A communication system is provided. In one embodiment, a communication system includes communicant nodes. Each node includes a local clock, a transmitter/receiver circuit and a control circuit. The local clock is adapted to clock operations of the communication node. The transmitter/receiver circuit is adapted to selectively transmit and receive communication signals. The synchronization circuit is adapted to synchronize the local clock with a received communication signal from another communication node to establish communications between the communication nodes. The control circuit is adapted to control the transmitter/receiver circuit and the synchronization circuit. The control circuit is also adapted to process communication signals and to direct communications between the communication nodes without re-synchronizing the local clock until the clock drift between communication nodes makes communications unreliable.
