Abstract: A cable end preparation tool is for a coaxial cable and has a C-shaped body with an opening therein to receive the coaxial cable and a side defining a saw guide to receive a saw blade thereagainst. The C-shaped body includes a gripping rib to fit in a valley of a corrugated outer conductor when the coaxial cable is in the opening. At least one stabilizing rib is adjacent the gripping rib to receive a crest of the corrugated outer conductor thereagainst when the coaxial cable is in the opening. The C-shaped body also includes a rotation guide feature receives the inner conductor. A cutting blade extends outwardly from the C-shaped body for removing a portion of a dielectric between the inner conductor and the corrugated outer conductor as the C-shaped body is rotated about the rotation guide feature.
Abstract: A method for detecting an IS-95 signal without knowledge of a spreading code for the IS-95 signal is provided. A received baseband signal is rotated through a plurality of phase-shifts. For each phase-shifted baseband signal, an in-phase component or a quadrature component of the phase-shifted baseband signal is realigned. The in-phase and quadrature components are multiplied by a PN short code to partially despread the components. The partially despread in-phase and quadrature components are multiplied and integrated. The integrated despread in-phase and quadrature components are compared to a threshold value. In response to exceeding the threshold value, the received baseband signal is identified as an IS-95 signal. The method may be implemented on a repeater for repeating signals between multiple sources.
Abstract: A system and method for determining a location of a wireless device in a communications network. A request for satellite assistance data may be received from a requesting entity, and a reference location determined as a function of the request. One or more characterizing attributes may be identified as a function of the reference location, and a set of satellites determined as a function of the reference location. It may also be determined whether more than one set of signal measurements should be acquired from one or more satellites in the set of satellites as a function of the identified one or more characterizing attributes. The one or more sets of signal measurements may be acquired, and a location of the wireless device determined from the acquired measurements.

The method includes receiving global navigation satellite system (GNSS) measurements from the mobile device, and receiving terrestrial measurements from corresponding transceivers in the wireless network, each terrestrial measurement indicating a distance between the corresponding transceivers and the mobile device. The method further includes selecting at least one terrestrial measurement having an uncertainty value within a predetermined accuracy threshold. The location of the mobile device is determined as a function of the GNSS measurements and the selected terrestrial measurement.
Abstract: A system and method for determining an approximate location of a mobile device. The occurrence of a predetermined event may be determined at a first node of a network. Measurement data associated with the mobile device may be stored at a second node of the network. An attempt may be made to determine a location of the mobile device using a first location methodology. Upon failure of the location attempt, the mobile device data may be received at a third node of the network from the second node. At the third node an approximate location of the mobile device may be determined using the mobile device data.

Abstract: A system and method for determining the location of a mobile device. A first set of signals from a plurality of radio frequency (“RF”) sources may be received at a mobile device and then downconverted into a second set of signals. The mobile device may then time stamp the second set of signals and transmit the time stamped signals to a location determining system. The location of the mobile device may be determined at the location determining system as a function of the time stamped signals.
Abstract: A method and system for estimating the location of a mobile device. A range of the mobile device to a reference station may be determined as a function of the time of transmission of a first signal transmitted from a base station and as a function of the time of receipt of a second signal transmitted from the mobile device to the reference station, the second signal being a function of the first signal advanced by a timing parameter. A relationship for each of a plurality of grid points in a geographic region may be determined as a function of the determined range and a range metric. These plural grid points may contain the reference station. The determined relationship may be compared with data corresponding to each of the plural grid points, and a location of the mobile device determined as a function of the comparison.

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: A clip for a snap-in cable hanger with a top from which at least two clip arm(s) extend and at least one of the clip arm(s) formed with a clip tab projecting proximate a distal end. The top having a length greater than a diameter of the mounting hole and a width dimensioned to fit within a spring space when the snap-in cable hanger is seated upon the mounting hole. The clip arm(s) spaced apart proximate the diameter of the mounting hole, having a length longer than a depth of the mounting hole.
Abstract: The present subject matter discloses a method for estimating dilution of precision (DOP) across a service area. A Monte Carlo simulation is used to determine the DOP across a service area. Random points are selected across a service area and as well as the radio transmitters who signals are capable of being received at the random points are determined. Using the network topology of radio transmitters, a DOP is calculated for each of the random points. DOP is modeled for the service area as a function of the calculated DOP for each of the random points. The modeled DOP is used to determined the measurement accuracy required for subsequent location requests.
