can over rf
Hello,
I am developing a communication between two units that need to talk over two wires, distance is 100 to 500m maximum. The carrier has to be greater than 100kHz, reason is that this is the Nyquist frequency for other analog signals running on wires close to those for the comminication. Main aim is to avoid cross talk between communication and sigals, choosing two bands that do not overlap.
For this reason I avoided modems like v32bis, the carrier is too low. I am evaluating powerline modems, carrier is 130kHz, not very far actually, but might be a solution even if slow.
The question is: is it possible to use two RF transceivers connected by two wires instead of using the antennas? For example, I am thinking about using two CC1000.
Notice that it is not possible to use a coax instead of the two wires, that eventually can be twisted.
Any suggestion?
Thank you.
