The Wi-Fi Alliance organization has unveiled the specifications for the new Wi-Fi 6 Release 2 standard, which has improved some data and power consumption features.
Wi-Fi 6 Release 2 supports the 2.4 GHz, 5 GHz and 6 GHz bands and MU-MIMO – multi-user multiple input / multiple output on the uplink (data upload). Previously, priority was given to data uploads.
The new standard also optimizes power consumption and supports TWT (Target Wake Time) technology, which allows connected devices to determine the activation frequency for sending or receiving data. This helps save power.
Another way to save power consumption is to support the Spatial Multiplexing Power Save (SMPS) dynamic multiuser power saving method. It allows devices to turn off the reception of redundant data.
More than 2 billion Wi-Fi 6 devices are expected to be available in 2022. The largest hardware manufacturers, including Broadcom, Infineon, Intel, MediaTek and Qualcomm, have already announced support for Wi-Fi 6 Release 2.
