The Wi-Fi 8 standard now is in developmentand it’s funny because the Wi-Fi 7 standard is still starting to take off. Basically, it is something completely normal, these work cycles are common in the technology industry because they allow a greater pace of innovation to be maintained and speed up the achievement of very important advances.
MediaTek has been the first to comment on some of the most important advances that the Wi-Fi 8 standard will bring, and the truth is that we have been surprised to see that It will not mean any advance in terms of performance compared to the current Wi-Fi 7, since in both the maximum speed will be 23 Gbps (gigabits per second).
However, this does not mean that this standard will not bring important improvements on other fronts. Making a direct comparison between both standards we can see that Wi-Fi 8 will have a coordinated directed waiting time Instead of restricted, it will maintain OFDMA and multilink operations support, and will introduce the following new features:
- Multi-AP Coordination.
- Coordinated spatial reuse.
- Coordinated beamforming.
- Dynamic subchannel operation.
One of the most important differences between both standards will be the greater output efficiency of Wi-Fi 8. This will allow for much more stable download speeds, avoiding large oscillations that we can find with current standards. This is important because it will make this type of wireless connectivity more solid and much more reliable.
Coordinated spatial reuse will play a very important role in this regard, as it allows the creation of access points to harmonize power output. In this way, the connection of the closest devices can be optimized without affecting the connection of the most distant ones, improving output capacity by 25%.
As for coordinated beamforming, it is an extension of the classic techniques known in English as “beamforming” that we have already seen in previous standards. This new version can route signals between devices more preciselywhich significantly improves performance on busy networks.
With dynamic subchannel operation, data subchannels are assigned to devices based on their needs and capabilities. So, for example, if we are downloading the same file with several machines, this technology will automatically assign a subchannel to the most advanced ones so that the download is faster. This technology already exists in Wi-Fi 7, but has to be managed manually.
This new standard aspires, in summary, to improve the user experience on networks, and focuses on solving some of the problems that are common in busy networks, which tend to be the most problematic. Wi-Fi 8 is identified with the nomenclature 11bn, while Wi-Fi 7 is identified as 11be, and is expected to arrive between 2028 and 2029.
