Wi-Fi 6 Release 2 new standard released: faster upload, lower latency, more energy-efficient

Wi-Fi 6 has made significant progress compared to the old standard. Even in densely populated apartment buildings or offices, Wi-Fi 6 can still bring better performance experience. As for Wi-Fi 6E, it has expanded from 2.4/5GHz to 6GHz band, greatly improving the throughput of the network. What is confusing is that during CES 2022, the Wi-Fi Alliance actually announced the "second version" (Release 2) of the Wi-Fi 6 wireless network standard.

It is reported that Wi-Fi 6 Release 2 aims to bring users the "best home Internet experience" through faster uplink, lower latency, and better energy-saving measures.

Wi-Fi 6 Release 2 promises even better performance when dealing with more devices and higher traffic density — for example, support for multi-user MIMO uplinks.

This feature allows connected devices to upload content concurrently to a wireless access point such as a router, thereby improving the speed and reliability experience when multiple people use it at the same time, and reducing latency in games and video conferencing.

In addition, for users who have dozens of smart home devices scattered throughout their homes, Wi-Fi 6 Release 2 also brings improvements in power consumption.

The new standard allows compatible devices to enable improved low-power/sleep modes, which is a significant change for battery-powered devices such as smartphones.

Finally, the new features of Wi-Fi 6 Release 2 are applicable across all frequency bands (including 2.4/5/6 GHz).

Currently, the 2.4GHz frequency band is still the first choice for low-power smart home devices because it is not only low-cost, but also has a more significant advantage in penetration (transmission distance/signal coverage).
