This is more of a side-channel sort of thing. I'm honestly not too concerned. > However, an attackers ability to track a particular target is essentially a matter of luck. That being said, their proposed solution seems elegant enough: > a random time-varying extra frequency offset could be added to devices, which would alter the signal frequency periodically and make it difficult for an attacker to distinguish the device's unique signature
