    Abstract: Disclosed herein are methods and systems that may help a base station provide high-speed data communication under a protocol such as LTE or WiMAX, even when a GPS signal is not available to the base station. In an exemplary embodiment, a base station may acquire a high-stability reference signal via a subcarrier of a terrestrial broadcast signal, such as an FM radio signal, and may coordinate the timing frame transmissions with other nearby base stations, instead of relying upon a GPS signal for such functionality.

    Abstract: Disclosed herein are methods and systems that may help a WiMAX base station function without a GPS signal by providing a high-stability reference signal via a subcarrier of a broadcast signal, such as an FM radio signal. An exemplary broadcast station may therefore be configured to phase-lock a subcarrier signal to a GPS signal, and include this subcarrier in its broadcast signal, thereby providing the subcarrier signal for use by a base station as a high-stability reference signal for local-oscillator stabilization at the base station. The broadcast station may further modulate a timing signal onto the subcarrier signal. An exemplary base station may therefore receive the broadcast signal, decode the broadcast signal to acquire the subcarrier signal, and use the subcarrier signal to stabilize its local oscillator, rather than using a GPS signal. The base station may further demodulate the subcarrier to acquire the timing signal, which the base station may use for frame-start synchronization, instead of a GPS signal.

    Abstract: Exemplary methods and systems may generally be implemented to allow a macro-network base station without access to a GPS reference signal to provide some or all of the functionality for which existing macro-network base stations typically rely on GPS. In a first aspect, an exemplary macro-network base station may determine its location using a location-determination technique that is based upon the angles of arrival of FM radio signals from nearby FM stations. In a second aspect, an exemplary macro-network base station may stabilize its local oscillator by phase-locking its local oscillator to an FM radio signal, and periodically adjusting its local oscillator to account for phase drift of the FM radio signal. And in a third aspect, an exemplary macro-network base station may synchronize its frame-start timing with a nearby base station using a frame-start timing signal that the base station has synchronized to frame transmissions from the nearby base station during a setup routine.

    Abstract: Disclosed herein is a method and system for extending MIMO service in a wireless communications system. The system comprises a base station, a remote system, and a host system communicatively coupled to the base station and the remote system. The base station is configured to generate, from a baseband signal, a downlink signal comprising a plurality of downlink signal streams, including at least a first downlink signal stream and a second downlink signal stream. Accordingly, the base station may include a first and a second antenna that are configured to transmit the first and second downlink signal streams, respectively. The remote system provides wireless service in a remote coverage area. Further, the remote system is configured to transmit a downlink signal as a plurality of downlink signal streams. The host system is communicatively coupled to the base station and to the remote system and configured to relay the downlink signal streams from the base station to the remote system.
