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.

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: When the loss or theft of a mobile device is detected, script interpretation logic executes a script to disable one or more functions or the mobile device, such as personal organizer functions in the mobile device. The script may be stored locally on the mobile device, so that the mobile device detects loss or theft and then executes the local disabling script. Alternatively, the script may be stored at a service provider and may be sent to the mobile device when loss or theft of the mobile device is detected or reported. The script may, for example, include instructions to encrypt private data on the mobile device, to send the private data to a data storehouse, and/or to otherwise disable one or more of the personal organizer functions of the mobile device.

Abstract: A radio access network has a reverse link frequency band for receiving signals from mobile stations and has first and second forward link frequency bands for transmitting signals to mobile stations. The second forward link frequency band has a greater frequency bandwidth than the first forward link frequency band and occupies a different part of the radio frequency spectrum. For certain types of communication sessions, such as voice and low-speed data, the reverse link frequency band and the first forward link frequency band are used. For other types of communication sessions, such as high-speed data and streaming video, the reverse link frequency band and the second forward link frequency band are used.

Abstract: A network entity, such as a base station, a mobile switching center, or a packet data serving node, may be communicatively coupled to at least two transmission paths, at least one of which is a wireless link. The network entity may receive signals from wireless terminals and output the signals to a first transmission path, i.e., a wireless link, or to a second transmission path, i.e., a wired link or another wireless link. The network entity may output the signals to the first transmission path or the second transmission path based on whether or not the measure of spectral interference for the wireless link meets predetermined criteria.

Abstract: Base stations exchange information with users over first wireless communication links. A mobile switching center provides mobile telephone service. An Internet access system provides Internet access service. A data system provides a data service. An Ethernet backhaul system uses an Ethernet format to exchange the information between the base stations and the mobile switching center, the Internet access system, and the data system. Wireless interfaces are coupled to the base stations and are configured to exchange the information over second wireless links. Individual base stations detect a fault in the Ethernet backhaul system, and in response, to route the information away from the Ethernet backhaul system and to the wireless interfaces to provide service restoration.

Abstract: A wireless communication system includes first and second communication systems and a controller. The first communication system receives a first control signal indicating a first power level and receives first communications. The first communication system formats the first communications into a first communication signal having the first power level and a first communication protocol, and transfers the first communication signal. The second communication system receives a second control signal indicating a second power level and receives second communications. The second communication system formats the second communications into a second communication signal having the second power level and a second communication protocol, and transfers the second communication signal. The controller transfers the control signals, and combines the first communication signal and the second communication signal to form a wireless communication signal, and transfers the wireless communication signal.
