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.

    Why are wired routers still only up to 1Gb/sec.

    They should also have more than four LAN ports.

    Lowest common denominator.

    I would be happy to see 2.5 Gbps ports in all product categories.

      We're almost at the point where 10 Gigabit paptents are expired (1G was back in like 99, so it should have been up a few years ago, 10G was either '03 or '06 for copper) yet I imagine they patent encumbered 2.5 and 5 gig despite them using all technologies from 1G or 10G in their development.

        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 [notebookcheck.net]. 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.

    Because all people who don't understand technology know is two numbers: Price and price. If you want faster routers or more ports, then you can pay more money. But people would rather pay less money for what they think they need than splurge on things that seem optional.

      Better than 1Gbps is definitely optional. Only certain people in certain areas can get uplink that even has that much throughput.

        Within the house, there's more use, but even then, most people don't need that kind of speed enough to be willing to pay. Those that do, just buy enterprise gear. Apart from folks working with video files that they're copying to and from a NAS, I'm not even sure what folks would be doing at home that would use that kind of bandwidth.

    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?
