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: 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.

Abstract: Aspects described herein include an exclusionary approach for basic service set (BSS) color selection and assignment in a network. A network controller for a network selects a radio associated with an access point (AP) under management of the network controller and determines a potential set of BSS colors for the radio. The network controller then removes/excludes a set of BSS colors that impacts the radio from the potential set of BSS colors and updates or assigns a BSS color for the selected radio using the potential set of BSS colors, minimizing the chances that the assigned BSS color will cause an overlapping BSS color condition in the network.

Abstract: Aspects described herein include a method for use with an access point (AP). The method comprises inspecting control frames received from a rogue AP, characterizing an intrusion by the rogue AP using one or more spatial reuse parameters included in the control frames, and selecting a defensive posture for the AP based on the characterization.
