I'm looking into using a simple RF Transmitter/Reciever to work within a daily driven vehicle. (the RF-KLP on sparkfun.com)

Since I plan on selling my product.
My concern is how to ensure that the RF signals from one vehicle do not affect another vehicle. (since all the componets will be the same, using the same frequency transmitter/recievers.)

obviously you include an ID string in each transmitter and reciever controller. if a reciever recieves an ID string that does not match its own, it ignores it.
That would be a minimum requirement. But this does not allow for collision detection etc.
Ideally each transmitter would have a reciever aswell, so it can wait till other transmitters are finished sending information, and it could then send its own. like CSMA/CD
