We need more funding for open-source WiFi Sensing counter-measures, e.g. EU research, https://ans.unibs.it/projects/csi-murder/

> this paper addressed passive attacks, where the attacker controls only a receiver, but exploits the normal Wi-Fi traffic. In this case, the only useful traffic for the attacker comes from transmitters that are perfectly fixed and whose position is well known and stable, so that the NN can be trained in advance, thus the obfuscator needs to be installed only in APs or similar ‘infrastructure’ devices. Active attacks, where the attacker controls both the transmitter and the receiver are another very interesting research area, where, however, privacy protection cannot be based on randomization at the transmitter.

> The experimental results obtained in our laboratory show that the considered localization method (first proposed in an MSc thesis) works smoothly regardless of the environment, and that adding random information to the CSI mess up the localization, thus providing the community with a system that preserve location privacy and communication performance at the same time.
