Patent number: 8532024Abstract: A method and apparatus is provided for determining coupled path loss in a small geographical which is served by a plurality of transmitters and is subject to broad signal level variation. A method is also provided for determining performance of a signal received by a wireless device located within a bin of a cell of a cellular communication system. The method comprises determining the value of the received signal level as a function of the sum of the signal levels received from a primary base station at a primary cell divided by a number of signal level measurements from the primary base station.Type: GrantFiled: May 17, 2006Date of Patent: September 10, 2013Assignee: Andrew LLCInventors: John Arpee, John Peter Carlson

Publication number: 20110230206Abstract: A system and method for determining a position of a wireless mobile device. The method comprising the steps of providing one base station in communication with the mobile device, providing a sensor spaced apart a known distance from the base station, and determining the range between the mobile device and the base station. The time of arrival of a signal transmitted from the mobile device is measured at the sensor and a set of coordinates is calculated for the mobile device relative to the sensor as a function of the known distance from the sensor to the base station, the range between the mobile device and the base station, an estimate of base station transmission timing relative to a time source, and the time of arrival. One of the set of coordinates may then be chosen to thereby determine a position of the mobile device relative to the sensor.Type: ApplicationFiled: May 31, 2011Publication date: September 22, 2011Applicant: Andrew, LLCInventors: Joseph P.

Patent number: 7925205Abstract: A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters is disclosed. Embodiments of the novel system and method enable wireless communication system to determine if signals being received by system receivers arrive directly from a target mobile appliance or if the signals are passing through a repeater. The system's determination may be based at least in part on the TA of the signal, the power of the received signal, the power of the transmitted signal, the hearabiltiy of the signal at system receivers, the hearabiltiy of system transmitters at the mobile and the known delays associated with the repeaters. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.Type: GrantFiled: September 17, 2004Date of Patent: April 12, 2011Assignee: Andrew LLCInventors: Joseph P. Kennedy, Jr., John Peter Carlson, Thomas B. Gravely, Andrew Beck

Patent number: 7804786Abstract: The instant disclosure generally relates to a method and apparatus for determining path loss by combining geolocation with interference suppression. In one embodiment, the disclosure relates to a method for determining a path loss value between a receiver at a first location and a wireless mobile device at a second location. The method includes the steps of: (a) locating the mobile device at the second location and (b) at the receiver: (i) receiving a first signal transmitted by the mobile device at the second location; (ii) determining a received signal level of the first signal; (iii) receiving a second signal comprising data from which a transmitted signal level of the mobile device at the second location can be determined; and (iv) determining from the first and second signals the path loss value between the receiver and the mobile device at the second location.Type: GrantFiled: May 17, 2006Date of Patent: September 28, 2010Assignee: Andrew, LLCInventors: John Peter Carlson, John Arpee

Patent number: 7738836Abstract: A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters is disclosed. Embodiments of the novel system and method enable a wireless communication system to determine if signals being received by system receivers arrive directly from a target mobile appliance or if the signals are passing through or via a repeater. In an embodiment, the system's repeaters use a co-channel AM Golay Hadamard sequence multiplied by an uplink signal to watermark the repeated signal. The system uses the known AM Golay Hadamard sequences of the repeaters and the waveform of the received uplink signal to detect whether a repeater has operated on the signal and which repeater operated on the uplink signal. Embodiments of the novel system and method provide system management data and can be used to provide more accurate geolocation of mobiles served by repeater stations.Type: GrantFiled: September 24, 2004Date of Patent: June 15, 2010Assignee: Andrew CorporationInventors: Martin Alles, Joseph P.

Patent number: 7429914Abstract: A system and method is disclosed for determining the location of a mobile appliance using the reverse pilot channel provided in CDMA 2000 communication systems to determine an attribute (e.g., time of arrival, angle of arrival, time difference of arrival, received power level) of a reverse pilot signal at one or more wireless location sensors. A network overlay of wireless location sensors monitors the reverse pilot channel for a target mobile's reverse pilot signal. The monitored signal may be compared to a reference signal to determine a correlation and thereby determine an attribute of the target mobile's reverse pilot signal. The method may be performed independently from the communication system and without requiring retrieval of information bits from the mobile appliance. The reference signal may be generated from the unique long spreading code mask of the target mobile appliance which is typically a function of the ESN of the target mobile appliance.Type: GrantFiled: December 10, 2004Date of Patent: September 30, 2008Assignee: Andrew CorporationInventors: John Peter Carlson, Thomas Booker Gravely, Joseph P.

Patent number: 6845240Abstract: A system and method for determining the geolocation of autonomous mobile appliances emitting analog waveforms is disclosed. More specifically, the inventive system and method is used to geolocate FM analog signals such as those used in the AMPS cellular radio air standard by using a time difference of arrival (“TDOA”) approach. The inventive system and method uses a novel approach to minimize the amount of data sent between location sensors and the central location processor comprising adaptive signal combining from N channel to a single channel, FM demodulation to reduce bandwidth, Fourier transformation for signal compression, and segmentation of the location sensors into primary and secondary modes to allow for parallel processing to ease the computational burden on the central location processor.Type: GrantFiled: December 11, 2001Date of Patent: January 18, 2005Assignee: Grayson WirelessInventors: John Peter Carlson, Thomas Booker Gravely, Joseph P.
