WiFi 7 (802.11be) will support up to 40 Gbps links, real-time applications

I still don't own a WiFi 6 router, but MediaTek has already started to demonstrate 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, 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.

    It's a disappointment that 10 Gigabit adoption has been slow for consumers. But you get to use existing/cheaper Cat 5e cables with 2.5GBASE-T, making it a straightforward upgrade from 1 Gbps. Almost everything that had a 1 Gbps port should just be changed to 2.5 Gbps. I don't know about the patent issues.

    2.5 Gbps ports are starting to appear more frequently, particularly on mini PCs []. On many ARM SBCs there's not enough I/O bandwidth to do a 10 Gbps port anyway.

    5GBASE-T seems more useless for consumers, a literal half measure. You can do 10 Gbps on Cat 6 or Cat 6A. []
