WiFi 7 (802.11be) will support up to 40 Gbps links, real-time applications [cnx-software.com]
I still don't own a WiFi 6 router, but MediaTek has already started to demonstrate [mediatek.com] WiFi 7 (802.11be) to customers with solutions based on upcoming Filogic 802.11be processors which deliver "super-fast speeds and low latency transmission" and provide a "true wireline/Ethernet replacement for super high-bandwidth applications".
The company goes on to explain that Wi-Fi 7 relies on the same 2.4GHz, 5GHz, and 6GHz frequencies as WiFi 6/6E [cnx-software.com], but can still provide 2.4x faster speeds than Wi-Fi 6, even with the same number of antennas, since WiFi 7 can utilize 320Mhz channels and support 4K QAM (quadrature amplitude modulation) technology.
There's limited information about MediaTek Filogic 802.11be WiFi 7 processors since it will take a few more years before becoming available, but we can find more details in a document entitled "Current Status and Directions of IEEE 802.11be, the Future Wi-Fi 7" from IEEE Xplore [ieee.org].
