Spoilers: it won't: noisy neighbours, congested bands, and actual real world mean getting more than what we are already getting is next to impossible. Because basically those same factors are holding back even top speeds of wifi5, nevermind 6/6E
Raising the maximum possible raises the average as well. Not at the same rates, but there will definitely be improvements in the less visible bits like error correction, accounting for echo, etc.
Call me sceptical then. We're pushing Shannon's law essentially already
You're sceptical! 😁
I've not heard of Shannon's law, but if you're referring to Shannon-Hartley theorem then, from my brief understanding, wifi 7 will still bring improvements in bandwidth purely from doubling the channel width. Doubling the number of antennas is probably not going to affect home users as those will probably be prohibitively expensive, but enterprise might snatch it up - who knows.
Increasing the antenna availability increases available airtime in a given band, reducing the airtme 'load' of IoT and similar devices on the spectrum. This alone would be a dramatic improvement, but increasing the modulation by a factor of 4 should dramatically reduce airtime utilization for normal client loads, regardless of available upstream bandwidth, resulting in more airtime for everyone else and dramatically improving wifi performance in congested environments, assuming access points are designed with sufficient memory to allow for buffering frames in this manner.
Wifi7 should be as big an improvement as 11b to 11g, assuming the hardware vendors don't shit the bed on it.
Thanks for expanding on this! Very helpful!
It’s not relevant anyway most people only have a gigabit as that’s more than enough for home users WiFi 6 and WiFi 6E are already great.
And how many devices even are on 80MHz nevermind the 160? Essentially the bands are too tight, with too few channels already, so wider channels aren't going to help that either
That is true but since I got all WiFi 6 compatible device beam forming in my case of apt makes up for it makes the signal and speed way better.
Internet connectivity isn't the only reason for faster networking speeds. A faster local wireless connection still has reasonable applications.
Not saying that I'll jump on board with upgrading all of my devices for the new annual wifi standard, but it's still cool that things are improving.
All my devices are already WiFi 6 compatible I really like beam forming my old router didn’t have this and I could tell the difference right away as I live in a apt speed and signal is way better.
