Abstract
Technologies directed to rate adaption based on both the average signal-to-noise ratio (SNR) and standard deviation are described. One method includes determining an average SNR value and a standard deviation value for a first set of RSSI samples. The method determines whether the average SNR value satisfies a first threshold criterion corresponding to a minimum SNR required with a first modulation scheme and a second threshold criterion corresponding to a standard deviation threshold. The method causes a transmitter to use the first modulation scheme for a subsequent packet, responsive to the average SNR value satisfying the first threshold criterion or the standard deviation value satisfying the second threshold criterion. The method causes the transmitter to use the second modulation scheme for the subsequent packet, responsive to the average SNR value not satisfying the first threshold criterion and the standard deviation value not satisfying the second threshold criterion.
