According to an example, motion-aware MCS adaptation may include determining whether a device is static relative to a wireless AP, moving towards the wireless AP, or moving away from the wireless AP. A device static rate probing interval, a device moving rate probing interval, first and second frame retransmission limits, a device static PER smoothing factor, and a device moving PER smoothing factor may be determined. In response to a determination that the device is static relative to the wireless AP, moving towards the wireless AP, or moving away from the wireless AP, an appropriate rate probing interval, an appropriate frame retransmission limit, and an appropriate PER smoothing factor may be used to determine a MCS value from a plurality of available MCS values to be used for transmitting data between the device and the wireless AP.
