First and foremost, Wi-Fi Certified 6 Release 2 offers greater uplink capacity. It adds support for uplink multi-user MIMO, allowing multiple devices to upload content concurrently to an access point (AP). It supports transfer speeds of up to 9.6Gbps, which is more than double the maximum speed supported by Wi-Fi 5.
New features introduced in Wi-Fi 6 Release 2 will work across all three bands — 2.4GHz, 5GHz, and 6GHz — supported by the Wi-Fi 6 standard. The new release comes as the adoption of Wi-Fi 6 continues to grow by leaps and bounds. According to the Wi-Fi Alliance, nearly 2 billion Wi-Fi 6 devices are set to enter the market in 2022.
So it will be great for on-premise gaming, backups to NAS devices, mesh networking etc, but no residential WAN connections come anywhere near this performance. Even though I have a Wi-Fi 5 device at home, I still find the good old 2.4 GHz is more reliable and has better range, even if it is a bit slower.
