For several months now we have been talking about all the advantages that Wi-Fi 6 brings and how in addition to improving connectivity and reducing latency, it works especially well in dense environments, where there are a large number of users, for example, in spaces open like stadiums, shopping malls and airports, or indoors like auditoriums or classrooms.
In its development that has lasted for more than a year, we have also witnessed the launch of the Wi-Fi 6E protocol, which offers better performance thanks to its use of the frequency of 6 GHz instead of the 5 GHz or 2.4 GHz.
But if this is not enough, the Wi-Fi Alliance has taken advantage of the last CES in Las Vegas, to present a new iteration of the new protocol, which it has baptized as Wi-Fi 6 Release 2. Among its novelties, its better energy efficiency stands out. and even improved performance when working precisely in environments with high device density.
One of the highlights of this second version is undoubtedly its compatibility with uplink multi-user MIMO, which allows connected devices to upload content simultaneously to an access point such as a router. This enables faster and more reliable charging of multiple people at the same time, and should also improve latency for both games and video conferencing.
In home or business environments where many connected devices are connected, Wi-Fi 6 Release 2 also stands out for better energy management, since devices that rely on the new standard will be able to resort to new low-power and sleep modes. This is especially interesting for battery-powered devices, such as many IoT or connected home-ready items. Even smartphones could benefit in this case, although it will also depend on the type of implementation made by different manufacturers.
All these features also apply to all the bands compatible with the standard (2.4 GHz, 5 GHz and 6 GHz). This is important as 2.4 GHz is often still the only option for low-power smart home devices, as it is the cheapest and longest-range technology.
The problem with all this? That the Wi-Fi Alliance has not taken too long to break its promise to provide a clearer outline when it comes to understanding the characteristics of its standard. And if it is true that it made progress by renaming it and going on to change the cumbersome previous names to Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6, that now in this latest review three slightly different standards are already coexisting does not exactly help to the cause.
