Abstract: Systems and methods are provided for learning radio frequency pulses transmitted at various frequencies in a wireless environment, including false radar signals and actual radar. For example, the system can keep a list of radio frequency pulse characteristics detected by access points (APs) but ignored when not declared a radar. The detected radio frequency pulse can be compared with those on the list and may be added to the deny-list if not radar. The AP learns what intervals are normal for the communication environment and if the noise someday looks like a real radar (but it not actually a radar), it will not be classified as radar because it is on the deny-list.

Abstract: Examples of techniques for handling multiple fine time measurement ranging requests are described. In an example, an access point (AP) may receive a ranging request for initiating an FTM session from each client device in a set of client devices. Based on the ranging request, a plurality of burst durations, each for performing the FTM session for each client device is determined. A maximum burst duration may be determined form the plurality. If a service time for serving high priority traffic is less than the maximum burst duration, a subset of the client devices is selected for performing the FTM session, where a sum of burst durations for performing the FTM session for each client device in the subset is less than the maximum burst duration. The FTM session for each client device in the subset is initiated.

Abstract: Operation of a wireless network access point (AP) to communicate with a first set of one or more wireless client devices using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable basic service set (BSS) identifier of the wireless AP. The BSS identifier is utilized to identify overlapping BSSs (OBSSs). A first set of one or more wireless client devices communicate using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable BSS identifier of the wireless AP. The BSS identifier is utilized to identify OBSSs. Unauthorized network activity is detected based on the BSS identifier and a received BSS identifier associated with the received transmissions. A dynamic adjustment is made to one of the BSS identifiers of the AP or the received BSS identifier in response to detected unauthorized network activity.

Abstract: A method for determining presence of a radar includes receiving a plurality of bursts in a dynamic frequency selection (DFS) channel of an access point, storing the plurality of bursts in a queue, in response to the queue comprising a threshold amount of bursts, determining a timespan of a first burst in the queue to a last burst in the queue, partitioning the timespan into at least a first group and a second group, determining a first number of bursts present in the first group and a second number of bursts present in the second group, in response to a difference between the first number of bursts and the second number of bursts equaling more than one, determining the radar is not present, and in response to the difference between the first number of bursts and the second number of bursts equaling one or less, determining radar is present.

Abstract: Embodiments are directed to intelligent scheduling of Wi-Fi services for applications. An embodiment of computer-readable storage mediums includes instructions for receiving data packets from multiple connected devices at a wireless access point and identifying an application traffic flow for each data packet; assigning each data packet to a respective queue of a first set of queues based on an identified application traffic flow for each data packet; selecting data packets from the first set of queues based on priorities for each of multiple applications; generating prioritized candidate lists for selected data packets in a second set of queues, each queue being dedicated for an access category for one or more application; and scheduling data packets from the candidate lists, including selecting a transmission mode for each access category based on characteristics of the one or more applications.
