Network diagnostic system for analyzing the performance of a radio network during functional over-the-air operation

摘要

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.

1. 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 and each having an identifier for the respective radio, a first radio transmitting a transmitted signal including a first identifier, the apparatus comprising:
first and second devices each receiving the transmitted signal during normal over-the-air operation of the first radio, measuring signal parameters of the transmitted signal, and determining first and second operating characteristics of the first radio from the respective signal parameters, the first device producing a first received signal responsive to the transmitted signal when the first operating characteristics determined by the first device indicate that the first radio is healthy and the second device producing a second received signal responsive to the transmitted signal when the second operating characteristics determined by the second device indicate that the first radio is healthy, the first and second devices determining respective first and second signal parameters of the respective first and second received signals; wherein the first received signal is time aligned with the second received signal to insure that the first and second devices have determined the respective first and second signal parameters of the same transmitted signal; and wherein the network health is indicated by the first and second operating characteristics.
