Abstract: Dynamic spectrum access mode based on station capabilities is provided by categorizing functionalities of Access Points (APs) and mobile stations (STA) in a wireless network; identifying interference induced by external signaling devices on channels in the wireless network; calculating an impact factor of the interference based on proximity of the external signaling devices to the wireless network, a pattern of the external signaling devices, and an extent of overlap with frequencies used by the external signaling devices and the wireless network; and in response to identifying a given STA that is paired with a given AP in the wireless network, wherein the given STA and the given AP are both categorized as being capable of both multilink communications and preamble puncturing, assigning network resources for the given STA to communicate with the given AP via one of multilink communications or preamble puncturing based on the impact factor of the interference.

Abstract: Network environment health monitoring is provided by receiving an alert indicating that a first station (STA) is experiencing a connection with a first Access Point (AP) below a quality threshold; identifying a set of APs connected to a shared network with the first AP within one hop of the first AP; aggregating signal metrics for the first STA from the first AP and each AP of the set of APs; identifying a cause for the connection performing below the quality threshold based on the signal metrics as aggregated; and performing a remediation strategy based on the cause as identified.

Abstract: Flexible radio assignment with beamsteering antennas is provided by controlling a plurality of Access Points (APs) including steerable antennas to each transmit a first plurality of discovery frames at a first beamwidth; controlling the plurality of APs to steer the steerable antennas at a second beamwidth, less than the first beamwidth, to a plurality of steering angles; controlling the plurality of APs to each transmit a second plurality of discovery frames at each steering angle of the plurality of steering angles; determining an overlap in radio coverage among the plurality of APs based on the first plurality and the second plurality of discovery frames; and identifying redundant radios based on the overlap in radio coverage; and reassigning the redundant radios from use for client transmissions to a secondary role.

Abstract: A network system comprises a plurality of access points (APs) and a distributed cache. The distributed cache is formed using memory in the plurality of APs. The plurality of APs are configured to measure telemetry data and store the telemetry data in the distributed cache. One of the plurality of APs is assigned as a controller AP configured to assign, based on the telemetry data stored in the distributed cache, multiple APs of the plurality of APs to different roles to analyze the plurality of APs and update resource configurations of the plurality of APs.

Abstract: Techniques are disclosed for determining, at a first wireless access point (AP), one or more radio resource management (RRM) input parameters. The one or more RRM input parameters are determined based on a line of sight (LOS) estimate between two wireless stations (STAs). A plurality of RRM values are generated based on the one or more RRM input parameters. A wireless connection is established between the first AP and a first STA using the RRM values.
