Abstract: An arrangement of three radios maybe provided. The three radios define first and second outer data links and a middle data link. Access to the arrangement of three radios can be biased to the middle data link in one direction upon a data transmission through the first and second outer data links being dominate in an opposite direction. Data transmission with enhanced multi-link single radio (eMLSR) client devices can be prioritized lower than data transmission with simultaneous transmit and receive radio (STR) client devices and non-simultaneous transmit and receive radio (NSTR) client devices. A radio can be configured for data transmission with a client device. The range of the radio is limited when the data traffic through the radio exceeds a determined number of bytes of data in a determined amount of time.

Abstract: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

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: Coordinated Frequency Division Multiplexing (FDM) Transmission Opportunity (TXOP) sharing may be provided by determining that at least two Access Points (APs) of a wireless network support coordinated FDM TXOP sharing. In response to the determination that the at least two APs support coordinated FDM TXOP sharing, at least one of: a first bias is applied to a channel assignment algorithm to promote an assignment of overlapping channels of the at least two APs, and a second bias is applied to the channel assignment algorithm to promote an assignment of adjacent channels of the at least two APs. Next, channels are assigned to the at least two APs based on an output of the channel assignment algorithm.

Abstract: Systems, methods, and computer-readable media may determine location-related data for a plurality of access points located in an area in communication with a network by determining that a plurality of access points in a network are associated with a same geographical area including identifying, from among the plurality of access points, a first access point associated with the geographical area, determining 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 based at least in part on a determination that the second access point has at least a threshold number of the neighbor access points, and 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.

Abstract: In one embodiment, a method comprises first causing, by a controller device, wireless access points (APs) to allocate first non-interfering wireless channels for a prescribed reliable data service for wireless client devices in a WLAN; second causing the wireless APs to allocate a second shared channel having a bandwidth that is greater than the corresponding bandwidth of any of the first non-interfering wireless channels; allocating for each wireless client device a corresponding location service interval on the second shared channel for transmission of at least a corresponding identifiable wireless data unit for locating the corresponding wireless client device between two or more of the wireless APs; and determining a location of at least one of the wireless client devices based on reception of at least the corresponding wireless data unit between the one wireless client device and the two or more wireless APs during the corresponding location service interval.

Abstract: Networked sleep mode management is provided by measuring network conditions for a first Access Point (AP) serving a plurality of Client Devices (CDs) configured to operate in one of a sleep mode and an active mode; in response to detecting, based on the measured network conditions, an amount of network usage devoted to transitioning members of the plurality of CDs from the sleep mode to the active mode satisfies a threshold: identifying a first subset of CDs from the plurality of CDs that are deprioritized for access to the sleep mode; receiving a sleep request from a given CD that is a member of the first subset of CDs; and denying the sleep request to force the given CD to maintain the active mode for at least a predefined amount of time.

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: Techniques for dynamic RF site configuration are provided. Historical association data is collected from a plurality of access points in a physical environment, and a machine learning model is trained to predict future association events, based on the historical association data. Current association data is then collected from the plurality of access points, and at least one predicted association event is generated by processing the current association data using the trained machine learning model. The plurality of access points is allocated to a plurality of radio frequency (RF) sites based on the at least one predicted association event. Finally, at least one of the plurality of RF sites is configured based on the predicted association event.
