摘要
Methods and systems are provided for implementing an alternative timing source for low-cost-Internet-base-station-(LCIB) systems. In accordance with an embodiment, an LCIB has an internal clock. The LCIB is arranged to receive a GPS signal, and to treat timing information embedded in the GPS signal as the LCIB's primary source of timing information for calibrating the internal clock. The LCIB detects a loss of the GPS signal, and responsively uses a macro-network receiver to receive macro-network timing information from a macro network, which is a terrestrial wireless network. The LCIB uses the macro-network timing information to calibrate the internal clock.
