A device for estimating a likelihood of a wireless link outage includes a
memory, a variability calculator, and an outage predictor. The memory
maintains a history of signal quality for a signal received from a
transmitter. The variability calculator is coupled to the memory. The
variability calculator computes a variability statistic for the history
of signal quality maintained in the memory. The outage predictor is
coupled to the variability calculator. The outage predictor estimates the
likelihood of the wireless link outage in direct proportion to the
variability statistic.
