Data transfer between two android phones

Question

I want to transmit data (few bytes) between 2 Andriod phones over as long a distance as possible. I don't want to use WiFi. Communication has to be directly between the 2 devices. Would it be possible to send and receive data over FM if I attach an FM transmitter? Is there a better way?

Not. I think its not possible. Android receives only allowed frequency approx. 88MHZ to 108MHz which is not allowed legally for hobbyists. If you'll communicate beyond this frequency that will not be received by android and if you'll communicate within legal band, it will be overlapped and not legal. You should prefer online data communication rather.
