"The old 4G was an evolution of its predecessor 3G, with more bandwidth and more speed, but overall you could say that is the same ecosystem, while the new 5G aims to enable a range of applications that are out of this ecosystem, "as we might call eHealth. 4.0 industry or transport for example, said Viktor Arvidsson, who is the strategic director in France of the company Ericsson.
For users, the 5G should provide more speed and more bandwidth to allow the development of online video, virtual reality or even the arrival of holograms in the not too distant future, we are confident.
But far beyond human needs, the largest and main challenge 5G is the expected explosion of the "internet of things" in fields such but as varied as can transportation or industrial machines for the 4G was not adapted .
Everything is a matter of milliseconds
We could say that thanks to the use of a spectrum of wider wave, increasingly numerous and adapted to different radio waves and also due to greater convergence between fixed networks and antennas mobile will be possible to accelerate the speed of transmission data, an absolute and imperative in the famous internet of things.
"A network with a latency of a few milliseconds for the car for example be necessary. With 4G, an autonomous vehicle at 100 km / h need three meters of the brake while the 5G only be a few centimeters, "said Mérouane Debbah, mathematical and algorithmic director of the multinational Huawei Paris headquarters.
Pilot testing
The second stage of testing 5G is currently done through public-private consortium Partenariat 5G (5GPPP), which is controlled by the European Commission, with the will to develop by 2018 the technical solutions to address the problems linked future uses and benefits.
It quickly came to a normalization of 5G, the European Union would inject up to € 700 million in the 5GPPP, would receive 3,000 million from the private sector.
