Abstract: This technology allows for determining the location of client devices via radio scanning for triggered orthogonal frequency-division multiple access (“OFDMA”) uplinks. Access points (“APs”) are configured for OFDMA transmissions. A first AP transmits a trigger frame on particular channel to stations in the wireless network. Neighboring APs scan channels for trigger frames (“TF”). Upon detection of a TF, neighboring APs associate a station identifier with a frequency allocation, or resource unit, in the TF. The neighboring APs receive an OFDMA uplink from the stations, determine a received signal strength indicator (“RSSI”) value for each frequency allocation in the OFDMA uplink, and transmit the RSSI values with the associated station identifier to the first AP. The first AP determines the location of each station by mapping a distance value to the RSSI values.

Abstract: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

Abstract: Methods and systems for distinguishing between radar signals and Wi-Fi signals are provided. When a set of electromagnetic signals are received, various tests are performed on the signals to determine if the signals are associated with radar pulses or if the signals are more likely to be associated with stray WI-Fi signals or other non-radar interference. One such test relies on the relatively small variance of frequencies used by radar pulses when compared to the high variation of Wi-Fi signals. Another test relies on the relatively low peak to average power ratio of signals associated with radar pulses when compared to Wi-Fi signals. The tests described herein are an improvement on existing methods for distinguishing radar signals from Wi-Fi signals and result in less switching of Wi-Fi channels due to erroneously detected radar signals.
