Wi-Fi Sensing (802.11bf) was scheduled for WiFi 7, which is present in recently announced "AI PCs". It works best with an on-device "AI" NPU that can perform inference on WiFi radar signals reflected from local humans and objects, to infer surrounding movement, breathing, keystrokes, location & more. It wasn't mentioned in recent device announcements, so perhaps the device firmware and algorithms are awaiting regulatory approval?

> the first commercial Wi-Fi sensing feature of Wake-on-approach and Walk-away lock on Intel’s Raptor Lake platform. This feature detects when a person approaches the PC so as to bring it out of sleep and get it ready for user input by the time the person reaches the device ... Intel Labs will demonstrate an early prototype of breathing detection .. The solution detects the rhythmic change in CSI due to chest movement during breathing. It then uses that information to detect the presence of a person near a device, even if the person is sitting silently without moving. The respiration rates gathered by this technology could play an important role in stress detection and other wellness applications.

I feel you. I was very disappointed with the noise made by my nuc7i5bnh. Did a bit of research and found out that a) the default BIOS fan settings are crap and b) the installed fan is crap as well.

Found some recommendations for the fan [1] and BIOS fan settings [2] on the internet and got my NUC completely silent. Perhaps that works for you as well?

Did a bit of research and found the following one getting recommended: https://www.amazon.de/gp/product/B07C8H5WHP

Installed it and it was SO MUCH quieter.

Sorry, but that understanding is dangerously incomplete. You're describing the first set of faults they uncovered, but there's also:

"Microcode and BIOS code requesting elevated core voltages which can cause Vmin shift especially during periods of idle and/or light activity" (emphasis mine)

https://community.intel.com/t5/Blogs/Tech-Innovation/Client/Intel-Core-13th-and-14th-Gen-Desktop-Instability-Root-Cause/post/1633239#:~:text=Microcode%20and%20BIOS%20code%20requesting%20elevated%20core%20voltages%20which%20can%20cause%20Vmin%20shift%20especially%20during%20periods%20of%20idle%20and/or%20light%20activity.%C2%A0

Recall also that "Vmin shift" means "the minimum voltage the processor needs to run correctly goes up" so if the issue isn't addressed, that level of undervolt may stop working

Why would you buy an expensive card that doesn't allow AP mode on anything ac or ax?

"Hello IAmMrZ

Thank you for your patience in this matter.

After checking this further, we would like to inform you that the engineering team confirmed that Intel® wireless products follow regulatory compliance and it is expected that AP mode cannot be enabled in non-2.4 GHz channels. We hope this clarifies your concerns.

Best regards,

Andrew G.

I'll be trying realtek 8822ce and 8852ae based pcie cards, using mainline Linux rtw88/89 drivers.

Qualcomm based cards are also quite common in high end wifi routers. But they are pricey.

This it not what I am referring to. I am referring to the chart posted in their official community post, most recently in June [1]. The chart is labelled "Intel Recommendations: 'Intel Default Settings'" (sic). Notice how "Baseline" is incomplete, and so is "Extreme". Also notice a bunch of notes saying "Intel does not recommend baseline" included on their "recommendations" chart. There's more of little gotchas like that if you pay attention. Also note that this chart has been quietly revised at least once as I have a version from back in April that was less stringent and less guarded with notes than it is now.

It seems obvious that with hardware-level memory safety on the way[1], just gradually modernizing existing C and C++ codebases to take advantage of safer constructs (like smart pointers or checked arithmetic) makes much more sense than rewriting everything in Rust. Even better, thanks to GCC, is that you don't need to sacrifice any portability to take advantage of even bleeding-edge features, due to its front-end/back-end separation and multitude of supported platform back-ends. Fish shell had to drop support for some platforms when it was rewritten in Rust[2].
