While I get the reason for backwards compatibility, reason also states that compatibility must stop somewhere. A large part because of advancements being held back by old 2.4Ghz stuff. Where home internet requirements are now in the 200-300Mbps minimums because of the WFH/HBL zooming and all, people are still having inadequate coverage and complaining internet is too slow despite their 1Gbps plans being more than sufficient to support 5 users doing concurrent Zoom calls with plenty of bandwidth for other applications like surfing and streaming too. You can still find 802.11n 1x1 20Mhz stuff today, and 2022 is almost upon us in 40 days or so. They need to be cut off properly and devices evolve to take advantage of improvements.įor health reasons, being blanketed by that amount of radio waves is certainly troubling.Ĭlick to expand.If you ask me, I prefer they make a clean break to dated technology. Even today in 2021, we still have 802.11g/n 20Mhz devices holding back speed improvements that have come with newer standards. There needs to be a line drawn if we want to make that leap in speeds. But it means our overall investments also go up significantly.Īnd backwards-compatibility must stop somehow. Then there's the question of applications - all the high speeds are wonderful, but if that means that our videos get richer and our overall bandwidth usage goes up sharply, then I'm for it. And since we're speaking about 320 MHz bands, that's a lot of bandwidth! There's also an issue of power consumption against range, so 6Ghz is still dependent on tech advancements to maximise that kind of efficiency for low-power devices like phones and smartwatches. It actually strengthens a use case for 6Ghz networks in urban dense environments like Singapore, but it also means AP-in-every-room setups, not a cheap way to move forward. I like the theory of MLO on Wifi7 where devices can run on multiple channels simultaneously, though I am worried about the performance penalties - if everyone is on every channel, then wireless congestion related issues will be tremendously painful. While certainly exciting, there's still a lot that's unknown. Also, since 802.11ax is still undergoing evolution, the changes will snowball and affect the new standards - possibly adding to delays there. If it goes the way of 802.11ac, then it'll be a long, long, long time more when we include delays. First off, note that the specification is only in draft and final is expected only in early 2024.
