(2021) privacy comments on Wi-Fi 7 standards work for 802.11bf, https://arxiv.org/pdf/2103.14918.pdf > it has been shown that SENS-based classifiers can infer privacy-critical information such as keyboard typing, gesture recognition and activity tracking ... since Wi-Fi signals can penetrate hard objects and can be used without the presence of light, end-users may not even realize they are being tracked ... individua…

No, the future is decentralized. In the US, you will always be tracked because of regulatory capture of the FCC. In Europe, your phone will display a tracking consent pop-up everytime you go into a cafe. If you don't comply, you will have to get your coffee and free wifi elsewhere.

I wouldn't be as negative. Frequently we create the tool in order to kill with it. After that we also use to tool to create. We're equally capable of good and evil and yes, we are frequently good, too.

It's not negative , it's true .

Technology can't be stopped by individual engineers refusing to invent it, it can only be stopped by everyone agreeing on the ways it shouldn't be used. So it was for arson (fire), homicide (every weapon since the rock), and obscene material (all communications technology), and so must it be for privacy and the various techniques of monitoring us.

Since 802.11bf makes most existing walls transparent, it should lead to innovation in wall construction. It may also increase market demand for light-based wireless networking (Li-Fi) which has the advantage of being stopped by existing walls.

https://www.rtinsights.com/li-fi-a-new-wireless-alternative-... > Li-Fi connections are broadcast over the air through a light-emitting diodes (LED) broadcaster and support rates up to 100Gbit/s ... Li-Fi can also serve to identify an object’s indoor position more accurately than Wi-Fi or GPS used today (less than 2cm and less than 3 degrees of orientation while it is providing real-time localization (less than 34ms)…

There's potential for visible-light networking but the Li-Fi people in particular are complete garbage. They claim visible light travels faster than radio waves and say Li-Fi is a hundred times faster than wi-fi but their thousand dollar router can only do 100Mb/s. They also rip off the Wi-Fi Alliance logo.

I'm surprised that there's not a single comment here about 802.11ay which is also 60GHz. Each channel on that standard can do something like 40Gbps, which is nuts. From Wikipedia[0]: > The link-rate per stream is 44 Gbit/s, with four streams this goes up to 176 Gbit/s. Yes, it can't penetrate walls, but is huge for point to point communication. Think VR headset bandwidth, file transfers between devices, wireless back…
