"Xfinity using WiFi signals in your house to detect motion" (2025), 500 comments, https://news.ycombinator.com/item?id=44426726 "How Wi-Fi sensing became usable tech" (2024), https://www.technologyreview.com/2024/02/27/1088154/wifi-sen... There is one area that the IEEE is not working on, at least not directly: privacy and security.. IEEE fellow and member of the Wi-Fi sensing task group.. the goal is to focus on “at least get the sensing measurements done.” He says that the committee did discuss privacy and security: “Some individuals have raised concerns, including myself.” But they decided…

(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 ... individuals should be provided the opportunity to opt out of SENS services – in other words, to avoid being monitored and tracked by the Wi-Fi devices around them. This would require the…

"Seeing through walls" motion detection can be done with Doppler imaging and commodity Wi-Fi today using custom firmware. Hundreds of research papers have been published on this topic. The upcoming IEEE 802.11bf standard is scheduled to add that capability to every router in 2024, https://news.ycombinator.com/item?id=27123493 & https://www.theregister.com/2021/03/31/wifi_devices_monitori... > In three years or so, the Wi-Fi specification is scheduled to get an upgrade that will turn wireless devices into sensors capable of gathering data about the people and objects bathed in their signals...…

Future Wi-Fi devices will be able to see through your home and business walls, for activity monitoring and biometric identification, https://www.theregister.com/2021/03/31/wifi_devices_monitori... > In three years or so, the Wi-Fi specification is scheduled to get an upgrade that will turn wireless devices into sensors capable of gathering data about the people and objects bathed in their signals... When 802.11bf will be finalized and introduced as an IEEE standard in September 2024, Wi-Fi will cease to be a communication-only standard and will legitimately become a full-fledged sensing…
