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: Fine Time Measurement (FTM) improvement and, specifically, trigger based FTM improvements via efficiently grouping initiators may be provided. A plurality of probe requests transmitted by a plurality of initiators is received. For each probe request, a Received Signal Strength Indication (RSSI) and Channel State Information (CSI) is determined, and a distance between an initiator and an associated responder associated with the probe request is determined based on the RSSI and the CSI. Line of Sight (LOS) or Non Line of Sight (NLOS) relationships between the plurality of initiators and one or more responders is determined based on the CSI. One or more groups of initiators is determined from the plurality of initiators based on the LOS or NLOS relationships and the distances determined for each probe request, wherein the responders and the initiators perform FTM based on the one or more groups of initiators.

Abstract: In one embodiment, a system for allocating clients between radios of an access point is disclosed. The system includes a first antenna coupled to a first radio, a second antenna coupled to a second radio, and a monitoring radio coupled to the first antenna and second antenna. The system includes computer-readable instructions that cause the system to receive at the monitoring radio, a first client attribute from each of a plurality of first client devices, and a second client attribute from each of a plurality of second client devices, and provide each aforementioned attribute to an optimization function. The system determines, with the optimization function, that one of the first radio and second radio will optimize performance for at least one device of the plurality of first client devices and second client devices and steer the at least one device accordingly.

Abstract: A network of access points (AP) in a high-density environment may be provided. A number of packet transmission retries for one or more of the AP may be determined by setting a number, m, of retries for transmitting a data packet, where m is the upper limit of the number of retries. Data packets are then transmitted m times. Upon transmitting the data packet m times, a success probability SP(u,m) for transmission of the data packet, where u is the number of users, may be calculated. The transmission of the data packet may be repeated m−x times where x is an integer. Upon calculating the success probability for m−x times, a success probability SP(u,m−x) for transmission of the data packet may be calculated. If SP (u,m−x) is larger than SP(u,m) then x may be decreased by one and actions (b)-(f) may be repeated. If SP (u,m−x) is not larger than SP(u,m) then m−x may be set as the maximum number of retries for the data packet.

A plurality of edge computing devices available to execute a computing task for a client device is identified, and a first latency of transmitting data among the plurality of edge computing devices is determined. A second latency of transmitting data from the client device to the plurality of edge computing devices is determined, and a set of edge computing devices, from the plurality of edge computing devices, is determined to execute the computing task based at least in part on the first and second latencies. Execution of the computing task is facilitated using the set of edge computing devices, where the client device transmits a portion of the computing task directly to each edge computing device of the set of edge computing devices.
