The 5G will not be a commercial reality before 2020 but already the operators and the equipment manufacturers show of what they are capable. At least theoretically. And it’s already the war of numbers. Recall that the 5G is obviously characterized by even higher rates higher than 10 gigabit per second but especially by more capacity and a very low latency, which is a major asset for the millions of connected objects that are currently deploying. The 5G has a good vocation to support the rise of the Internet of Things.
Last January, Orange and its partner Ericsson announced that they had achieved wireless communication with data rates greater than 10 Gbit / s. Orange emphasizes that this laboratory test relies on the bricks of the future 5G technology of the operator and the equipment manufacturer, in particular the centimeter waves (which have frequencies approximately 10 times higher than the waves currently used), new generations of antennas using the “massive MIMO”, an advanced radio focusing technique specific to 5G (“beam tracking”) that converts the power of radio waves to the position of the mobile, improving the efficiency of the system 5G.
Today, Bouygues Telecom shows the muscles indicating to have managed to reach 25 Gbit / s download, also in the laboratory (and also with Ericsson). The experiment was carried out using an Ericsson radio station equipped with active 5G antennas on which two prototype mobile terminals were simultaneously connected, and the Bouygues Telecom and Ericsson teams managed to carry out data transfers. simultaneously to two terminals, to achieve an aggregate rate of 25.2 Gbps on the 5G antenna with a latency of about 3 milliseconds.In parallel, two 4K videos were broadcast to the terminals “, explains the operator.
It is therefore a question of the addition of downstream flows via two terminals. Too bad also no mention of the amount of flow has been mentioned because the 5G also has its card to play in the problem of sending heavy files.
He continued: “This demonstration highlighted 5G’s ability to implement adaptive” beamforming “or” beamforming. “This technology, used with the massive MIMO in centimeter waves, will allow to increase the capacity of the mobile networks and the range of the signals to the 5G terminals In 4G, all the smartphones served by the same antenna must share the flow of this cell The beamforming allows, in 5G, to concentrate a beam Each terminal has its own “mini-cell” which follows it in its movements, and within which it has an optimum flow “.
“In the evolution of current 4G networks, the 5G will make it possible to offer, in particular, very mobile broadband, hyper-connectivity with the massive connection of communicating objects, ultra-critical connections of machines and vehicles thanks to the very high latency. The 5G is also an excellent opportunity to transmit ultra-high definition videos as well as Virtual and Augmented Reality to the terminal or home, as we demonstrate in partnership with Bouygues Telecom “, says Franck Bouétard, President and CEO General of Ericsson France.
According to the Ericsson mobility report, there will be half a billion subscriptions to 5G by 2022 globally.
For telecom equipment manufacturers, still fragile, this 5G will it constitute a windfall? Not really, feared the Gartner. “Yes, it will create activity but it will not be at the same level as for 3G and 4G because the deployments will be very different, and I think that some developing countries will not even see the color. It will not be such a promising activity but once again, it is essential for these actors to position themselves today and to show that they are ready, “explained Sylvain Fabre, an analyst for Gartner.
Operators will also have to specify their ambitions. “It’s up to them to find the right added value, the right position in the value chain, because when it comes to connected objects and dedicated networks, operators are not alone and more agile actors like Sigfox. , can change the deal “.
“On the other hand, the operators have quasi-exclusive assets such as the promise of quality, scalability, the possibility of tailoring for the industry, billing and of course security and robustness”, says Sylvain Fabre. In short, at a time when operators are trying to value their pipes at all costs (especially with content), the 5G associated with the Internet of Things could well be a stepping stone.
