Approximately every 10 years, a new generation of wireless technology emerges.
The 5G is the next generation, the next revolution in mobile network telecommunications standards and the use of frequencies above 6GHz.
The goal is to connect the future 50 billion devices of the world.
The main objective of 5G Network will be to provide the platform to connect a large number of objects to the Internet, and thus support the Internet of Things (IoT). The 5G could cover the needs of Virtual Reality (VR), Augmented Reality (AR), Internet of Vehicles (IoV) or auto driving cars, smart buildings / homes, smart phones, computers, portable devices and industrial automation.
Compared to 4G, 5G will allow a 10X improvement in performance , a 10X decrease in latency , a 100X improvement in traffic capacity and a 100X improvement in network efficiency . 4G will continue to improve over time as well.
With respect to the network architecture, 5G Network will use the MIMO concept of Massive, MIMO multiuser. Massive MIMO is already used for 4G LTE and LTE Advanced. The massive MIMO base stations are equipped with many antennas located or distributed around the main site of the base station, to mitigate the effects of noise, fading and multiuser interference.
In the Massive MIMO concept , a large number of antennas (usually 32 to 64) are used in the Base Station simultaneously to serve tens or hundreds of users or mobile subscribers (MS) in the same time frequency network. 5G Massive MIMO can support up to 256 antennas. A massive MIMO with 128 antennas could provide 12 times more spectrum efficiencies compared to the existing 4G network.
AT & T and Verizon pre-5G arrived last year, but the first official releases of 5G will be made this year in the United States, with a broad deployment in 2019.
The first 5G offers will arrive around 2019-2020.
