Abstract: An antenna comprising a plurality of sub-arrays and methods and structure for restoring performance after a transceiver failure is provided. Each sub-array may include a power divider/combiner network, a first radiating element coupled to a first port of the power divider/combiner network, a second radiating element coupled to a second port of the power divider/combiner network, and a transceiver coupled to a third port of the power divider/combiner network. An adjustable power supply may be coupled to each transceiver, the adjustable power supply having current monitors to detect at least one failure state of a transceiver, and a power compensation mode to increase absolute power to a transceiver in a non-failed state. The adjustable power supply provides a first voltage in normal operation and a second voltage, where the second voltage is higher than the first voltage in power compensation mode.

Abstract: A method of modifying calibration data used to geo-locate a mobile station located in an indoor environment is disclosed. When a mobile station is located indoors, the signal strength of signals received and/or transmitted by the mobile station have the tendency to be lower than the strength of the signals received by a mobile station located outdoors. As a result of these lower signal strengths, geo-location efforts which rely on signal strengths may result in unsatisfactory location accuracy. Modifying pre-existing calibration data obtained outdoors may provide a way to simulate indoor calibration data characteristics.

Abstract: A method is provided for processing emergency service calls from a user device to a PSAP, the user device having an associated line number and being configured to originate calls from fixed and mobile access networks. The method includes determining whether a call from the user device originates from a home location in a fixed access network. When the call is determined to have originated from the home location in the fixed access network, the call is routed to the PSAP, where a location of the user device is determined based on the Automatic Number Identification (ANI) included in signaling associated with the call. When the call is determined not to have originated from the home location in the fixed access network, adding pseudo-ANI to signaling associated with the call and routing the call to the PSAP, where the location of the user device is determined based on the pANI.

Abstract: A method and system for determining the location of a mobile device in a communications network or the proximity of the device to a node in the network. A location request may be received for a mobile device served by a base station in the network. A set of nodes associated with the serving base station may then be tasked and downlink data collected at a first node, the downlink data from a downlink signal received from the serving base station. Downlink frame timing may then be determined as a function of the collected downlink data and uplink data collected at a second node as a function of the determined downlink frame timing. A geographic location for the device or proximity thereof to a node may be determined as a function of the collected uplink data.

The factors can include the bandwidth of the signal that the digitized signal represents, the amount of bandwidth owned or used by the carrier, the full bandwidth of the designated RF band, the bandwidth of the serial link, the frame length of the serial link, the segmentation of the frames on the serial link, and the capability of the equipment at the receiving end of a serial link. The re-sampled signal can be transmitted to another unit that is remote to the unit transmitting the signal. The other unit can include a re-sampling device that restores the re-sampled signal to a digital signal that can be converted to an analog signal for wireless transmission.

Abstract: A distributed antenna system having improved data transmission features incorporates endpoints of the system, which are coupled together by serial data link. At the endpoints, processing may occur utilizing processing circuitry to determine similarities between multiple signal streams. If the streams are similar, the data sent over the serial digital link is reduced by only sending one of the representative signals. In an alternative embodiment of the invention, the difference between the signals might be sent as well. Alternatively, all signals might be sent, but may be compressed with compression circuitry before the signals are transmitted over the serial link. At the endpoint of the system, the signals are reconstructed for further processing and transmission.

The adaptive cancellation circuit is configured to generate a cancellation signal without requiring an injected signal. The cancellation signal, when added to a radio frequency signal in the respective uplink and downlink paths, substantially reduces feedback signals present in the radio frequency signal.
