1. A receiving device for mitigating a predicted wireless link outage, the receiving device comprising:
- a memory to maintain a history of signal quality for a received signal;
a variability calculator coupled to the memory, the variability calculator to compute a variability statistic for the history of signal quality maintained in the memory; and
,an outage predictor coupled to the variability calculator, the outage predictor to increase the size of a receive buffer if the variability statistic is above a predetermined threshold.

Abstract
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.
