Synchronizing the local time of beacons using two way time transfer methods and hardware enabling such methods. Certain systems incorporate receive hardware into beacon circuitry used for transmitting signals so that the beacon can transmit RF signals during transmission periods, and can also receive RF signals from other beacons during non-transmission periods. Receive hardware may be incorporated into beacon circuitry such that the beacon receives an incoming signal and passes that incoming signal to a digital pre-distortion linearization module, which can process that received signal. Methods for controlling whether a beacon transmits RF signals or receives RF signals are also discussed, as are methods for using RF signals received from other beacons for synchronization.
