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.

    I upgraded my home lan to 10gb fiber this past summer. People on ebay are selling QLE8140 cards dirt cheap. They do 10gb ethernet and also do FCoE which is maybe why nobody buys them. But anyhow they don't even need lots of airflow like other 10gb cards. Drivers are available for Linux and Windows 10. Now onto the switch. The cheapest 10gb switch you can get is the MikroTik CRS305-1G-4S+IN. I went a different route and bought a used Aruba 48 port switch with four 10gb SFP ports. They're meant for stacking but you can abuse them for this purpose. They don't care what transceiver you use either. So couple all that with some fiber from monoprice and everything is running great. The switch ports max out at 6gb according to Iperf. Can't complain for the $60 price. Cards were $15 each and the fiber was maybe $40?
