Wi-Fi 6 is already a significant step forward compared to previous wireless internet standards, with better performance even in densely populated residential complexes or offices. There is already Wi-Fi 6E, which offers better bandwidth thanks to relying on a frequency of 6 GHz rather than 5 GHz or 2.4 GHz. And to make matters even more complicated, the Wi-Fi Alliance has announced another iteration of the standard during CES 2022, Wi-Fi 6 Release 2. This standard promises greater energy efficiency and even better performance when dealing with increased device and traffic density.
The highlight of Release 2 is certainly the support for multi-user MIMO for uplink, allowing connected devices to simultaneously upload content to an access point such as a router. This allows faster and more reliable shipping from multiple people at the same time, and will also improve latency in games and video conferencing.
For those who have dozens of smart home devices scattered all over the house, Wi-Fi 6 Release 2 brings improvements in power consumption. Devices using the new standard can rely on new low power and sleep modes, which is especially interesting for battery-powered products.

Wi-Fi 6 Release 2 features apply to all supported standard bands including 2.4 GHz, 5 GHz and 6 GHz. This is important because all three have their own use cases, with 2.4 GHz often still remaining the only option in low-power smart home devices, as it is the cheapest technology and the one with the longest range.
Improvements in battery consumption will mostly help smart home devices, but it is safe to assume that smartphones will also benefit slightly from the range of enhancements that come with Wi-Fi 6 Release 2.
Given that Wi-Fi 6 was supposed to be a new beginning for the complicated and complicated naming scheme to which Wi-Fi previously relied on, turning a non-intuitive Wi-Fi n / ac / ak scheme into a logically advanced Wi-Fi 4, 5, and 6, it’s a shame we’re stuck again with a system that makes us scratch what’s what, while Wi-Fi 6, Wi-Fi 6E and Wi-Fi 6 Release 2 coexist. It is especially discouraging that Wi-Fi 6 Release 2 is intended to improve both Wi-Fi 6 and 6E, which makes it even harder to understand.
