- fryguy 16y agoThere may be a 160 byte block of space in the normal traffic your phone makes to the towers in order to let it know where you are. Maybe they should look into using that for something like this.
- wtallis 16y agoIt should be much easier for cell phones, since the underlying physical medium is a broadcast medium. It takes significant engineering effort to get rid of this capability.
- JoachimSchipper 16y agoThat would require a completely separate, unencrypted broadcast protocol. Yes, you could design that, but who will pay for it?
