Initiating wideband simultaneous transmit and receive communications

A communication method comprising facilitating a communication network between a plurality of communication devices having a transmit signal path and a receive signal path, the transmit signal path and receive signal path being operable to simultaneously transmit and receive at the same frequency over an interference-suppressed band, by:

• generating a communication sub-band and an initiation sub-band within the interference-suppressed band, the initiation sub-band having a lower bandwidth than the communication sub-band;
• executing a polling stage in which a first communication device transmits a polling signal within the initiation sub-band to a second communication device;
• executing an interrogation stage in which the first communication device transmits an interrogation signal within the initiation sub-band to the second communication device;
• executing an authenticating stage in which the first communication device transmits a timing signal to the second communication device;
• and
• executing a communication stage based on the timing signal in which the first and second communication devices communicate by transmitting and receiving simultaneously at the same frequency within the communication sub-band.
