Method and system for analyzing radio performance during over-the-air operation

摘要

An apparatus for determining operating characteristics of radio-frequency (RF) transmitting devices while the devices are in normal operation transmitting over-the-air RF signals. The apparatus comprises at least one signal sensor for receiving the RF signals, each sensor responsive to the RF signals received at a plurality of antennas or received at a directional antenna, an analyzer for determining signal parameters of received RF signals and for determining operating characteristics of the transmitting devices from the signal parameters, wherein each RF signal includes an identifier of the transmitting device, the apparatus using the identifier to link operating characteristics determined from the RF signals to the transmitting device, and a graphical user interface for displaying the operating characteristics for each transmitting device.

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 at least one of waveform visualization information and bit-field visualization information 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 at least one waveform visualization information and bit-field visualization information of the particular one of the transmitting devices; and a graphical user interface displaying at least one of the waveform visualization information and the bit-field visualization information in a form that can be used to identify transmitting devices that have failed and transmitting devices that are suspect.
