The Wi-Fi Alliance just announced the Wi-Fi 6 Release 2 standard. It brings improvements to uplink, as well as power management at all supported bands – 2.4GHz, 5GHz, and 6GHz – and is intended for routers and devices both at home and in the workplace as well as smart home IoT devices.
Release 2 adds support for multi-user MIMO uplink – the ability for multiple connected devices to upload to an access point simultaneously.
Wi-Fi 6 Release 2 is smarter with power management too. It supports new low-power and sleep modes that will particularly benefit battery-powered smart home gadgets.
Smartphones with Wi-Fi 6 support will gain some benefits too, once Release 2 features make it to Wi-Fi 6 and 6E devices.
