Can you piggyback RF communications on cellular transmit/receive frequency bands ? Answered
My question is purely hypothetical and there is no immediate plans for any such application. But I was just curious is it possible to make use of the cellular frequency bands (as set out by a country's regulations and by the cellular providers) for some sort of covert type communication other than for voice, data or text types of cellular communications ? Would it be too difficult and complex to develop such an application that uses cellular radio frequencies or could it be done without too much concern for potential interference or the sharing of channels of nearby normal cellular transmissions ? Could such an application be developed without having to cross over many hurdles ? If this covert communications is possible would the cell frequencies used not reach the base stations of the wireless carriers as noise or can a peer to peer communications be possible by passing the base stations ?
