    Abstract: A method includes determining, based on a first packet error rate (PER) associated with a first communication data rate of data sent from a first electronic device to a second electronic device, a predicted second PER associated with a second communication data rate by increasing a value of the predicted second PER based on a first signal-to-noise ratio (SNR) sensitivity associated with the first communication data rate being less than a second SNR sensitivity associated with the second communication data rate or by decreasing the value of the predicted second PER based on the first SNR sensitivity being greater than the second SNR sensitivity. The method further includes selecting a communication data rate for communication from the first electronic device to the second electronic device based at least in part on the first PER and the predicted second PER.
