I spoke with a startup that is using 5G cell towers as radar. They said it is high-enough resolution to perform gait recognition.

That sounds suspicious. Gait recognition is extremely difficult to do with any accuracy even with high resolution video in semi-controlled environments. Doing with with opportunistic 5G signals sounds far fetched.
