Take a look at Figure 10, mind blowing. This tech will make it into every device with an RF receiver. Your TV, phone, router, computer, tablet, fridge, lightbulb will know your pulse and waste size at all locations in your house.
What kind of measures for privacy can be implemented for this? Technically or regulation wise.
Another defense, impractical for most people, is for their house/office to be physically protected by a tall fence that is far enough away from the building to exceed radio range, along with sensors at the fence to detect someone attempting to broadcast into the property. This could be combined with shielding to reduce the necessary fence-building gap.
Regulatory responses: some countries could restrict this technology to high-frequency 60Ghz mmWave which doesn't easily pass through walls. That would at least reduce the social issue of X-ray vision (via 2.4Ghz WiFi) through the exterior walls of existing homes and businesses.
One of the 802.11bf papers proposed an opt-out mechanism where human biometrics could be registered into a giant database and you could ask WiFi devices to unsee some humans. Good luck with that.
Another regulatory response could be to delay approval of Wi-Fi 7 and shipment of Wi-Fi Sensing devices until the WiFi industry pays to upgrade all existing houses with RF shielding, i.e. never. Maybe it would be sufficient to wait until the homes of celebrities and politicians were RF shielded? Let's not forget IP-sensitive and financial business offices with people typing on keyboards. And using combination locks. And...
From the abstract: "This paves the way for low-cost, broadly accessible, and privacy-preserving algorithms for human sensing." How much do we have to wait for the follow up paper: "Human identification through wifi signals" and then the patent for "Wifi as an identity tracking source for advertisement in public spaces" Technology advances make me sad those days...

Sign me up for the security system. This seems like a total game changer if it's possible to do real human detection and tracking in a secure location.
> The U.K. Ministry of Defence has funded a study to determine whether it could be used to scan buildings during urban warfare. With improvements, Woodbridge says, the device could become sensitive enough to pick up on subtle motions the ribcage makes during breathing, which would allow the radar to detect people who are standing or sitting still.

If it can detect breathing of humans reliably, then it solves a huge problem in having home automation with automatic lighting - particularly in bathrooms. I've never had a decent bathroom occupancy sensor (they all end up wanting to detect fairly large motions) - the obvious solution is AI with a camera but for obvious reasons no, but if a couple of base stations can localize person positions to rooms in the house (and provide other services) then that kind of solves the whole issue!

Technical defenses are either cat & mouse CSI electronic warfare or shielding the walls+floor+roof+windows of some rooms (e.g. research labs in business, industrial systems, WFH offices, bedrooms) with materials like aluminum radiant barrier, RF window film or expensive drywall (e.g. QuietRock) designed for RF shielding of SCIFs.
