Abstract:
1. A method to provide maintenance to a receiver, comprising: determining a time series of test quantities for receiver, the test quantities based on signal strength measurements collected at the receiver at a plurality of time instances; receiving a figure of merit for the receiver, the figure of merit indicating an expected signal quality for the receiver; eliminating the receiver as a candidate for failure prediction if the time series of test quantities does not trend downward for a predetermined number of time instances; eliminating the receiver as a candidate for failure prediction if the time series of test quantities is not below the figure of merit for a predetermined period of time; determining a failure prediction for the receiver based on the time series of test quantities and the figure of merit, the act of determining the failure prediction only performed if the receiver is not eliminated as a candidate for failure prediction; and identifying the receiver for maintenance if the failure prediction indicates a future unacceptable signal strength for the receiver.
