Is there overlap between these ITAR restrictions and mmWave radar coming to consumer Wi-Fi routers via IEEE 802.11bf in Wi-Fi 7 (2024)? There are open-source projects which demonstrate Wi-Fi Sensing on $20 Wi-Fi devices, no SDR needed, plus a handful of commercial products with Wi-Fi "motion detection". There are also several hundred public academic papers on the subject. https://news.ycombinator.com/item?id=31561338#31563572 https://news.ycombinator.com/item?id=31561338#31563572
Edit1: is Wi-Fi (2.4Ghz+) radar excluded, due to limited range?
> (xxvii) Bi-static/multi-static radar that exploits greater than 125 kHz bandwidth and is lower than 2 GHz center frequency to passively detect or track using radio frequency (RF) transmissions (e.g., commercial radio, television stations); https://www.ecfr.gov/current/title-22/chapter-I/subchapter-M/part-121 https://www.ecfr.gov/current/title-22/chapter-I/subchapter-M...
Edit2: 2.4Ghz Wi-Fi can "see" reflections from moving objects through walls and other physical obstructions, at distances much greater than 0.2m from the obstruction.

- eskaytwo 4y agoThe range on those would be minimal and trivial for any air-based weapons concerns. Definitely home privacy implications but they’re probably less of a concern for ITAR.
