The first time I heard about this was in 2013 and, in 2019, I had a local government management class where wifi sensing in busy downtown areas and stadiums was discussed as a plus side to municipal wifi installations. In the latter case it was described as being available not too far in the future.

Sensing is officially going to be part of 6G, might not be deployed everywhere, but it’s going to be in the standard.

Sounds like the higher frequency 6G would have better resolution (potentially sub mm?) than Wifi 7’s ~5cm. Article about 6G ISAC.
