5G Networks

When you mention 5G networks, the first thing that comes to mind for many of us is the highest speed of the Internet is unprecedented, and it’s all about very fast downloads, and loading web pages faster, but speed is one of the many features offered by 5G networks.

5G is described by many as the technology that will change the world, where it will become as important as electricity, or cars, because of its huge impact on the global economy.

5G networks will provide faster, more reliable connections, and high-speed Internet connectivity, meaning more reliance on cloud services, and the creation of a new class of electronic devices that can exchange data and information quickly enough for immediate decisions.

5G networks can also be used to develop autonomous cars through instantaneous exchange of information and data between vehicles, to help reduce congestion, as well as to develop drones and high-speed trains, and will also help usher in a new era of electronics, where Smart devices, smart clothing, and everything connected to the Internet will contribute to the prosperity of the Internet of Things (IoT) by building a new economy based on the Internet of Things on a large scale.

Of course, none of these things will happen overnight, but it will take years and years for the availability of 5G networks on a global scale, where smart cities and big companies will get them first, while it will take years to reach all the world’s cities.

However, we know that 5G networks, when available, will change the world around us, and there are many areas, and industries will change radically, and it will be much more than just super speed.

Here are 5 results of using 5G networks that are more important than super-speed:

  1. Better voice calls

    There are many free instant messaging apps like WhatsApp, Telegram, Viber, etc. Apart from being free, there are other reasons why some users use the messaging app to make voice calls. Voice calls – WhatsApp, Any VoIP service based on VoIP, such as Skype, Zoom, or Google Voice – is much clearer than the telephone network.

    But high-resolution audio was not a top priority for 3G or 4G designers, but it was different when designing 5G networks, as audio accuracy became a top priority, so you can expect to make all your voice calls and video calls quickly And without interruption, and more clearly.

    Over time, the audio resolution is supposed to go beyond HD, reaching what is called Voice over 5G, which seems to be an integral part of other 5G services, such as video calling, Telepresence, And Augmented Reality, and Virtual Reality.

  2. More capacity

    5G networks are the first generation of mobile networks that are designed for M2M communication, so there is an important part of the 5G network specifications, known as mMTC, which means that a huge number of machines are connected at the same time. Type of connections we will find up to a million connected devices per square kilometer, which is what the IoT world needs.

    Why is this important? Let’s assume you are inside a sports stadium, amid a crowd of 50,000 people, now with 4G networks it’s hard to get a signal to make a call or send an SMS during the game.

    But the situation will be different with 5G networks. Anyone in a big event will be able to connect online, stream live video, make calls, and will also find more technologies that make it easier. Anyone on the pitch can broadcast live from their phone, and viewers can even wear VR glasses, which broadcast live videos from all the cameras around the stadium, giving them a closer view of the game.

    Away from the stadiums, 5G networks will be very useful in crowded places, where live updates are important, as in airports and train stations, giving us better connectivity on the go.

  3. The development of self-driving cars

    The core connections that will be supported by 5G networks include URLLC, which means faster connections, with high reliability, providing instant, reliable connections between the network and devices. This will make the widespread commercialization of autonomous cars a reality, as vehicles can be allowed instant updates on their speed and location.

    The C-V2X technology will also help vehicles communicate automatically with each other, as well as with other connected nearby devices. This will eventually lead to so-called Platooning, which means that a group of vehicles can travel together safely and at high speed, which Helps improve traffic management, fuel efficiency.

    How it works is that each vehicle communicates with other vehicles at high speed, and there is the main vehicle that controls speed and directions, and all of the following vehicles respond to it, which will accurately match the movement of the brakes and acceleration with the movement of the driving vehicle.

    Although the biggest impact would be in favor of traffic, but the main use of technology is not more efficient for the transportation of personnel and goods only, but also to reduce carbon emissions, and environmental pollution.

    Gunnar Tornmalm, head of systems development at Swedish company Scania, says: “In addition to the Platooning process, it helps improve highway traffic and reduces the environmental impact of transportation, saving 25% of fuel consumption also”.

    “This technology will not reach the market on a large scale unless vehicles from more than one brand can communicate with each other, and that is not far off.”

  4. Development of Mobile Broadcasting Services:

    You can now stream 360-degree videos on Facebook, but their quality is poor, which is what breaking news coverage is experiencing, which is currently broadcast at low resolution, but newsgathering and live sports coverage now need to rely on 4K. Move to: 8K, Augmented Reality, and Virtual Reality.

    LiveU has recently begun working with AT&T to bring 5G networks to its mobile broadcasters and will test the effects and performance improvements that 5G networks can produce in live video.

  5. High risks to human health

    Although 5G will make a lot of positive changes, it will have some negative effects. Perhaps the biggest concern to date is the health problems it may cause to humans – the spread of cancerous diseases specifically – as a result of the installation of many (Antennas) antennas in cities to create 5G networks.

    In November 2018; presented more than 180 physicians and scientists, a broad European Union calls for a halt 5G networks run urgently, because of the potential of this new technology serious health effects.
    The major concern is that the exposure to electromagnetic fields of RF-EMF is greater than that of 2G, 3G, 4G, Wi-Fi, etc. of already existing communications, where RF-EMF has proved to be harmful to humans and the environment.

    Dr. Harrell L. professor of oncology at Sweden’s Örebro University, said: “Telecommunication companies are trying to introduce this new technology that may have real and unintended adverse consequences, which will affect the health of humans, plants, and animals.”

    The New York Times also published a report showing what a study revealed about the existence of “some evidence” on the dangers of mobile phones, and their association with cancer, at least in mice, so this discussion is expected to continue.
