And here we go again for a new race. This time again, as in 2012, it is about experimenting with a new mobile network standard, the 5G, announced for 2020 and presented as ten times faster than 4G. And this time again it is for operators to be the first to build a network and market a compatible mobile offer.
In March 2012, Bouygues recalls that he was the first to plant his flag on the planet 4G. First place contested by Orange and SFR
In any case, Bouygues Telecom plans to be the first on the starting line in 2020. Tuesday, July 3, in Bordeaux (Gironde), its CEO, Olivier Roussat, announced the launch of an "experimentation in real conditions", on the Gironde metropolis. "We are the first in Europe to launch tests between two sites," he enthused.

Starting from a mobile mini-network consisting of two remote antennas of 10 km, co-built with the equipment manufacturer Huawei, the operator tested before a meeting of local elected officials and journalists several promising mobile applications.
Here is what we
The novelty: almost more latency
Latency is the duration that a signal goes through a mobile network. In 4G, it still translates into a slight shift that poses a problem with sensitive applications such as surgical telemedicine.
This Tuesday at the Museum of Contemporary Art in Bordeaux, Bouygues had prepared a comparative test 4G / 5G race networked virtual car: two seats with steering wheel, two players equipped with virtual reality glbades, each connected to a different network.
Ten times faster
In theory, the flow of the 5G (up 10 Gigabits / second) will be ten times faster than 4G capable of achieving – in theory – 1Gbit / s. Where today it takes 10 minutes to load a video, this time should fall to 2 minutes, according to Bouygues experts, who point out that some delays are incompressible.
To demonstrate this rise, the Operator circulated in Mérignac (Gironde), in the suburbs of Bordeaux, a van packed with 4K cameras (Ultra High Speed) whose images were sent simultaneously on ten TV screens installed in the museum, in the city center of the Gironde capital.
If we do not see, for the hour at least, the interest of the experiment, it was successful: a circular wall of very high quality images allowed to believe live at the controls of the van. Enough to satisfy the speed required for the future standard of ultra-high definition 8K televisions

also attend a telemedicine consultation with exchange of several patient files and data, and an badisted technical intervention exercise. A remote expert could advise and see what the technician saw on site thanks to holographic glbades. Data searches and exchanges were seamless, with perfectly fluid images.
During the various demonstrations, the mobile network was able to reach the maximum bit rate of 2.3 Gbit / s. It is still far from the promises, but much more important than what 4G is currently offering us, around 22 Megabit / s.
"In the beginning, we will no doubt satisfy the industrial demand that will not be 'emerge, says Jean-Paul Arzel, vice president of Bouygues Telecom. 5G will also do a lot for the digitization of companies.
Targeting each mobile
Unlike 3G and 4G, 5G antennas do not "water" a sector, they target each user through special cells that can even follow him in his travels . The radiation effects of the antennas are thus diminished, badured us a network manager and a network architect interviewed on the spot.
Antennas, smaller than 4G, will be added on existing sites 2G, 3G and 4G continuing to serve. Between targeting and the highest speed, 5G will also absorb Internet consumption growth.
Since Tuesday, Orange and SFR announced that they will launch their tests on Marseille (Bouches-du-Rhône) for the first, Nantes (Loire-Atlantique) and Toulouse (Haute-Garonne) for the second. The race is just beginning!
