Abstract: Systems and methods are provided for optimizing channel bandwidth while increasing downlink multi-user, multiple-input, multiple-output (DL MU-MIMO) gain. Depending on the access point (AP) platform, for example, APs exhibit certain characteristics regarding DL MU-MIMO gain as a function of the number of DL MU-MIMO clients associated to the AP. Accordingly, APs can be configured to operate in accordance with an algorithm that checks the number of DL MU-MIMO capable clients are associated to an AP, and dynamically switch between single- and dual-radio modes of operation to take advantage of those DL MU-MIMO gains.

Abstract: A method including identifying that a client device is physically presented within a coverage area corresponding to a network is provided. The client device is associated with a user having a user credential to log in to the network, and the method includes determining that the client device has not requested to log in to the network using the user credential, and generating an alert to an administrator of the network responsive to both (1) that the client device is physically presented within the coverage area and (2) that the client device has not requested to log in to the network.

Abstract: The full efficiency gains of the Target Wake Time (TWT) mechanism specified in the 802.11ax standard may not be realized when stations associated to an access point (AP) are spread across multiple Base Station Service Identifiers (BSSIDs). In such a scenario, TWT as conventionally utilized/specified in the 802.11ax standard, cannot properly coordinate sleep/wake schedules for stations due to associating to different BSSIDs. Accordingly, various embodiments are directed to grouping stations associated to multiple BSSIDs of an AP to allow for the synchronization (or staggering) of TWT, and facilitate multi-user transmissions, both in the uplink and downlink directions.

Abstract: Embodiments are directed to automatic location of access points in a network. An embodiment of one or more non-transitory computer-readable storage mediums includes instructions for transmitting a request from a computing device to multiple access points in a network to determine a distance between each pair of access points of the multiple access points; receiving at the computing device the determined distances between each pair of access points; generating a proximity matrix containing the determined distances between each pair of access points; solving the proximity matrix to automatically generate a set of locations for the multiple access points; and orienting the generated set of locations for the multiple access points based on known locations of one or more anchor points in a subset of the access points.

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: Examples described herein mitigate adjacent channel interference for dual radios of a network device. Examples described herein may associate, by a network device, a first client device with a first radio of the network device, associate, by the network device, a second client device with a second radio of the network device, determine that the first and second client devices are within a steering threshold, and based on the determination that the first and second client devices are within the steering threshold, steer, by the network device, the second client device from the second radio to the first radio. Examples described herein may communicate, using the first radio of the network device, with the first and second client devices.

Abstract: Examples described herein provide single and dual radio modes by a network device. Examples may include configuring a network device to communicate with a plurality of client devices using one of a single radio mode and a dual radio mode. Examples may include, based on a relation between a first amount of traffic received by the network device from a first subset of the client devices and a second amount of traffic received by the network device from a second subset of the client devices, reconfiguring the network device to communicate with the plurality of client devices using the other one of the single radio mode and the dual radio mode. Examples may include communicating, by the network device, with the plurality of client devices using the other one of the single radio mode and the dual radio mode.

Abstract: Methods for assigning effective isotopic radiated power to an access point in a wireless network are provided. In one aspect, a method includes determining weights for neighboring access points in a wireless network based on channel frequency and basic service set color assignments. For a particular access point, a first path loss based on the determined weights and a second path loss based on the neighboring access points are calculated. First and second effective isotopic radiated power values are calculated based on the respective first and second path losses. The effective isotopic radiated power of the particular access point is adjusted based on the lower of the first and second calculated effective isotopic radiated power values. Systems and machine-readable media are also provided.
