Wireless Communication

I am about to work on a wireless project that will involve a full duplex wireless communication. Does any one in here know of any good RF transceiver modules that also does handshaking capabilities?

In order for the communication to be full duplex you will need two separate channels. Can you give us some additional information like data rate and distance? How much are you willing to spend? Where are you located? Will the transmissions be legal in your country of residence.

How do you expect us to help if you give us nothing to work with?
