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

Abstract

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.
