Abstract: Techniques and apparatus for configuring ultra-wideband (UWB) communications using out-of-band (OOB) mechanisms are described. An example technique performed by a wireless device includes obtaining, prior to association with an access point (AP), ultra-wideband (UWB) information from the AP via an out-of-band (OOB) communication link between the wireless device and the AP. A location server within a network including the wireless device and the AP is determined based on the UWB information. Configuration information associated with a UWB ranging session from the location server is obtained via the OOB communication link. The UWB ranging session is performed in accordance with the configuration information.

Abstract: Systems and techniques for mitigating interference to incumbent users in a wireless network are described. An example technique includes receiving an indication of interference on a channel that an incumbent user within a wireless network is operating on. A source of the interference is determined using key performance indicator(s), in response to the indication. A set of actions is determined and performed to mitigate the interference. Another example technique includes receiving an indication of interference on a channel that an incumbent user within a wireless network is operating on. Interference information is obtained from a controller associated with the wireless network and includes KPI(s) associated with a set of access points (APs) operating on the channel. A source of the interference is determined based on the interference information. A set of actions to mitigate the interference are determined and performed on one or more of the set of APs.

Abstract: Global Navigation Satellite System (GNSS) interference detection may be provided. A satellite tracking table for a first Access Point (AP) may be created. The satellite tracking table may include a listing of a plurality of satellites of a Global Navigation Satellite System (GNSS) available for the first AP and expected satellite parameters for each of the plurality of satellites. A derived satellite parameter may be determined from a received GNSS signal. The derived satellite parameter may be compared with an corresponding expected satellite parameter. The corresponding expected satellite parameter may be determined from the satellite tracking table. An interference event may be determined when the derived satellite parameter differs from the corresponding expected satellite parameter by at least a predetermined amount.

Abstract: Techniques for automated wireless deployment configuration are provided. Environmental sensor data from a plurality of access points (APs) is received, and the plurality of APs are clustered into a set of clusters based on the environmental sensor data. Cluster classifications are generated by classifying each cluster in the set of clusters as either an indoor cluster or an outdoor cluster based on the environmental sensor data and one or more defined environmental values. A respective label is assigned to each respective AP in the plurality of APs based on the cluster classifications, and one or more of the plurality of APs are reconfigured based on the assigned labels.

Abstract: Techniques for reducing wireless interference are provided. A wireless local area network (WLAN) is providing, by an access point using a first radio. It is determined to initiate a geolocation process for the access point using a second radio. A first amount of interference at the second radio caused by the first radio is determined, and either a hot start geolocation acquisition process or a cold start geolocation acquisition process is selectively used for the AP based on comparing the first amount of interference to one or more criteria.
