Abstract: An apparatus determining characteristics of radios within a communications network includes a radio, RF signal sensor, analyzer, and computer. The radio transmits RF signals, has transmission operating parameters with respective predetermined values having respective thresholds and a identifier, and has an air operating mode where signals comprise the identifier. The sensor receives the signals having characteristics correlating with the operating parameters. While the signals are received during the operating mode, the analyzer measures the signal characteristics and determines health of the radio by analyzing whether the measured characteristics transmitted are within the respective thresholds of the values, and concludes that health is acceptable if the measured characteristics are within the thresholds, and concludes that health is unacceptable if at least one measured characteristic is outside a threshold.

Abstract: An apparatus determining network health comprising base stations in bidirectional communication with radios, each having an identifier and transmitting a signal including the identifier. First and second health determining radios each receive the signal during normal over-the-air operation of radio and determine if the radio is authorized and, if so, determine the identifier, time-separated signal waveforms that are compared, operating characteristics from the compared waveforms, and a current location of the radio. Each of the radios determine health of the radio based on packet sniffing, a frequency deviation, or a range of deviations by analyzing the operating characteristics. After analysis results sent to the master controller from the radios indicate that the authorized radio is healthy, the master controller determines from the analysis results that a geographically unhealthy location of the network exists within the geographic area from which the authorized healthy radio transmitted the signal.
