  • Patent number: 7577398
    Abstract: A flat-panel repeater includes a housing having a pair of oppositely facing surfaces, at least one antenna element mounted to each of the surfaces for radiating energy in a direction opposite to that of an antenna element mounted to the other of the surfaces, and an electronic circuit mounted within the housing and operatively coupling signals between at least one antenna element on each of the oppositely facing surfaces of the module. Isolation between the antennas on opposite sides of the repeater is improved by various techniques, such as use of adaptive cancellation which removes a significant portion of the feedback signal power, therefore increasing the total system isolation by the same amount. This additional isolation can be used to achieve greater system gain, and therefore significantly extend the range of the system.

  • Publication number: 20090186521
    Abstract: A coaxial connector includes a clamp nut dimensioned to fit over the outer conductor, the clamp nut having threads that mate with corresponding threads on the connector body. A clamp element is positioned between the clamp nut and a leading edge of the outer conductor. The connector body having an annular wedge surface dimensioned to mate with the leading edge of the outer conductor. The threads draw the clamp nut towards the connector body, to clamp the leading edge between the clamp element and the annular wedge surface. A surface-to-surface positive stop between the clamp nut and the connector body limits the compression force to a predetermined maximum by preventing further movement of the clamp nut towards the connector body. A thread lock is engaged as the positive stop is reached; the thread lock inhibiting unthreading of the clamp nut from the connector body.

  • Patent number: 7561104
    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.

  • Patent number: 7546084
    Abstract: A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters (350a, 350b) is disclosed. Embodiments of the novel system and method enable the geolocation system to determine if signals being received by the geolocation system arrive directly from a target mobile appliance or if the signals are passing through a repeater (350a, 350b) and therefore are subject to a known time delay. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.

  • Patent number: 7541868
    Abstract: A circuit for pre-distorting a signal input to an amplifier includes a signal divider operable for dividing an input signal into signal portions that travel in a primary path and a secondary path. A delay element in each of the primary and secondary paths introduces a group delay to the signal portions in the respective paths. A signal combiner is operable for combining the signals in the respective paths into a combined output signal. A variable gain circuit is arranged in each of the primary and secondary paths. The variable gain circuit is operable to vary the level of the input signal in each path and thereby modulate the overall phase delay of the combined output signal.
