Cell phones are continuously handshaking with cells now, I believe - and
there's been legislation enacted to localize a cell phone within a cell,
for 911 / safety concerns. It would not take much to add smart advertising.
At least, I have seen my old "Primeco" (2 GHz PCS?) phone transmitting on
its own, while I was using a spectrum analyzer. Perhaps this is not true of
all phones. The transmissions were on the order of milliseconds, and could
easily be pre-empted by incoming calls in a properly designed system.
