achieve by keeping the electronics "simple" by not requiring any multiplexing or RF circuitry.
· Reliable - Any communications device on a vehicle must be reliable and sound both from a technical design and maintenance perspective. On a software level, PLC achieves this by using the industry standard SAE J1587 protocol. On the hardware level all products designed and manufactured by Hegemon are design to operate and withstand the harsh conditions within the automotive environment.
· Flexibility - PLC communications is a hardware and software solution thus making it extremely adaptable to many different applications. In addition, the hardware requirements are small thus making the modules relatively small in physical size. This makes them easy to place just about anywhere within a vehicle.
· No Additional Wires Vehicle Network
- ABS Warning Information
- Tire pressure information
- Trailer temperature
- Trailer door status
- Engine data to wireless transceiver located on trailer
- Information to driver received through a wireless transceiver
- Cargo status
· In Cab Display Units
· In Cab Warning Devices
· Vehicle security
· Smart Trailer Door Sensors
· Gateway Products
- PLC to RS232
- PLC to J1939
- PLC to J1708
PLC4TRUCKS offers proved power line Spread Spectrum Carrier technology to solve the problem of tractor-trailer communications. Hegemon Electronics is in a position to provide system and design expertise to produce low cost products and/or solutions that solve the problem of tractor-trailer communications.
The result will be an SAE J1587 network that operates seamlessly over the DC power bus instead of its typical J1708 twisted pair network. The industry will benefit from a low-cost, highly reliable, and SAE J1587 compatible solution that enables new applications to emerge for increasing safety, improving efficiency, and reducing overall cost.

5G ushers in a new world of opportunities
What’s ahead for telecom providers in 2019? Fifth generation (5G) wireless technologies will be gaining ground quickly, unleashing the full potential of augmented and virtual reality, Smart Cities, and IoT. Mic Locker, managing director in Deloitte Consulting LLP’s Technology, Media & Telecommunications (TMT) industry practice, shares her thoughts on opportunities for growth in our new telecom industry overview.
2019 will present several opportunities for providers to bolster current revenue sources-or to create entirely new revenue streams. Many of those opportunities will arise from changing market conditions and consumer preferences-and from the first large-scale rollouts of 5G technologies, which are expected to create significant business opportunities for telecom companies.
Even before the rollout of the 5G, there is work to be done. Consumers continue to display an insatiable appetite for mobile data. With more data-heavy applications securing their place in consumers’ daily lives, we only expect this trend to continue. Consumers demand higher data limits, and they opt in for unlimited data plans. According to the US edition of Deloitte’s 2018 Global Mobile Consumer Survey, 37 percent of respondents now have unlimited data plans—up from 25 percent in 2017.1 We now see providers offering lower prices for these plans as well as a variety of bundled services, decreasing the average revenue per user (ARPU). To balance the competitive landscape and possibly stabilize pricing, telecom companies will likely be looking to expand their boundaries and search for new opportunities.
One of the main opportunities could come from consolidations and partnerships, especially in the areas of cable and content. Today, we observe a high number of consumers who prefer video streaming services over cable subscriptions. Our Digital Media Trends survey revealed that 55 percent of US households now subscribe to paid video streaming services while pay-TV penetration fell to 63 percent-down from 75 percent the previous year.2
In response, cable companies are looking to augment their pay-TV business with communications services—and by extending their programming distributions beyond fixed lines. Changing dynamics and competitive pressures from both sides can encourage telecommunications providers to consider M&A deals to integrate content and media into their offerings. Partnerships are also likely to increase as providers attempt to accelerate development of new business models and services based on 5G technology.
Once available, 5G is expected to create significant business opportunities for telecom companies,3 helping them gain revenue in the fixed broadband market and business-to-business (B2B) opportunities such as smart cities and Internet of Things (IoT). It will also provide the ideal environment for telecommunications providers to employ “network slicing” to customize their offerings.4 In the context of 5G, this will enable sharing of a given physical network to run IoT, mobile broadband, and very low-latency applications-including many connected-car and connected-home functions that have the potential to create entirely new revenue sources for providers in 2019.5
Two other key revenue-generating opportunities for telecom providers will be mHealth and mPayments. In the area of mHealth, operators can monetize services targeted to the growing number of subscribers who have adopted health care–centric wearables to, for example, help them ensure they’re taking the proper dosages of medications. In the world of mPayments, on the other hand, mobile operators can play a different role: As an integrator for devices, applications, methods of mobile payment, and customer identity management. One study estimated that this strategy could help telecommunications providers increase their mobile payments revenue at least fourfold by 2022.

The Tile by Bendac is a revolutionary LED display that is both ultra-slim and modular in nature, making it the latest in flat-panel LED display technology. It utilises a standardised module size of 400mm x 300mm allowing for displays to be created in both 16:9 and 4:3 aspect ratios.
The Power Display Units (PDU) can be located up to 10 metres away from the display to allow for the screen to sit as close to the wall as possible. This system also ensures and heat is drawn away from the display, unlike most conventional LED displays where the PDU is mounted on the back of the panel, this system helps to extend the lifetime of the display.
The Tile uses customised ribbon cables which transmit both power and data to the modules via premium-quality cables and connectors, this allows for a safe and reliable connection between each module. The slim and lightweight magnetic modules can stick to the customised frame and any construction design and needs very little space for the wires and mounting.

I have three Netgear Routers: WNDR3700, WNDR4000, and WNDR4500.
On the SAME wired network, the 3700 works great. But both the 4000 and 4500 exhibit the same symptom. They periodically drop WAN connections for a minute (almost exactly), then allow them for 5-20 seconds, drop them for another minute, etc. In the plots below, red in the time graphs means that traceroutes and pings are not getting returned by the affected hops along the path (top part of the plots).
Existing connections (Netflix streaming) seem to not be affected. I see this periodic dropping clearly doing traceroutes or pings. Pingplotter is especially effective at showing this.
This is what a normal Pingplotter connection (on the WNDR3700) looks like:
It is normal for the destination (the Comcast nameserver) to refuse to answer some packets. The white area on each plot is the jitter, which increases up to a loss, and then drops.
What could be causing this?
Snoopytime on the Netgear Forum suggested:
Try going to Setup, then to WAN Setup . . then UNCHECK 'IGMP Proxy Disable'.
I think I figured it out. Pingplotter sends multiple ICMP requests. The router apparently has trouble dealing with these when queued up.
I modified Pingplotter to send them serially, and the problem went away.
So what is causing it? Well, someone on the forum said that what happens is that the router loses its DNS addresses. This would be consistent with my symptoms during the periodic outages: existing connections continue to work, new ones do not. The person suggested that I put in the fixed Comcast DNS addresses (220.127.116.11 and 18.104.22.168). But I also installed the latest Netgear beta firmware which he said supposedly fixed things. And it has been working using the unmodified Pingplotter for 14 hours now.

The advantages of RFID and how to use RFID technology[BOHANG]
What is the RFID technology?RFID (Radio Frequency Identification), commonly known as "electronic tag", is a non-contact automatic identification technology that automatically recognizes target objects and acquires relevant data through radio frequency signals. The identification work does not require manual intervention as a wireless version of the barcode. RFID technology has the advantages of waterproof, anti-magnetic, high temperature resistance, long service life, large reading distance, data encryption on the label, larger storage data capacity, and free storage information. The application will be for retail, Logistics and other industries have brought about revolutionary changes.
The RF tag is physically composed of three parts: a tag, an antenna, and a reader. Tag consists of a coupling element and a chip. Each tag has a unique electronic code. The high-capacity electronic tag has a user write area attached to the object to identify the target object. Reader: Read (sometimes A device that can also write) tag information, which can be designed as a handheld or fixed type; Antenna: transmits RF signals between the tag and the reader.So what is the characteristics of RFID technology.
1,Data storage: Compared with the traditional form of the tag, the capacity is larger (1 bit - 1024 bit), the data can be updated at any time, can be read and written;
2,read and write speed: compared with the bar code, no linear alignment scanning, faster reading and writing, Multi-target recognition, motion recognition;
3,Easy to use: small size, easy to package, can be embedded in the product; 4,Safety: special chip, serial number unique, difficult to copy;
5,Durable: no mechanical failure, long life, resistant to harsh environments.
After learning these knowledge of the RFID technology,now do you what application field is it use.As a data carrier, electronic tags can play the role of identification, item tracking and information collection. In foreign countries, electronic tags have been applied in a wide range of fields. The RFID system consisting of electronic tags, readers, antennas and application software is directly connected to the corresponding management information system. Every item can be accurately tracked. This comprehensive information management system can bring many benefits to customers, including real-time data collection, secure data access channels, and all product information offline. Wait. In foreign countries, RFID technology has been widely used in many fields such as industrial automation, commercial automation and so on.


The Electronic Data Exchange or EDI is a technology that helps trading organizations and partners get more done faster by speeding up logistics timelines and eliminating manual errors through business to business communication automation. EDI allows organizations that produce, ship, purchase, and sell goods or provide services such as retailers, manufacturers, insurers, health care providers, airlines and more.
EDI has been in use since the 1960s, though it is finding new use today by enabling supply chain automation and acting as a key part of the workflow for business process automation. By the end of this blog post, you should have a fairly solid understanding of EDI and an introduction to the basics of EDI technology.
Computer-to-Computer Data Exchange
EDI is an automated computer-to-computer exchange of standard electronic business documents that occurs between business partners over a standardized and secure connection.
With computer to computer communications, there is no need to rely on manual options such as email, facts, and postal mail. Documents move directly from the sender’s computer application to the receiver’s computer application. For example, a buyer can send over a purchase order and the supplier will automatically send over an invoice.
Thousands of standard business transaction documents can be spent automatically with EDI. Common examples include purchase orders (EDI 850), shipping statuses (EDI 214), invoices customs information, payment confirmations (EDI 820), and inventory documents.
The standard EDI format allows computers to process EDI documents. Standards describe each piece of data and the format, such as the type of document, the parties involved, the date common and the actions to take. The use of standards eliminates company to company variations so that each business partners computer system speaks a common language.
EDI systems use a variety of standards for various regions, use cages, and industries. The EDI standards have different versions, so EDI partners have to use the same standard and version for the data to flow properly.
Among the most popular standards are ANSI X12 used in the United States, UN/EDIFACT which is used globally, and industry specific standards, such as HIPAA.
EDI uses a range of secure protocols for document exchange. Partners have to agree upon the protocol to use and make sure they are using the same protocol before they can exchange EDI files. If they do not, they must work with an intermediary to facilitate the exchange between the two protocols.
Certain EDI security protocols require more technology than others but using EDI software such as ESSBUS Connect can facilitate a wide variety of exchanges without a major investment.
These protocols range from the long-established file transfer protocol (FTP) or secure FTP (STFP) that is used to upload content to a host server for a website, to API-based systems such as AS4, web-based via A2, and other options, including mobile EDI.

Prolonged exposure to loud noise can lead to permanent hearing damage. Always keep the volume as soft as possible and keep the sound pressure level as low as possible when using the loudspeaker for a long time. Headsets can output sound with a high volume and high tones. Exposure to such sounds can lead to a permanent hearing loss. The volume may vary depending on the circumstances, such as the phone you are using, the reception, volume settings and their environment. Which safety guidelines could you follow before using a headset? And the recurring question, does blue-tooth radiation damage your brain cells?
Safety guidelines for your hearing
Go through the following steps before using a headset:
- Before listening to the headset, turn the volume knob to the lowest level.
- Then turn on the headset.
- Then adjust the volume control slowly to a comfortable level.
- Keep the volume as low as possible and avoid using the headset in noisy environments where you are more likely to turn up the volume.
- If a higher volume is required, adjust the volume knob slowly.
- If you experience an unpleasant feeling or a ringing sound in your ears, stop using your headset immediately. Visit a doctor.
With prolonged use at a high volume, your ears can become accustomed to the sound level. This can lead to permanent hearing damage without feeling anything from it.
Using the headset while driving a motor vehicle, motorcycle, boat or bicycle can be dangerous and is prohibited in some countries. Observe the applicable local legislation. Be careful when using your headset for activities that require your full attention. In such activities, keep the headset away from your ears or switch off your headset so that you do not get distracted and avoid accidents or injury.
Of course, you want to know if Bluetooth is safe. For the safety of using you have to look at two things. The transmission power and the security of the connection. Let’s start with the first.
Transmission power (radiation)
Here the question arises: Is the use of Bluetooth devices safe for your health? I have read that channels can pose a health hazard?
The transmission power of, for example, a Bluetooth headset, which is close to your head, is so low that no measurable consequences for your health have been measured.
Research is carried out regularly by various organizations around the world on the health effects of radio stations on public health. This concerns the influence of both heavier transmitters used in telecommunications and transmitters in consumer electronics, including mobile phones, WiFi and Bluetooth. Research has shown that high transmit powers that cause high electromagnetic field strength can heat the human body. In order to prevent unnecessary warming, norms have been drawn up for both citizens and employees who deal with transmitting installations professionally. To go further into this phenomenon, we need some simple physics.
In case of a radiating antenna that emits its transmitting power approximately spherically, the amount of electromagnetic radiation decreases, with the square of the distance to the antenna. This means that the further you are removed from a transmitter, the less you are exposed to electromagnetic radiation.
The transmission power of a device is a measure of the amount of electromagnetic radiation emitted via the antenna. The transmission power is indicated in Watt (W) or milliWatt (mW) 1,000 milliWatt = 1 Watt. The transmission power of the different devices can vary widely. Also, the distance to your head, one of the most vulnerable parts of the human body, is often not the same.
A comparison of transmission power.
- A smartphone gives a maximum power of about 1 Watt
- A WiFi router or WiFi transmitter in a Laptop gives a transmission power of up to 100 mW
- A Bluetooth Class 2 headset has a maximum transmit power of 2.5 mW.
- A Bluetooth class 3 headset gives a maximum transmit power of 1 mW.
Do blue-tooth radiation damage your brain cells? – A lot less than keeping your smartphone close to your head.
We can assume that the distance to the head with a Bluetooth headset and a mobile phone is about the same. The transmission power of a Bluetooth headset is a lot lower up to 2.5 mW = 0.0025 Watt at class 2 and 1 mW at class 3, compared to the 1 Watt of a mobile phone.
For Bluetooth class 2: 1 W / 0.0025 W = 400 times less radiation load
For bluetooth class 3: 1 W / 0.001 W = 1000 times less radiation load.
Bluetooth Security of the connection
Another aspect of safety is the security of the connection and tracking by third parties. By security, I mean that connection cannot be listened to. By tracking, I mean that you can be followed by third parties such as advertisers in, for example, shops with a switched-on Bluetooth device.
Encryption is a technique to make data unreadable and unusable for someone else. The latest models, Bluetooth version 2.1 and higher, do have a default encryption key. In the past, a number of security holes have been found in the Bluetooth system that has been fixed. With version 4.2 a great deal of attention has been paid to stronger and better security. For normal use, Bluetooth is safe to use on a daily basis. If you still have doubts, turn off your Bluetooth connection on both your smartphone or computer and your Bluetooth speaker or headset after use.
A much less familiar topic is the tracking of Bluetooth devices. A device that is switched on regularly sends a signal to check whether another device with which it is paired is nearby. The device identifies itself with a so-called MAC address. A MAC address is not only used for Bluetooth but is also used with WiFi and wired internet connections. In principle, a device can be identified on the basis of the MAC address. This is relatively easy with Bluetooth. Your smartphone Bluetooth MAC address can be used to map your movements and repeated visits in shops and public buildings. In order to prevent this, a function has been built into the Bluetooth 4.0 specifications that allow the device to change MAC address regularly. In this way, your privacy is much better protected. If you have WiFi on your smartphone, you can be tracked via the WiFi Mac address of your smartphone or laptop. This is more accurate than via the phone signal, but less accurately than via Bluetooth. Do not forget that you can also be tracked via the signal from a smartphone. Telephone companies can see where you are located, although that is a lot less accurate than via Bluetooth or WiFi.
Tracking possibilities of smartphone signals
- Smartphone signal: At street level by the telephone company
- WiFi: By anyone with the right equipment and with an accuracy of several tens of meters, so say on building level.
- Bluetooth: Equipment lower than version 4, for everyone with the right equipment, with an accuracy of a few meters, so approximately on shelf level in a store.
Bluetooth equipment with version 4 or higher, tracking only possible for a short time, without your permission. This can be done via an app of a store chain in which this function is activated.
If you want to be sure that you are not being tracked, switch your phone to airplane mode, or just leave it at home.

How to make your Nokia N95 a hotspot?
February 9, 2008
Robert Scoble made a post about Joiku turns Nokia N95 into Wifi hotspot and that caught my eyes because of my love to nokia and leaning new features this phone has. So what is a hotspot? a hot spot (or hotspot) is a wireless LAN (local area network) node that provides Internet connection and virtual private network (VPN) access from a given location. For example, a business traveller with a laptop equipped for Wi-Fi can look up a local hot spot, contact it, and get connected through its network to reach the Internet and their own company remotely with a secure connection. Increasingly, public places, such as airports, hotels, and coffee shops are providing free wireless access for customers.
JoikuSpot a free mobile software solution that turns a Nokia Smaprtphones to a WLAN HotSpot.
JoikuSpot enables S60 Smartphone to share it’s 3G internet connection wirelessly over WLAN with any compatible WLAN device such as laptop or other Smartphone like Apple iPhone. More than one device can connect to JoikuSpot in parallel and seamlessly share the same 3G internet connection. JoikuSpot acts an internet gateway to external WLAN devices.
Now, I love to lay my hands on of Nokia’s new N-series cellphones which you can read more about here.
Hope you guys find this interesting because I did 🙂

Network Cameras are used in professional security systems and enable live video to be viewed remotely by authorized personnel. The network cameras are easily integrated into larger, complex systems, but can also function as stand-alone solutions in entry-level surveillance applications.
Network cameras can be used for surveillance of high-risk locations, such as buildings, casinos, banks and shops. Video of those areas can be monitored from relevant control rooms, at police stations and by security managers from a variety of sites.
cctv street cameras Applications for Network Cameras
Network cameras are also effective substitutes for Analogue Cameras in traditional law enforcement applications, such as keeping public places safe.
Cameras linked to access control systems such as door or barriers can enable an operator at a remote location to greet, identify, direct and authorise entry. People as well as vehicles can be recorded with time stamps that are easy to locate and review. The images can be stored in a remote location, making it impossible to steal the information.
Network cameras are easily connected to the existing IP Network and enable real-time updates of high-quality video to be accessible from any computer on the Network. Sensitive areas such as the server room, the reception area or any remote site can be closely monitored in a cost-effective and simple way, over the local network or via the Internet.
Network Cameras enable high-quality, Live Video to be shown to the whole Internet community. Live Video is an effective way to bring visitors back to a Web site.
Network Camera technology enhances Web sites thus attracting more visitors to the Web site. Weather Cameras and other Live Cameras are popular ways to boost web visitor traffic. Cameras can be mounted in a city centre, at a university, on a mountain, or by the sea to show Live Video.
IP CCTV cameras and other products are remarkably versatile and can be used in a wide range of environments, delivering benefits at many levels. Check out some of the most popular applications below:
Network cameras enhance the monitoring of a retail location by ensuring that everything is in good order. As a business owner or manager, you can monitor your site (or several sites) from wherever you are in the world. Knowing they are being monitored keeps staff on their toes and you can check in to keep tabs on what is happening at any time. Placed over a service desk or counter, you can see and hear your staff / customer interactions making monitoring customer service easy and objective. You can use the system to identify problem areas in service / staff behaviour, or to highlight best practice.
A Network camera is a convenient way to monitor the office. Areas like the reception area and conference rooms can be monitored for activity. In addition, users can keep track of who has been in the server room and take appropriate action when problems arise.
Premises such as multiple-occupier offices can be linked to a central reception area. A camera linked to an access controlsystem (at its simplest, a door or gate) can be controlled from your desk to enable you to greet, check, direct and authorise and admit visitors, without moving from your chair!
Network cameras can be used in the manufacturing industry to monitor robots, other machines and production lines from the office or home and allow service engineers to access the cameras remotely. With Pan Tilt Zoom Cameras it is possible to look at all-inclusive or detailed views.

A pioneering software product, XRAI Glass, enriches conversations for millions of people worldwide with hearing loss. XRAI, a British software company, launched the smart AI glasses in the public preview of its revolutionary technology in partnership with AR (for hardware). In this video at WION, Simon Marks shares this much-needed innovation for people with hearing loss. AI glasses are intuitive and easy to use, and they may prove to be a powerful tool for easing social isolation for people with hearing loss.
Using smart glasses tethered to a phone, users can read a person’s speech in real-time via closed captioning. With XRAI Glass, audio is converted into subtitles displayed on the glasses screen. With its sophisticated voice recognition capabilities, the software can identify who is speaking and translate languages, voice tones, accents, and pitch. John Feldman, born with profound auditory impairment, tested the glasses and described them as ‘quite extraordinary.’ XRAI AR glass still has hiccups understanding messages when two or more voices overlap and needs a quiet setting to caption the speech accurately. However, this is a huge leap towards empowering people with hearing loss.


Office Sound Masking
- Reduce Noise Distractions
- Increase Focus + Productivity
- Protect Private Conversations
Sound Masking Systems
Sound masking is the process of adding a low level, unobtrusive background sound to an environment to reduce the intelligibility of human speech and reduce noise distractions in that environment. Adding noise to the acoustic environment to make a workplace less noisy seems counterintuitive. However, speakers emitting background noise on the same curve as human speech achieves this quieting effect by dampening the sounds of speech originating from outside the “radius” of the speaker. Think about what grabs your attention: it’s rarely the volume or direction of a distraction, it’s the intelligible content of the noise. When speech is more difficult to comprehend, it’s just another unregistered background noise.
What does sound masking sound like?
If deployed properly sound masking should be barely noticeable and sound similar to the sound of gentle airflow. Generally it should blend into the background of a workplace and contribute to workplace’s general ambiance. Contrary to some misconceptions, sound masking is not “white noise.” White noise’s frequency is actually something that, when amplified, would be extremely unpleasant to listen to (think of a radio station playing nothing but static).


Traditional phone systems have ruled the business world in the past and were considered necessary tools for communication between employees and with customers. However, this has changed significantly, with virtual phone systems being the favored option now. Despite the changes, a lot of businesses refuse to see the benefits of using a virtual phone system in comparison with a traditional phone system. This could largely be because traditional phone systems are deeply rooted in many already established businesses, and a lot of older employees may not agree with the change. However, virtual phone systems do present a lot of opportunities for businesses which are not found with traditional phone systems. This article will aim to provide the differences between virtual phone systems and traditional phone systems.
Calling and receiving calls
With a traditional phone system, calling and receiving calls is done through the hardware installed. Numbers are pressed and the handset needs to be picked up. With call forwarding, a combination is needed to be input in order to do so. This can often mean that employees must remember number combinations for their fellow employees, and in doing so they can forward the call. With virtual phone systems, everything is set up visually on a platform. You can make and receive calls through a computer, and if a call needs to be forwarded, you can simply find the employee contact and press it.
Automated messaging systems
With traditional phone systems, voicemails can be set up to play if no one picks up the phone to inform the customer calling. However, that is about as far as its functionality goes. With a virtual phone system, you can of course set up a voicemail, however you are also able to set up automated messaging systems which can direct customers to the correct employee. This can mean a customer can press buttons to answer questions or even use their voice to do so, saving time and directing them where they need to go.
Scalability is important for any business, especially one that is in its growing stages. With traditional phone systems, to scale up, the business must buy new hardware and pay a technician to install it into a building or similar environment. This can end up being costly, and the business will be set back a bit. With virtual phone systems, they usually go by subscription plans based on number of users. When a business needs to increase these users, they simply upgrade to a higher cost plan which will allow for further users and thereby better communication.
With this comparison, you can see that virtual phone systems completely outweigh traditional phone systems in terms of benefits. It would be wise for any business to consider the use of virtual phone systems over traditional phone systems due to the increased functionality and the many benefits it brings. It is also an easy transition and will not halt the operation of a business for long at all.


Understanding Signal Flow in Home Recording
In the world of home recording, understanding signal flow is crucial for achieving high-quality recordings. Proper signal flow ensures that your audio signals pass through your equipment optimally, resulting in clean and professional-sounding recordings. In this article, we will explore the fundamentals of signal flow in home recording and provide practical tips to set up your signal chain effectively.
Source to Recording Device:
The journey of an audio signal begins at the source, which could be a microphone or instrument. The signal is then captured by an audio interface or mixer, which converts the analog signal into a digital format that can be processed by your computer.
Maintaining proper gain staging throughout your signal flow is essential for avoiding noise, distortion, and clipping. Set appropriate input levels on your microphone or instrument, ensuring a healthy signal without overloading the preamps. Adjust the input gain on your audio interface or mixer to optimize the signal level going into your recording software.
Impedance matching is crucial for preserving signal integrity. Ensure that the output impedance of your source device matches the input impedance of your recording device to avoid signal degradation. For example, if you're using a dynamic microphone with a low output impedance, connect it to an input with a suitable low input impedance.
Balanced vs. Unbalanced Connections:
Balanced connections are preferred over unbalanced connections for longer cable runs, as they provide better noise rejection. XLR cables are commonly used for balanced connections, while TRS and TS cables are used for unbalanced connections. Whenever possible, use balanced connections to minimize interference and maintain signal quality.
Patching and Routing:
Understanding how to patch and route your signals is important for managing multiple sources and destinations. Use your audio interface or mixer's routing options to send specific signals to different tracks in your recording software. This allows for flexible recording and monitoring setups.
Monitoring and Playback:
Consider your monitoring setup and ensure that you can hear the playback of your recorded tracks accurately. Connect your studio monitors or headphones to the appropriate outputs on your audio interface or mixer. Adjust the monitor level to a comfortable listening volume without overloading the speakers or causing ear fatigue.
By understanding and optimizing signal flow in your home recording setup, you can achieve clean, noise-free, and professional-sounding recordings. Remember to pay attention to gain staging, impedance matching, and utilizing balanced connections where possible. Proper signal flow management sets a strong foundation for the rest of your recording process.


AirPods are seen as a revolutionary product by many. Introduced in December of 2016, AirPods have been touted as an able to “free” users from wires and hassle that come with most other earbuds.
The Airpods microphone is one of the reasons why people love these earbuds so much. It provides clear communication between the user and whoever they are talking to on their iPhone or iPad, which is more than can be said for most other wireless headsets on the market.
Users can still make phone calls or FaceTime video calls without any issues or problems with the AirPods microphone. Although this isn’t what they were designed for, it does work well for this purpose.
How Can You Troubleshoot or Fix the Airpod Mic Issue?
One of the most common troubleshooting tips is to turn off Bluetooth on your iOS device and then turn it back on.
If this does not work, try opening the AirPods case near your iOS device. This should have Bluetooth turned on, which will help the AirPods connect to your device.
You can also try restarting your iPhone by pressing and holding down both the Home button and Power button for 10 seconds.
The Airpod mic can be a problem for some people. Here are some ways to troubleshoot the issue:
– Try to change the position of your Airpod in your ear.
– Try to have a conversation in a noisy environment so you can see if the mic is registering any sound.
– The battery might be low, try changing the battery and see if that fixes it.
– If this doesn’t work, contact Apple Support for assistance.
What are the Common Causes of the Airpod Mic Issue?
AirPods are Apple’s wireless earphones that have been designed to use the company’s new W1 chip. The AirPods are small, lightweight and designed to be worn in either ear. When the AirPods are not in use, they are stored in a carrying case which can wirelessly charge them. The AirPods have one of the most advanced wireless technologies- Bluetooth 4.2
There are several reasons why someone might experience microphone problems with their Airpods, but they all come down to one thing: interference with other devices and/or WiFi networks.
What are the Solutions for AirPods Mic Not Working on iPhone XR?
Despite the fact that AirPods are excellent wireless headphones, things don’t always go smoothly when you try to use them with your iPhone XR.
In this article, we will be discussing what solutions there are for AirPods mic not working on your iPhone XR and how you can get it to work.
The first solution, which is the most popular one, is by resetting your device. This is a quick and easy solution that has been known to work on most occasions. You should reset your phone in order for the microphone issue to be resolved.
Another alternative solution is by restoring from a backup of your device that was made before you updated it with iOS 12.
What is Apple’s Official Response About the Airpod Mic Issue?
Apple has officially responded to the recent issue about the AirPods mic cuts out after a few seconds of use. Apple stated that they are aware of this issue and will be releasing a software update in the coming weeks to address the problem.
In an interview with blingdot.com, an Apple spokesperson said: “We’re aware of this and we have identified a fix that will be released in a software update soon.”
The AirPod mic cuts out after a few seconds of use. This is because the battery life on the new wireless headphones is quite short, which means that it is necessary for them to cut off after three minutes of usage in order to save battery life.

A new trend in the automotive field is adding a smart speaker to/in your car. As most of you already know, most newer cars come equipped with an integrated voice assistant. However, these usually only control specific automotive functions such as climate control and navigation. What I will be discussing below are the pro’s and con’s of adding an Alexa or Google smart speaker. (Hopefully, the industry will produce smart automotive speakers capable of accessing multiple platforms).
An integrated smart speaker would be considered by most redundant if you currently have Apple CarPlay or Google Android built-in to your car stereo. Most would consider Apple’s Siri the least accurate so the addition of Alexa or Google should be considered. If you currently use your smartphone as a smart speaker, the addition of a dedicated smart speaker will provide louder/clearer interaction, but the addition will take up space. Mounting/position of the devices should be taken into consideration. A benefit is the fact that these devices (usually) connect to your car’s power supply and don’t need to be charged. SAFETY is always paramount!
First, the connection: Bluetooth or wired. Although wireless connections via Bluetooth seem to work well, I always prefer a wired connection. This eliminates connection loss which we all have experienced at one time or another: probably with wireless/Bluetooth earbuds.
Even though a wired connection takes an extra step, I’d argue that this is a small price to pay for a consistent connection and little or no inconvenience afterwards since all communication will take place “hands-free”.
(image credit – businessinsider.com)
Second, the platform. As is the past, I would recommend sticking with the ecosystem you currently use since you will be accessing data such as contact addresses, phone numbers and your calendar.
If you have an older car with limited technology, a smart speaker can be a great way to add hands-free interaction in an affordable manner with options starting under $100.
Also consider DATA FEES, all smart speakers need to connect to the internet. This will usually be through your smartphone and can use up data quickly if you don’t have an unlimited cellular plan.
Technology, especially smart speakers seem to be everywhere. Security should also be considered since no one knows for sure how these “always listening/ potentially always recording” devices can be used (against) you. Also, be sure to check your local and state laws regarding the use of such devices during driving. It seems like everything is being recorded: video and audio! But that’s a story for another time.
Finally, DISTRACTION! Adding a smart speaker to your car, especially if your car already has a voice assistant, can be a huge distraction. I always use hands free communication when driving BUT still find myself, at times, “in-another-world”. Perhaps a better course of action would be to dis-connect (almost) entirely from the outside world and enjoy your drive. Another option is to pull over to take care of your business/communication. This would be safer, more enjoyable and definitely less stressful!

Enable CDP on ESXi host using PowerCLI
Adding new VLANs to ESXi hosts becomes very hard if the location of the host NICs are not properly documented on the physical switch. In order to make things easier, below is a powershell script to enable CDP on a standard vSwitch. Enabling CDP will show the hostname of the ESXi host as a neighbour to the physical switch and the ports they are connected to.


Comparison of Wire and Cable
Do you think wire and cable are the same type of product? Maybe your answer is "yes", but in fact they are completely different.
Wire and cable are terms that are often used in the electrical and communications fields. However, people often confuse these two terms because they look similar。
The difference between wire and cable
The basic difference between wire and cable is that a wire is a conductor, while a cable is a set of conductors. While these conductors are made of common materials copper or aluminum. Usually, these wires are bare and stranded together. However, some wires are covered with a thin layer of PVC. In the case of cables, they would extend parallel and twist together to form a box. For safety reasons, inner sleeves and jackets are manufactured.
The "wire" in the wire and cable your way
This wire is measured in diameter. Depending on the diameter of the wire, it is measured with the wire gauge number. The smaller the gauge number, the thicker the wire. The ideal size for residential applications is 10 to 20，For example: 10 gauge wire, 14 gauge wire, etc. However, keep in mind that larger wires carry more current and may damage household appliances due to fuse blowing.
The "cable" in the wire and cable your way
The cable consists of a heat-generating wire that carries current, a zero wire to form a loop, and a ground wire. Cables are classified by total number of wires and gauge.
Wires are used to carry electricity, carry mechanical loads, and transmit telecommunication signals to heated jewelry, clothing, automobiles, or any industrially manufactured parts such as pins, bulbs, and needles.
Cables are used for electric power transmission, telecommunication signals or power transmission.
Types of wire and cable
1. solid wire solid wire has only one conductor, is insulated or bare and is usually protected by a colored sheath. This type of wire has a very low resistance and is best used at higher frequencies.
2. Standard wire consists of many thin wires twisted together. These wires are used where flexibility is needed and standard wires can be used for a long time. Conversely, the cross-sectional area of a standard wire is larger than that of a solid wire.
1. twisted pair twisted pair cable consists of 2 pairs of twisted wires. This distortion avoids the noise generated by magnetic coupling and can therefore be used for the transmission of signals. Twisted pair cables are commonly used for data communications and telecommunications.
2. Multi-core cable - Cable has 2 or more insulated conductors and is designed to protect the integrity of the signal. Both twisted pair and multi-core cables are called balanced cables.
3. Coaxial Cable - Coaxial cable has an inner conductor surrounded by parallel outer foil conductors, which are protected by an insulating layer. In the cable, the two conductors are separated from each other by an insulating medium. These cables are usually used for television cables because they are more stable than twisted pair cables.
4. Optical cable - Optical cable transmits signals through a bunch of glass wires. They have a larger bandwidth than metal conductors, which means they can transmit more information and data. Therefore, optical cables are used instead of traditional copper cables.


Network / LAN
LAN / Network is the backbone of every Office / Business today. Various departments of the Office are connected with the Local Area Network.
Companies and Offices small and big run their important software's like Accounting, Billing, ERP, MIS and over the network. Also critical data is shared between executives through the network shares for collaborative projects.
Internet has also become very essential for day to day work for all departments, so more and more nodes are given Internet access.
Today, Viruses and worms are network aware. If even a single node on the LAN is infected the worm will rapidly spread to all the nodes of the network like fire and bring down all the PCs in a very short time. Also spyware and malwares disrupt the network access between nodes and stops all communication.
Net Protector AntiVirus for networks incorporates protection features for Enterprise and Corporate Networks.
Net protector protects each node individually and also communicates and reports to a central server. So any network epidemic is stopped from spreading.

How Can We Make Free Calling On Mobile
If you are like most people, you probably use your cell phone for just about everything. You use it to stay connected with family and friends, to work, and to play. But did you know that you can also use your cell phone to make free calls?
There are a few different ways that you can make free calls on your cell phone. One way is to use a VoIP service. VoIP stands for Voice over Internet Protocol, and it allows you to make calls using the internet instead of your cell phone minutes. There are a few different VoIP services that you can use, and most of them are free.
Apps that Allow a Free Call Between Cell Phones
There are a few apps that allow you to make free calls between cell phones. Here are some of the most popular ones:
– Facebook Messenger
– Google Hangouts
Companies and Countries Attempting to Block Free Mobile to Mobile Calls
As mobile phone usage has become more widespread, so too has the practice of making free calls between mobile phones. However, there are a number of companies and countries that are now attempting to block these calls.
The most common reason given for attempting to block free mobile to mobile calls is that it is perceived as a threat to the existing revenue model for mobile phone services. In many cases, mobile phone users are charged for each minute of calling time, and so free calls between mobile phones


Technology Trend #2: Mobile Devices Stage Fast Growth. The age of desktop computers is going the way of the dinosaurs. Just like in earth’s evolution millions of years ago, a similar Cambrian explosion has occurred with mobile technology. Most individuals think of smart phones when they hear mobile devices. The mobile device market is much larger than that. The first mobile mammals emerged as smart phones and they’ve already spawned a vast evolutionary tree that now includes iPads, Nooks and many other mobile devices. Just how big is this growth? IDC reported worldwide mobile phone market grew nearly 20% through the first quarter of 2011. Nokia still holds the dominant market position with 29% market share, Samsung is #2, LG is #3 and Apple holds the #4 spot with nearly 115% annual growth and a 5% market share. Additionally, IDC reports 173 million smart phones were sold in 2009 and 269 million in 2010. Half a billion smart phone sales in 2011 might not be unreasonable.
This trend will have two significant implications for brokers and agents:
- Mobile devices will foster significant innovation for how real estate services will be delivered, often in ways we currently can’t predict. Example: Apple sold 15 million iPads in 2010. These sales vastly exceeded Apple’s internal projections along with many industry analysts. Even “industry insiders” and those “in the know” did not accurately predict the iPad’s rapid growth. (1)
- Business models will rapidly evolve for mobile applications. Currently, many mobile applications are available for a nominal up-front charge with little-to-no technical support. ( Technical support for mobile applications today often means send an email and you hope to get a response back…) As more useful functionality is performed on mobile devices, pay-as-you-go business models will be introduced where customers will be charged a monthly fee to use the application. More robust technical support will also be available (i.e. telephone, chat, etc.). Customers will pay these charges because the value provided by these future applications will be far greater than currently available in many of today’s mobile applications.
Summary: MRIS expects this established trend to continue. Mobile devices will become a dominant computing platform in the real estate industry. While desktop computers will still provide essential services, savvy brokers and agents will need to adopt and provide services that operate on mobile devices to reflect the evolving demands of their customers. Please see our upcoming MRIS TV show for an in-depth discussion of this trend.
