    Abstract: 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.

    Abstract: In an example, a method for correcting time-of-flight measurements includes receiving a plurality of time-of-flight measurements and determining whether the time-of-flight measurements relate to a strong signal client, a weak signal client, or a preferred signal client. If the time-of-flight measurements relate to a strong signal client or a weak signal client, the method determines whether the time-of-flight measurements constitute two distinct distributions. If the time-of-flight measurements constitute two distinct distributions, a mean value for each distribution is determined. If the mean values differ by a predetermined time delay attributable to automatic gain control processing, the time-of-flight measurements corresponding to the distribution having the lower mean value are used. If the mean values differ by less than the predetermined time delay attributable to automatic gain control processing, the time-of-flight measurements corresponding to both distributions are used.
