Abstract: A system and method for determining the location of a wireless device. A boundary for an approximate area in which the wireless device is located is determined and a plurality of satellites may be determined as a function of the boundary. Assistance data is transmitted to the device which includes information from the plurality of satellites, and the location of the wireless device may be determined from the information. In one embodiment, if the number of the plurality of satellites is greater than a predetermined threshold then the number of satellites may be reduced as a function of one or more of the elevation of each satellite above the horizon, a distance between each satellite to one or more other satellites, and an altitude of each satellite.

Abstract: A method and system for determining an approximate range from a location measurement unit to a mobile device. An uplink signal from the mobile device is received by the location measurement unit, and an uplink frame marker is determined from the uplink signal. A downlink signal is received at the location measurement unit from a base station serving the mobile device, and a downlink slot marker is determined from the downlink signal. A round trip propagation delay is determined based upon the uplink frame marker and the downlink slot marker, and an approximate range from the location measurement unit to the mobile device is determined as a function of the round trip propagation delay.

Abstract: The present invention relates to the operation and maintenance of radio base stations in mobile communication systems. An inventive radio base station, which can be upgraded remotely in a safe way. In one embodiment of the invention, the radio base station comprises a file system comprising different versions of files, so that an old version of a file can be reverted to should problems in the operation of the radio base station occur In another embodiment of the invention, the radio base station comprises a back-up area in which a copy of the files of the file system are stored. The back-up area is independent of the file system, so that if problems with the files in the file system are detected, the contents of the back-up area can be stored in the file system.

Abstract: A method for enabling a system to enhance the accuracy of a location estimate modifies weights in a weight matrix associated with receiver station measurements in parallel with successive refinements of the location estimate. In a typical location estimation scenario, several receiving stations simultaneously derive measurements of a signal from the emitter. Any one of these measurements is in general some function of the emitter location and the receiving station location. The aggregate of these measurements is often in excess of the minimum number of measurements required to provide an estimate of the emitter location. Where such an excess exists, the method proceeds by modifying the weights associated with the measurements in parallel with successive refinements of the location estimate. The method can be implemented over various cellular protocols with a consistent and significant enhancement in the accuracy of location estimates.

Abstract: A method for calibrating an antenna and signal processing system enabling angle of arrival (AOA) determination for a frequency hopping signal, in which a calibration coefficient is determined in response to one or more calibration signals injected into the system at one or more of the frequencies in the hopping sequence and proximate in time to reception of the communication signal. The calibration coefficients are reflective of a frequency and time dependent parameter of a path between the antenna and wireless location sensor. The AOA is determined as a function of the calibration coefficient and the radio frequency energy of the received communication signal. Several embodiment of the method are illustrated.

Abstract: A push-on connector interface adapted for use with, for example, existing standardized threaded female connectors, for example SMA or Type N connectors. A plurality of spring fingers of the male connector body engage the, typically threaded, outer diameter surface of the female connector body. A sleeve within the male connector body is adapted to extend within a bore of the female connector body. A spring located, for example, within a groove on the sleeve deforms between the sleeve and an inner diameter surface of a bore within the female connector body. The connections formed by the bias of spring fingers and the deformation of the spring creating a reliable mechanical and electrical interconnection between the male and female connector bodies without use of the prior threaded collar.
