technique for 4G/5G – i.e. it is used to relieve the load on the 4G/5G
networks, with Wi-Fi antennas being used alongside the mobile
network antennas. Predictions are that offloading will come to
represent three quarters of the data rates of mobile terminal connections.
In addition, Wi-Fi represents high data rates across hotspots, but using
the Internet rather than the mobile access networks. The version of WiFi for the world of telecommunications can take a variety of forms. For
the moment, Wi-Fi Passpoint is the version which seems to be the most
popular. Passpoint is championed by the Wi-Fi Alliance, which has
already shown its strength, promoting the use of Wi-Fi through proving
the conformity of products. However, other solutions are also being
studied by the standardization organizations, such as replacing Wi-Fi
with LTE antennas and equipping all terminals and servers with LTE
ports, referred to as Home eNodeB (HeNB). We shall see that this
solution fits into the context of software networks, with the dawn of
software LTE.
We shall begin by examining the new generations of Wi-Fi, which
have the necessary capacity to deal with the exponentially-increasing
demand of users.
6.2. New-generation Wi-Fi
The new-generation of Wi-Fi began with the IEEE 802.11ac
standard, which was released in late 2013 and achieves data rates
higher than 1 Gbps. This minimum value of 1 Gbps marks the new
generation of Wi-Fi. The IEEE 802.11ac standard, which we shall go
on to examine in detail, is supplemented by IEEE 802.11ad, which
uses a new frequency band: 60 GHz. This solution is primarily
designed for the inside of buildings, and for very directional use
outside. Indeed, at these frequencies, the signal is very vulnerable to
interference from rain, dust and, of course, obstacles. Thus, to use it
outside, we need a direct path to the access point, with good weather
conditions if possible, or at least a short enough distance for the data
rate to remain correct, even in the presence of rain or fog.
The new generation continued with IEEE 802.11af, which uses
cognitive radio – i.e. the possibility of using frequencies for which
