Abstract: Systems and methods herein can analyze a bandwidth restriction in a communication stream of an Access Point (AP). Then, based on the bandwidth restriction, the AP can determine a lower amount of wireless bandwidth to provide to station wireless communicating to the AP. The AP can then modify a bandwidth allocation assigned to the station based on the lower amount of wireless bandwidth.

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: A method is performed at a first multilink device configured to communicate wirelessly with a first radio and a second radio of a second multilink device. The method includes accessing a set of parameters for a known mathematical model that establishes a frequency separation to be imposed between transmission from the first radio and reception at the second radio in order to achieve a predetermined reception performance at the second radio when the transmission and the reception are simultaneous. The method further includes, using the known mathematical model, computing the frequency separation based on the set of parameters.

Abstract: Networked sleep mode management is provided by measuring network conditions for a first Access Point serving a plurality of client devices configured to operate in one of a sleep mode and an active mode; in response to detecting an amount of network usage devoted to transitioning members of the plurality of client devices from the sleep mode to the active mode satisfies a threshold: identifying a first subset of client devices from the plurality of client devices that are in the sleep mode; identifying a given client device from the first subset of client devices to transition to the active mode; and transmitting a tear-down message to the given client device that instructs the given client device to transition from the sleep mode to the active mode.

Abstract: A system may be configured to identify from among a plurality of access points in an area in communication with a network, a first access point associated with the area. In addition the system may also be configured to determine first location-related data for the first access point. Determining second location-related data for a second access point of the plurality of access points, the second access point being interior to the first access point within the network includes exchanging ranging data indicative of a first relative distance between the first access point and the second access point, the ranging data based at least in part on ranging message exchange measurements, and communicating the first location-related data from the first access point to the second access point.

Abstract: Augmenting a neighbor report with uplink Received Signal Strength Indicators (RSSIs) may be provided. First, a conducted transmit power value of a client device may be determined. A plurality of RSSI uplink values respectively corresponding to a plurality of Access Points (APs) may then be determined. Next, a plurality of RSSI downlink values respectively corresponding to the plurality of APs may be determined based on the respective plurality of RSSI uplink values, a respective plurality of conducted transmit power values corresponding to the plurality of APs, and the conducted transmit power value of the client device. A plurality of quality metrics respectively corresponding to the plurality of APs may then be determined based on the determined plurality of RSSI uplink values and the determined plurality of RSSI downlink values. Then, a neighbor report may be optimized based on the plurality of quality metrics.

Abstract: A method for scheduling a random access trigger frame (RA TF) in a wireless LAN includes determining whether a scheduled access (SA) TF is scheduled during a beacon interval (BI) beginning with a next beacon; determining whether one of, a first weighted average of a sum of (i) a number of clients whose respective buffer status reports (BSRs) have been successfully received (NSUCC) and (ii) a number of clients whose respective BSRs collided with one another (NCOL) is greater than a first threshold, or a second weighted average of an active number of UL OFDMA enabled HE users sending SU uplink traffic (NSU) is greater than the first threshold; when either weighted average is greater than the first threshold, allocating a predetermined number of RA RUs along with at least one SA RU in a buffer status report poll (BSRP) TF and scheduling the BSRP TF for transmission.

Abstract: In one embodiment, a technique for automatic classification and enforcement of low-bandwidth 20 MHz-only Internet of Things (IoT) devices is provided. An access point in communication with a plurality of devices may classify one or more client devices of the plurality as low-bandwidth or 20 MHz-only devices. The access point may allocate a subset of resource units (RUs) in a channel (e.g., a 20 MHz-wide channel) to the one or more client devices. The access point may then exchange data with the one or more client devices using the subset of RUs.
