In today’s digitally connected world, securing your network is more critical than ever. From personal data to sensitive business information, network store a wealth of valuable data requires protection. Most of our daily functions of society rely on digital network and infrastructure. Everything from methods of communication, financial transactions, healthcare access and transportation has been revolutionized by advancements in technology. So, with the rapidly evolving cyber threats, safeguarding our network and infrastructure is not just an option but a necessity.
Understanding Network Security
Understanding the fundamentals of network security is essential for individuals and organizations alike. Network Security stands as a critical pillar in safeguarding sensitive information and maintaining the integrity of communication channels.
what is Network Security?
Network Security refers to the practice of protecting the computer networks and network infrastructure from unauthorized access, misuse, modification, or denial of service. It encompasses a range of technologies, processes, and policies designed to defend networks and the data they transmit against cyber threats.
Network security is a multi-layered approach, employing various tools and techniques to safeguard your network from unauthorized access, data breaches, and malicious attacks.
Here’s a breakdown of some of the most common types of network security:
- Network Access Control (NAC): NAC solutions manage and restrict access to a network. They ensure that only authorized device can connect, further strengthening your network’s perimeter.
- Intrusion Detection and Prevention system (IDS/IPS): These systems monitor network traffic for suspicious activity and can block potential attacks in real-time.
- Data Loss Prevention (DLP): DLP solutions help prevent sensitive data from being leaked or stolen, either accidentally or intentionally.
- Vulnerability Scanning: Regular Vulnerability scans can identify weaknesses in your network security posture, allowing you to address them before they can be exploited.
Basic steps on How to secure a network
Securing a network involves implementing various measures to protect it from unauthorized access, data breaches, and cyber threats. Here are some basic steps you can take to enhance the security of your network:
- Assessment and Inventory: Start by assessing your network infrastructure and taking an inventory of all devices, software, and services connected to it. Identify vulnerabilities, outdated software, and potential weak points that could be exploited by attackers.
- Firewall Configuration: Install and configure firewalls to control incoming and outgoing traffic based on predetermined security rules. Ensure that firewalls are properly configured to filter both inbound and outbound traffic and to block unauthorized access attempts.
- Network Segmentation: Divide your network into smaller segments or subnetworks to limit the spread of cyber threats. Implementing network segmentation helps contain breaches and prevents attackers from accessing sensitive resources by compartmentalizing the network.
- Access Control: Implement strong authentication mechanisms, such as multi-factor authentication (MFA), to verify the identities of users and devices accessing the network. Enforce the principle of least principle of least privilege, granting users and devices only the minimum level of access required to perform their tasks.
- Encryption: Encrypt data transmission and storage to prevent unauthorized access and eavesdropping. Utilize encryption protocol such as SSL/TLS for securing data in transit and tools like BitLocker or File Vault for encrypting data at rest.
- Regular Software Updates: Keep all software, including operating systems, applications, and network devices, up to date with the latest security patches and firmware updates. Vulnerabilities in outdated software are a common entry point for attackers.
- Network Monitoring: Deploy Network monitoring tools to continuously monitor network traffic for suspicious activities or anomalies. Intrusion Detection and Prevention Systems (IDS/IPS) can help detect and mitigate potential threats in real-time.
- Employee Training: Educate employees about cybersecurity best practices, such as recognizing phishing attempts, creating strong passwords, and avoiding suspicious links or attachments. Human error remains one of the biggest security risks, so ensuring that employees are aware of potential threats is essential.
Securing your network is a continuous process that requires diligence and proactive measures. By following and implementing these basic steps outlined above and understanding the various types of network, you can significantly enhance your network’s defenses against cyber threats.
Remember, network security is not just about protecting data; it’s about protecting your business, your customers, and your reputation. Stay informed, stay vigilant, and prioritize the security of your network at all times.

Apologies to wine enthusiasts – normal service will be restored as soon as possible – but this is an update to my 2012 post: Replacing a BT landline by VoIP. In brief, I have been and gone and done it.
After the flurry of activity back in 2012, there were several years of inaction, as I was a bit nervous about committing to VoIP, and my wife was not totally happy with VoIP line quality. We continued to have phones connected via Sipgate and Voipfone, but only used them occasionally, and for outgoing calls only.
However there were a number of technical innovations in the Slatcher household. Not least, I was dragged screaming and kicking into the 21st century, and got myself a smartphone. This was significant because it meant I could call using VoIP also on my mobile, using the Zoiper app. And eventually, I moved from PAYG to unlimited UK calls for a small monthy charge, which made my landline even more redundant. In the meantime, my Virgin broadband speeds got faster and faster, and I ditched my old separate router to enable me to fully use that speed. Without the old router, my ATA stopped working, and at first I couldn’t be bothered to work out how to reconfigure it, so I had a cathartic clearing out of the rats-nest of redundant cables, boxes and phones. The ATA was moth-balled, and VoIP was Zoiper-only for a while. But even though I was using it less and less, my landline provider (no longer BT) kept ratcheting up the line rental charges, so something had to be done.
A few months ago I resurrected my ATA, plugging it directly into my Virgin Hub 3.0 modem/router. It turned out to be not too difficult to get it working again with both Sipgate and Voipfone. When I looked afresh at the deals and service offered by those two companies, it seemed that their pros and cons were still pretty much as they were back in 2012. Voipfone would have been more expensive, with small monthly charges for a ported landline and multiple registrations, but it had excellent phone support. While Sipgate had no recurring charges for the same features, but support, while adequate, was email-only. As I was by then less dependent on my old landline number working, I decided I could live with email support, and chose Sipgate as my main VoIP service provider – it was the one destined to host my old landline number, and to be the one hooked up to the main set of household phones.
The number porting went smoothly, so now the deed is done and everything is hunky-dory. The multiple registrations are a great feature, and mean that when someone calls our old landline number all the household phones ring, and also Zoiper on both our mobile phones. I also very much like the Sipgate voicemail system. All messages are emailed to me as mp3 attachements, which is so much handier than having to negotiate an answering machine or phone-based voicemail.
So far, so good.


If you are a big social media fan, there is good chance that you have probably used Skype or at least heard of it. Skype is an online application that allows users to video chat and use voice call services. For instance, users can share documents, texts, and videos with other online users. Individuals can also take advantage of the video conference call, where you can actually see the people that you are talking to.
In 2003, two software writers that had previously worked on the file sharing software known as Kazaa launched Skype. For those individuals that don’t remember Kazaa was a peer-to-peer file sharing program that go its start in the early 2000s. Kazaa became popular right around the time that Napster was getting sued and shut down for illegal file sharing. Kazaa allowed people to share music files, but what made it different is that users could share videos and programs, which made it extremely popular throughout the community.
The basic theory of a peer-to-peer network is that whoever is on the network is connected to everyone else on that network. This means that there is no central server or server groups that holds all the files. The more people that had the same file or video on their computer enabled others users to download that same file or video much faster. For instance, if you were downloading a music file that 10,000 other people had on their computers it would download much faster. If you wanted download a music files that only 1,000 people had on their computers, it would download much slower.
Skype takes advantage of this peer-to-peer networking technology, but it incorporates it into voice transmission rather than downloading. The whole theory is, the more people that use the service the more reliable and stable the connection will be. Along with the fact that it was free and available to all users this really helped promote Skype. Individuals could make free voice to anywhere in the world from anywhere in the world for free.
Skype has long been noted for its easy to use interface right from the initial launch. Skype works in the same manner that other instant messaging programs work. While the technology behind the curtain is quite complicated the user interface is very simple and easy to understand. To start off, all you have to do is download the appropriate Skype application for the device that you are using. After you installed the software, you will be prompted to create an account where you will choose a unique username and password. After this you just add contacts and make a make a call.
Skype offers a variety of unique features to users. One of the most popular among the many features is the instant messaging and char history. Users can send instant messages to anyone that is on their contact list. Even messages that are sent when the user is offline, will be received immediately when the offline user logs back in. The Skype servers also keep track of any messages that are sent for up to 30 days, so you can always go back and view your chat history.

Calls made on Telstra public payphones will soon be free Australia-wide, under a new initiative announced today by the telecommunications company.
Currently, there are 15,000 Telstra payphones located across the country, often found on street corners, in rural towns and outside airports and supermarkets. Now instead of scrambling for loose change to make a call, you’ll be able to ring nationwide free of charge. Calls to international numbers will still incur a fee.
The ubiquitous presence of the bright pink and orange Telstra payphones has long been ingrained in Australia’s landscape. However, as mobile phones became universal the use of public payphones dwindled.
While some Australians may consider telephone boxes a relic of the past, they are still a vital line of communication for vulnerable Australians, whether they be fleeing a natural disaster, escaping domestic violence or experiencing homelessness.
“I’ve seen myself how much payphones are part of the fabric of Australia and how important they are in good times, and bad,” said Telstra CEO Andrew Penn in a statement this morning.
“I’ve seen queues of people waiting in line, coins at the ready, to use a payphone to call home and tell their family and friends they’re safe after a bushfire, a cyclone or some other natural disaster has taken the mobile network down.”
Last year, 11 million calls were made on public payphones in Australia, with over 230,000 of them being to vital support services and triple zero. Penn hopes that by making payphones free to use, they can continue being the crucial lifeline that they are.
“We want to contribute to a better, more caring and more inclusive Australia, an Australia where people can reach out for help if and when they need to, or just connect if they feel like it,” said Penn.
“I’m delighted it’s now free for everyone to make calls anywhere in Australia.”

High-Power Microwave Amplifiers
Mainstream recently completed a highly successful project to demonstrate the benefits of spray cooling high-power microwave amplifiers (device-level) used in solid-state, phased array transmitters/receivers. Heat flux removal rates in excess of 100 W/cm2 were achieved at wall superheats less than 12 K, using inert, dielectric refrigerants. Amplifier output power was increased by 37%, and efficiency was increased by 14%. Although these results are significant in laying the groundwork for an integrated spray cooling system for phased array antennas, additional work must be performed to optimize the spray system and increase reliability of the thermal/electrical system.
Mainstream engineers, along with our commercial radar partner, are working to demonstrate the benefits of spray cooling a multi-channel transmitter (module-level). Based on prior experimental work, we expect a 40% increase in power output, a 30% increase in efficiency, and an order of magnitude increase in reliability.
This enabling thermal technology has immediate application to MDAs Medium Extended Air Defense, Theater High Altitude Area Defense, Ground-Based Midcourse Defense, Sea-Based Midcourse Defense, and Advanced Concepts Programs. In addition, the technology can be extended to other high-heat, flux-cooling applications, including MDAs Airborne Laser, Space-Based Laser and Kinetic Energy Laser Programs.
Industrial-sized, solid-state lasers cannot be scaled up in power to meet the demands of future missile defense systems due to stringent thermal constraints. Existing water-based thermal management systems are undesirable because water has a high freezing point and the military systems need to operate in low-temperature environments.
Mainstream recently verified experimentally the potential for spray cooling high-power laser diode arrays with non-water-based fluids. This patented system is capable of removing high heat flux at the laser diode array, maintaining a spatially uniform temperature over large laser slab surface areas, and accurately controlling laser temperature.
A complete spray cooling thermal management system is now being designed, fabricated, and integrated into a high-power, solid-state laser. Next, the performance of the integrated laser system will be tested. Gravity-independence will be demonstrated for adverse-gravity and space-based applications. The result of this program is not just an incremental improvement over an existing thermal solution. It is the enabling technology that will make laser defense systems a reality.

The defence ministry on Wednesday signed a Rs3,000-crore contract with New Space India Limited (NSIL), the commercial arm of Indian Space Research Organisation (ISRO), for an advanced communication satellite, GSAT 7B, for the Indian Army.This is a major boost for the Indian Army’s communication capability and to fulfill its long-standing need.
Unlike the Indian Air Force and the Indian Navy , the army currently does not have a dedicated satellite.
According to the defence ministry the satellite will considerably enhance the communication capability of the army by providing mission critical beyond line-of-sight communication to troops and formations as well as weapon and airborne platforms. The army is likely to get the satellite in 2026, the officials said.
This will be a five-tonne geostationary satellite to be developed indigenously by ISRO.
It is said that the satellite with advanced security features will support tactical communication requirements of not only troops deployed in the field ground , but also remotely piloted aircraft, air defence weapons and other mission critical and fire support platforms.

The way in which the computer is connected with each others is called Topology of network.Ti is a method to design a network is called Topology. Each Topology is suited to specific tasks and has its own advantages and disadvantage. I will also show you advantage or disadvantage of typologies.
There are two types of Connectivity
1. Point to Point:- In this type of connectivity only two two device are connected with each other.
2. Multi Point :- In this type of connectivity many devices are connected with each other.
There are 6 Types of Topology
1. Bus Topology
2. Star Topology
3. Ring Topology
4. Tree Topology
5. Mesh Topology
6. Hybrid Topology
1. BUS TOPOLOGY :- Bus Topology is a simplest physical topology. A bus topology consists of single cable that runs to every work station. In this method when one computer send the information(Signal up & down) to the another computer through wire, all the computer on the network receive the information but only one (The one with the address that matches second computer) accept the information. Only one computer at a time can send a massage . when one computer can be significantly affect the speed of the network. when one computer sending information wait all another computer but this time is vary less that is why the user cannot relies it.Another important issue on that network is termination. In bus network information can be travel the entire length of cable. So the termination are used at the end of the cable.
In the bus topology we used Co-axial cable and BNC Connector
- Advantage of Bus Topology :- . This bus is simple very small network and easy to use easy to understand. It is easy to extend a bus.two cable is joint in to one longer cable and allowing more to join the network.Its easy to install.
- Disadvantage of bus topology :- Problem finding is difficult AND difficult to troubleshooting. Each barrel connection weakness the electrical signal.
2. STAR Topology :- In a star Topology all computer are connected with a central device just like hub, switch .a cable is run from each computer to the hub/switch. In this topology when a computer sends data, the data will be transmit to all computer connection through hubs. The method of data transmission in this topology are broad casting UTP cable are use in this topology and rj45 connection are used. star topology is more expensive because its need more cable means each cable for each pc.
- Advantage of star Topology :- Star Topology is easy to expend and its vary easy to troubleshoot. Its easy to add new computer on star topology .You simply run a new line from the computer to the central located and plus to the HUB or switch. If in this topology a single computer is dose not work your full network is working properly.
- Disadvantage OF STAR Topology :- If the central device hub or switch is fail to work your all network is fail to work . In this topology required more cables its is more cost.
3. RING TOPOLOGY :- In this topology every computer is connected to the next computer in the ring. The massage flow around the ring in one direction each computer re-transmits what is receives. A ring is an active network and it is not subjected to the signal loss problem a bus experiences there is no transmission because there is no end to the ring.
In this topology all computer is connected to each other as like a ring.each device has only two neighbor for communication purpose. data travles through many point before reaching the destination but physically they are always connected with each device with a center lies device is called M.A.U (Multi access point)
- Advantage of Star Topology :- It use less amount of cable for network, because every computer is given equal access to the taken no one computer can monopolize the network.
- Disadvantage of Ring Topology :- Failure of one computer on the ring con-effect the whole network . It is difficult to troubleshoot a ring topology. If we add or remove computer in ring topology it is disturb to all network in this Topology.
4. TREE TOPOLOGY :- In this Topology Multi pal star network are connected according to the star topology. all devices are connected with center lies device like hub or switch.
5 MESH TOPOLOGY :- In the Mesh Topology each device has point to point connected to every device on the network.In this topology each device is connected to every other computer. In this topology any device can send data to ant device into a network data send by the device can take any possible path to reach the destination .
Disadvantage of this topology its required more cables so its too expensive.
6. HYBRID TOPOLOGY :- This Topology is a communication of different network topology . It is also known as spacial topology. The start bus Topology is the most used by hybrid topology in an organization.

15 December 2023, SINGAPORE – NuSpace and Squareroot8 Technologies have successfully demonstrated a light-weight prototype of Post-Quantum Cryptography (PQC) key exchange between a nano-satellite, NuLIoN, and a Singapore Ground Station using keys generated by an on-board Quantum Random Number Generator (QRNG) chipset. This first of its kind demonstration provides a cost-effective solution to the risk of future quantum computers breaking satellite communications. This result is also a testament to the feasibility and accessibility of space-based quantum-safe communication and space-ready quantum technologies, as well as the engineering capabilities of the collaboration partnership.
At the heart of the demonstration is a single-board QRNG-PQC module that is solely responsible for the quantum-secure key generation and quantum-safe key exchange. Its small footprint on NuLIoN allows the multi-mission 3U nano-satellite to perform several other applications with its payloads. In particular, its form-factor allows the QRNG-PQC module to be deployed in other satellites while minimising engineering considerations.
With the prospect of quantum computing becoming a reality, many organisations and businesses are beginning to explore and adopt quantum-safe communication solutions. The QRNG-PQC module will posit itself uniquely as a trade-off between feasibility and security for quantum-safe satellite communications.
While quantum key distribution (QKD) via satellite is often discussed as a potential quantum-safe solution for space communications, its susceptibility to environmental factors, including light pollution and weather conditions, results in generally low key-generation rates during implementation. Consequently, it may not be the most suitable option for widespread deployment across various locations. A more practical and effective approach involves leveraging existing satellite communication technologies and post-quantum cryptography (PQC) algorithms, complemented by line-of-sight physical security measures, to ensure the security of space communications. Indeed, the implementation of PQC is considered cost-effective, with a shorter product-to-market runway and higher throughput compared to QKD implementations in space. For these reasons, PQC emerges as the preferred key exchange protocol for space communication. Furthermore, the QRNG-PQC solution not only produces quantum-secure keys reminiscent of entanglement-based QKD but also adopts quantum-safe PQC key exchange, ensuring the secure exchange of sufficient keys for practical commercial and civil applications such as IoT connectivity, remote sensing, and communications.
“The successful demonstration of the QRNG-PQC on-board NuLIoN has certainly left our footsteps on the history of commercial quantum-safe satellite communications. I am hopeful that this result will pave the way for cost-effective secure satellite communication solutions, even into the quantum era. This achievement would not have been possible without the innovation, craftmanship and grit of the team from Squareroot8 and NuSpace who has contributed to this project. Moving forward, I am confident that we will continue to enjoy a fruitful partnership with NuSpace and together, we will scale greater heights in the future as a team.”, Dr. Goh Koon Tong, Chief Executive & Co-Founder of Squareroot8 Technologies.
“I am both honoured and excited to share this remarkable achievement alongside Squareroot8 with the world. Our dedicated team of engineers and scientists have worked tirelessly to bring this revolutionary technology to fruition, and today’s success marks a significant step forward in advancing the security and capabilities of satellite communications. At NuSpace, we have always been committed to pushing the boundaries of what is possible in space technology. The successful deployment and testing of our jointly developed QRNG-PQC module is a testament to our unwavering dedication to innovation and excellence.” Mr. Ng Zhen Ning, Chief Executive & Founder of NuSpace.
Following NuLIoN’s launch, the R&D team at NuSpace and Squareroot8 are looking at improving the performance and efficiency of the QRNG-PQC module towards its productization. The next milestone for the QRNG-PQC module is its deployment in field tests for commercial applications. Interested parties who are looking to integrate quantum-safe satellite communications into their businesses are welcomed to contact NuSpace or Squareroot8.

long distance. The
communication of information to a destination outside the local calling area. Also called "long haul" traffic.


All our office computers except one had no internet connection for 3 days last week. A new cpu had been delivered and installed – a new i7 machine with Windows 7 OS. And the boss decided that the i7 machine should now be the central machine (previously, it was one of the XP machines) that will get connected to the only internet line alloted to our office, and share the connection to the rest of the office machines.
Now, all of the existing CPUs on our LAN were old ones with Windows XP as its operating system. Thus, we discovered as soon as we started fiddling with the Win7 i7’s configuration that we cannot share the internet connection the way we did before on the XPs. The Win 7 system requires that all other machines in the network should also be running Windows 7 in them. Ugh!
The easiest solution would have been to just purchase a router. Our existing gadget is just a switch, not a router. Before we tried going that way, however, we decided to call the IT guys in the adjacent department. And he fiddled and twiddled around with the i7 machine. Meeting a blank wall too, he decided to do some digging around for an appropriate software for this purpose. Thus, on the third day, he installed the Kerio Winroute application (now called Kerio Control). The Kerio Winroute software gave us the much needed internet connection without too much sweat. It was installed only on the 64-bit ‘server’ machine (there was no need to install anything on the other computers). We used a trial version. The trial expired a day ago, but the feature that shared the internet connection still works.
Me, I still think we’d still be better off with a router. That way, all computers would have internet connection even if the i7 ‘server’ machine is turned off. Also, wireless internet for laptops can be availed by anyone within the vicinity of our office.

The thing with Cherry Mobile is it takes pride in delivering high-end capabilities inside a basic and simple phone as much as possible. Their grand attempt at an Android phone, the Cherry Mobile Orbit, could easily go right up that alley.
Witness the specifics. The Orbit looks every bit like your regular smartphone, made of plastic and simple in its design and composition. It sure looks tough on the outside, for one.
The massive glass display is already a plus, since big monitors are always good for browsing. Its touchscreen feature however hasn't been very tactile, and the phone's motion sensitivity is somewhat feeble - we've definitely had better ones.
The Orbit also runs quite reliably for a phone that runs on a 528 MHz QUALCOMM processor - the ideal processor would be 600 MHz - though it shows glimpses of struggles when multiple programs are opened at the same time. Clearly, multi-tasking is not one of its strengths.
What's remarkable with the Orbit however is it can run on dual SIM smart phones simultaneously, proving that an Android OS type can somehow withstand two cellphone lines. Like any other smart phones, the Orbit has a SIM indicator whenever the user makes a call or drop an SMS.
We found the Orbit's little specs to be fairly inclined on the impressive side. It can handle Wi-Fi spot functionality without showing signs of hitches, has decently loud speakers, and it owns a 5 mega pixel camera with an auto focus and a decent flash. And hey, it runs Angry Birds pretty well too.
But then again there's the occasional small-time downside - the 3G feature only applies to SIM 1, while you'll have to make good with the GPRS/EDGE data on SIM 2. It also seems to have a hard time running any Flash content on the web browser, but we figure it's the low processor. Some would also say it runs on a pretty short battery life. Like we said - small time downside.
Priced at Php 12,990, the Cherry Mobile Orbit makes for an affordable Android unit notwithstanding the shortcomings it might have. Sure, it's not the cheapest Android out there but it packs more extras and it functions just the way it should for a dual SIM phone. Catch a few hampering here and there, but an overall winning choice duly suited for the Cherry Mobile market.

This data is analyzed to gain valuable insights and make informed decisions regarding energy distribution and consumption.
Optimizing Energy Distribution
One of the major advantages of smart grids powered by IoT technology is the ability to optimize energy distribution. Real-time data provided by IoT devices helps utility companies identify areas of high demand and adjust electricity flow accordingly. This dynamic control ensures that electricity is efficiently distributed to areas in need, reducing power outages and improving overall grid reliability.
Enhancing Energy Consumption
IoT technology also empowers consumers to make smarter decisions about their energy consumption. With IoT-enabled devices in their homes, consumers can monitor their energy usage in real-time and identify opportunities for energy efficiency. For example, smart thermostats can adjust temperature settings based on occupancy or weather conditions, reducing energy waste and ultimately lowering utility bills.
Benefits of IoT-enabled Smart Grids
The integration of IoT technology into smart grids offers several benefits:
Improved grid efficiency and reliability
Reduced energy losses and wastage
Enhanced visibility and control over energy consumption
Greater integration of renewable energy sources
Cost savings for utility companies and consumers
IoT technology has revolutionized the concept of smart grids, enabling optimized energy distribution and consumption. With the ability to collect and analyze real-time data, smart grids powered by IoT offer numerous benefits for utility companies and consumers alike. From improving grid reliability to reducing energy waste, the integration of IoT technology in smart grids is paving the way for a more sustainable and efficient energy future.Thank you for reading!

Xona Space Systems – 23 June
Xona Space Systems
Xona Space Systems is developing a new generation of high-accuracy position, navigation, and timing (PNT) solutions for intelligent systems. Delivered via a secure, high-power signal from low Earth orbit, the Pulsar™ service from Xona aims to enable the next wave of connected technology.
In North America alone, over $300 billion of economic impact per year relies on Global Navigation Satellite Systems (GNSS), yet the only signals available to the public are unprotected, limited in precision, and susceptible to disruption from easily obtainable jammers and spoofers. The reliability and performance of satellite navigation needs to drastically increase to support modern industries such as autonomous vehicles, aerial mobility, maritime automation, and many more.
Xona Space Systems is developing the secure and precise PNT service that will enable modern intelligent systems to operate safely at scale.
Xona has been working hard to grow the company and in the past year has expanded their operation to include offices in Vancouver, Canada and London, England, along with their headquarters in San Mateo, California.
On the product side of things, the Xona Pulsar LEO navigation service is complementary to other localization technologies being used by autonomous vehicles. LiDAR and computer vision techniques can achieve accuracy needs, but can struggle to meet safety requirements due to degraded performance in inclement weather and in sparse environments. Satellite navigation can offer a lightweight and low-cost localization solution to end users that is unaffected by weather, uses a universal and consistent coordinate system, and high performance in sparse operating environments where relative localization technologies can struggle. Existing GNSS faces threats from RF interference and spoofing. With Xona’s Pulsar LEO navigation service, these provide another step on the road to safe and secure autonomy.

If you are looking for new hearing aids, there are many options to consider. The function of your hearing aids is an essential factor when making the decision, but so is style and comfort. You should consider three modern features that all hearing aid users think of when buying their next set of devices:
Remote controls allow you to adjust your device from a distance. For example, you can control the volume, change programs, or turn off and on your hearing aid without having to touch it. Nowadays, many devices have wireless and wired options for remote controls, depending on what works best for you.
You can control some hearing aids with your cell phone or tablet. You could also consider pairing your remote with an app. The “Hear” app is one example of how you can use technology to control your hearing aid from any distance.
Wireless And Bluetooth Connectivity
The wireless connectivity will allow you to connect your hearing aids directly to a Bluetooth-compatible device, such as a smartphone. It will enable the user complete control over their devices while not being limited by wires. It is beneficial because if you have a phone call, you can take all your calls on speakerphone, just like on a landline.
You can make calls on speakerphones, and you’ll still be able to hear the other person because your hearing aids will pick up their voice through the microphone. The wireless connectivity also means that you don’t have to get up every time something happens in another room – like if someone knocks at the door or a phone call.
You can control your hearing aids with a smartphone, which is very convenient. For example, with an app for iPhone or Android smartphones, you’ll be able to adjust the volume that way if it’s too loud in certain places like at work or on public transportation.
You’ll also be able to choose from different types of programs and settings depending on what you’re doing. It makes it easy to switch between various programs depending on your surroundings. You don’t have to worry about battery life either because these devices are rechargeable, reducing the number of times you need to change batteries over time.
With Bluetooth connectivity, users can take phone calls directly through their hearing aids via a compatible smartphone. It is convenient because it allows users to take calls on speakerphones just like they would with a landline phone, and the hearing aids will still pick up the other person’s voice through the microphone.
Self-learning, vertical or horizontal directional microphones are two famous examples of self-learning features. They allow the hearing aid to adjust its settings based on what sounds it hears in your environment. If you prefer specific frequencies over others, this is an excellent feature for customizing sound. For example, it helps filter out background noise while amplifying clear voices that you want to hear.
The more you wear your hearing aids, the more information it gathers about how they are working for you. It means that over time, the technology will continue to improve as well!
Hearing aids have come a long way since the bulky, uncomfortable devices of the past. They now offer high-quality sound and convenience features that can help you to enjoy your day with ease.
