20100259448 | METHOD AND SYSTEM FOR HEALTH MONITORING OF AN OVER THE AIR GEO-LOCATION SYSTEM - A method for testing each one of a plurality of receiving sites operative in a time difference of arrival geo-location system. The method comprises determining a theoretical time of arrival of a test message at each receiving site assuming the test message was transmitted from a test message transmitting antenna at a known location; determining a measured time of arrival of the test message at each receiving site, the test message transmitted from the test message transmitting antenna; determining a true time of arrival of the test message at each receiving site, the true time of arrival comprising the measured time of arrival less a start time of the test message; determining a difference between the theoretical and the true times of arrival for each receiving site, wherein the difference for each receiving site is indicative of a health of the receiving site. | 10-14-2010 |
20110319029 | METHOD AND SYSTEM FOR DIAGNOSING RADIO PERFORMANCE DURING FUNCTIONAL OVER-THE-AIR OPERATION - An apparatus for determining a health of radio-frequency transmitters each transmitting a transmitted signal during normal operation. The apparatus comprises a receiver for receiving received signals, each received signal responsive to a transmitted signal, a first element for determining signal parameters of each received signal, the signal parameters responsive to an operating condition of a transmitter, each transmitted signal and each associated received signal including an identifier of the transmitter that transmitted the transmitted signal, the apparatus using the identifier to link determined signal parameters with the transmitter that transmitted the transmitted signal and a second element for determining a health of the transmitter that transmitted the transmitted signal, the health responsive to a relationship between one or more signal parameters and a selected value or a range of selected values for each signal parameter. | 12-29-2011 |
20120289242 | NETWORK DIAGNOSTIC SYSTEM FOR ANALYZING THE PERFORMANCE OF A RADIO NETWORK DURING FUNCTIONAL OVER-THE-AIR OPERATION - An apparatus for determining network health, the network comprising a plurality of network base station transceivers in bidirectional communication with radios operating in the network, a first radio transmitting a transmitted signal. The apparatus comprises first and second devices for determining respective first and second signal parameters of respective first and second received signals, the first and second received signals responsive to the transmitted signal transmitted during normal over-the-air operation of the first radio, wherein the received signal received at the first receiver is time aligned with the received signal received at the second receiver to ensure the first and second devices determine the first and second signal parameters of the same transmitted signal and wherein the network health is responsive to the first and second signal parameters. | 11-15-2012 |
20140092949 | Method and System for Diagnosing Radio Performance During Functional Over-the-Air Operation - An apparatus for determining a health of radio-frequency transmitters each transmitting a transmitted signal during normal operation. The apparatus comprises a receiver for receiving received signals, each received signal responsive to a transmitted signal, a first element for determining signal parameters of each received signal, the signal parameters responsive to an operating condition of a transmitter, each transmitted signal and each associated received signal including an identifier of the transmitter that transmitted the transmitted signal, the apparatus using the identifier to link determined signal parameters with the transmitter that transmitted the transmitted signal and a second element for determining a health of the transmitter that transmitted the transmitted signal, the health responsive to a relationship between one or more signal parameters and a selected value or a range of selected values for each signal parameter. | 04-03-2014 |
20140308904 | NETWORK DIAGNOSTIC SYSTEM FOR ANALYZING PERFORMANCE OF A RADIO NETWORK DURING FUNCTIONAL OVER-THE-AIR OPERATION - An apparatus determining network health in a network comprising base station transceivers in bidirectional communication with radios, each having an identifier and transmitting a signal including the identifier. First and second devices each receive the transmitted signal during normal over-the-air operation of the radio, measure signal parameters, and determine operating characteristics of the radio from the parameters. Each of the devices produce a responsive received signal when the first operating characteristics determined by the first device indicate a healthy first radio and the second device produces a responsive received signal when the second operating characteristics determined by the second device indicate a healthy first radio. The devices determine respective signal parameters of the respective received signals. The received signals are time aligned to insure that the devices have determined the respective signal parameters of the same transmitted signal. Network health is indicated by the first and second operating characteristics. | 10-16-2014 |

A location server that uses a processor to: push and/or pull tracking information controlled by the hierarchy; push and/or pull other forms of information exchange between devices and controlled by the hierarchy; control a dissemination of information between devices running the tracking application and/or information exchange application based on the hierarchy; and control the dissemination of information between devices running the tracking application and/or information exchange application based on location. | 02-26-2015 |
20150105030 | Method and System for Analyzing Radio Performance During Over-the-Air Operation - An apparatus for identifying failed or suspect RF transmitting devices while the devices are in normal operation transmitting over-the-air RF signals. The apparatus comprises an RF signal sensor receiving the RF signals from at least one of the devices that are mobile or portable. The sensor is responsive to the received RF signals. An analyzer determines RF frequency characteristics of the received RF signals from the at least one transmitting device, determines the respective identifier of the at least one transmitting device from the received RF signals, and uses the identifier from the received RF signals to correlate the RF frequency characteristics of the particular one of the transmitting devices. A graphical user interface displays at least one RF frequency characteristic in a form that can be used to identify transmitting devices that have failed and transmitting devices that are suspect. | 04-16-2015 |
