Transmitting low-latency or uncompressed video over wi-fi is a big bottleneck at the moment: probably what they had in mind with mentioning VR headsets, but it has much wider-ranging applications than that. For example, putting wi-fi dongles into various screens around your house and being able to send video from any device to any screen.
I actually do wonder if we will be the point where, when PS6/Xbox Next launch in say 2028, they will offer some type of WiFi Direct connections to newer TVs at the time. HDMI will still be there too of course, but for those on the newest tech, it would be one less cable to have and make wall mounting TVs even more appealing.
Doubt it, even if they did it would suck like the steam streaming due to latency. Radio waves can be made to carry more data, but we can never make them faster. So latency will never be overcome without a faster medium such as laser/optical based data transfer or traditional electric signals over wire.
Radio waves propagate in air at nearly the speed of light, they are not the issue. The issue is the additional latency when transmitng and receiveing data, the electronics need to do "extra work" which adds latency.
It's actually 'slow cars blocking the lanes on the highway', to make an analogy of it.
By letting latency sensitive packets through both high speed and under 1 millisecond latency can be obtained. WiFi needs to meet those standards so when it's connected to a cable or fiber it doesn't become the bottleneck (of latency or bandwidth).

Both speed and low latency are possible using modern technology, it's the bottlenecks that need widening. Thank you early adopters for paying the way forward; so the rest can afford it in several years.
Logged in after maybe 5 years to say this - electromagnetic waves travel at one speed. 3x 10^ 8 m/s is what I remember, in a vacuum. Now the part I do not remember is how they travel in regular air. I think that's why light refracts. I would assume the difference is so infinitesimally small that it wouldn't even amount to 1 ns, let alone 1 ms, over domestic distances.
Since it's all energy wave propagation, maybe it is after all, the same speed. What do I know - I last studied physics 15 years ago.
I like to remotely control one computer from another on the local network. Lower latency is always a good thing. I don't care about higher speeds, although in theory applications like wireless VR could benefit from that.
It's an endless loop: 1) "Not enough channels available in this apartment building!" 2) New spectrum made available 3) Channels become wider until there's only room for 2 or 3 without overlapping 4) goto 1
Stop making babies and the population will decline. That should solve the problem by reducing the number of people operating WiFi devices. It will also dramatically reduce the total amount of impact stupid humans have on the planet to solve a number of other pressing issues.
Ignorance/stupidity could easily be addressed through better education. But currently the focus is on increasing profits and paychecks in colleges, universities, and schools instead of improving education.
But the root of a lot of the problems we face isn't stupidity but instead humans purposefully choosing bad methodologies. Which is why morality, which isn't talked much about in schools anymore, is important.
Surpassed wired? So... Wireless can give 800Gbps per link?
I think you mean *consumer* wired ethernet. Although I admit that the 400Gbps routers are extremely finicky and still being, um, "debugged in the field."

"In Wi-Fi 6, each user could get only ne RU."Should be "only one RU." Good article, thanks.

I have to say that this article certainly reads like what you typed, shadowjk.nandnandnand - Wednesday, January 24, 2024 - link
That's the perfect motivation to become a homeowner. Less congested Wi-Fi.PeachNCream - Thursday, January 25, 2024 - link

MLO with different APs simultaneously would be a gamechanger for finally achieving seamless handover, but of course that feature isn't there.
