I wonder if it’s actually possible to prevent fingerprinting of a radio transmitter (aside from active measures like intentionally sending out noise broadcasts periodically): it seems to me that a clever enough adversary with two or three receivers could fingerprint all the devices in the area based on transmission patterns and locate/identify individuals. Combined with CCTV or other data, this could even be sufficient to pinpoint irl identities.
