Actually it is physically impossible to have any wireless comms at all without giving away a unique identity that can be tracked. Not unless you're going to replace your phone's radio every time you send some data. Every single transmitter has a unique fingerprint that can be identified relatively easily. It's called Specific Emitter Identification. If at any point a fingerprint is associated with your identity, it's trivial for a state actor to know exactly who and where you are every time your phone transmits something. They don't have to know what you're sending. The electromagnetic spectrum is not a private medium.

How things are aren’t the only way things could be.

A receiver could use a new random ID to call “collect” to a secure third party network which agrees to pay for the base stations bandwidth for every connection. The station then responds to the base station yep ID X’s bandwidth will be paid by vert tel.

Obviously, this doesn’t eliminate the possibility of tracking as you’d want the cell to have multiple connections created and abandoned randomly, but it does remove that ID you’re concerned with.

		GP is referring to manufacturing variance in the radio equipment, not the deliberately-inserted tracking identifiers. See, for example, doi:10.1016/j.dsp.2025.105201 and doi:10.3390/rs17152659 for relatively cheap approaches. The solution to this is just to make it illegal to store and process the results of such analysis applied to radio signals, without consent of the data subject (GDPR jurisdictions have that already), and to enforce that law.

You're confusing a technical limitation with a policy decision. Just because the cell tower (as currently designed) needs to know your fairly-precise location at all times, it doesn't mean that location needs to be stored indefinitely or used against you.

We could live in a world where we have strictly-enforced privacy laws. We don't, and that sucks, and if anything, we're moving further away from that state of affairs very day. But we could.
