[EN VIDÉO] What are the impacts associated with the deployment of 5G? The arrival of 5G raises many fears and questions. What are the real impacts of its deployment on the environment, our health or the protection of our data?
While 5G is deployed in the region in the 3.5 GHz band, work on 6G has already started and experiments are increasing. Some are even ahead of this future generation which could multiply by 100 the flow rates compared to the 5G. This is particularly the case of China, which has already deployed its first experimental satellite dedicated to 6G.
For its part, Samsung has its own calendar and is betting on 2028 for the first steps of 6G. In the meantime, the South Korean is not idle. He just unveiled at the IEEE International Conference on Communications (ICC 2021) his latest works conducted with the University of California, Santa Barbara, United States. For scientists, the challenge of 6G is to exceed 100 gigahertz. This means that a mobile is already in the spectre du térahertz.
Terahertz as a playground
And this is what the researchers wanted to demonstrate by setting up a prototype with a 16-channel transmitter and receiver peaking at 140 GHz. During testing, the system achieved 6.2 Gbps over a distance of 15 meters. For the moment, this is the speed record, the previous holders being Nokia and Turk Telecom with a speed of 4.5 Gbit / s.
For researchers, the unit of throughput for 6G will likely be terabits per second, with latency reduced to a tenth of that of 5G. With such speeds, the high-tech giant conjures up an ultimate multimedia experience with augmented reality, holograms high-fidelity mobiles. Of course, the benefit of these advances will primarily benefit the manufacturer’s future 6G smartphones.
