Method and System for Analyzing Radio Performance During Over-the-Air Operation

摘要

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.

1. An apparatus for identifying failed or suspect radio-frequency (RF) transmitting devices while the radio-frequency transmitting devices are in normal operation transmitting over-the-air RF signals, each of the radio-frequency transmitting devices including an identifier, the apparatus comprising:
at least one RF signal sensor receiving the RF signals from at least one of the radio-frequency transmitting devices that are mobile or portable, the at least one sensor responsive to the received RF signals; an analyzer:
determining RF frequency characteristics of the received RF signals from the at least one transmitting device;determining the respective identifier of the at least one transmitting device from the received RF signals; andusing the identifier from the received RF signals to correlate the RF frequency characteristics of the particular one of the transmitting devices; and a graphical user interface displaying 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.
