Patent ID: 8547960

Claim:
A method of communication, the method comprising: transmitting a communication signal having a synchronization preamble from a first node; setting a local clock of at least one second node pursuant to the synchronization preamble to synchronize communications between the first and at least one second node; and exchanging subsequent communication signals between the first and at least one second node without additional preambles until synchronization suitable for data communication is lost; wherein exchanging subsequent communication signals between the first and at least one second node without additional preambles includes: transmitting one or more subsequent communication signals from the first node to the at least one second node without additional preambles; and when a link reversal point is encountered: performing a sub-frame duplex to receive at the first node one or more subsequent communication signals transmitted without additional preambles from the at least one second node; and adjusting a local clock at the first node to take into consideration propagation time between the first node and the at least one second node.
