Abstract: Example method includes: receiving, by a network device, a plurality of notifications from a plurality of access points in a wireless local area network (WLAN), each notification indicating detection of a particular radar event on a particular wireless communication channel; identifying, by the network device, at least one access point operating on the particular wireless communication channel beside the plurality of access points that fails to detect the particular radar event; and transmitting, by the network device, instructions to the at least one access point, wherein the instructions cause the at least one access point to switch to operate on a different wireless communication channel.

Abstract: Examples relate to access point signal estimation. In one example, a computing device may: receive a first pathloss value in a first frequency, the first pathloss value indicating a difference in transmit power of a particular access point and a received signal strength observed by a first access point; receive a second pathloss value in the first frequency, the second pathloss value indicating a difference in transmit power of the particular access point and a received signal strength observed by a second access point; receive a third pathloss value in a second frequency, the third pathloss value indicating a difference in transmit power of the particular access point and a received signal strength observed by the second access point in the second frequency; and generate, using the first, second, and third pathloss values, an estimated pathloss between the first access point and the particular access point in the second frequency.

Abstract: Systems and methods are provided for specifying a link recommendation. Such a link recommendation can recommend a particular multi-link operation (MLO) link between an access point (AP) multi-link device (AP MLD) and a non-AP MLD, such as a client device or station for use when exchanging data frames. Conventional usage of MLO can result in non-AP MLDs attempting to associate to a particular AP MLD over the same link, which can result in overloading of that link. This is because the implementation of MLO elevates the context of AP-client device/station association to a higher level, i.e., the device/MLD level, and the link on which data frames are sent or received between an AP MLD and a non-AP MLD s no longer a consideration/relevant. However, the transmission of link recommendations indicating links to use (or to avoid), avoids or lessens the risk that multiple non-AP MLDs attempting to associate to an AP MLD will overload or overuse the same link.

Abstract: Systems and methods are provided for defining basic service set (BSS) colors and spatial reuse groups (SRGs) for multiple basic service set identifier (MBSSID) sets. The systems and methods can set a first BSS color for a first MBSSID set and a second BSS color for a second MBSSID set, the MBSSID sets pertaining to a first access point. For a second access point, the system can set a third BSS color for a third MBSSID set and a fourth BSS color for a fourth MBSSID set. A SRG can be defined for the first MBSSID set, wherein the first spatial reuse group advertises the first BSS color and any BSS colors associated with the second access point.

Abstract: An example network information aggregator is disclosed. The network information aggregator includes a network interface, a memory, and processing circuitry. The processing circuitry is to receive a machine learning model trained using initialization data from a model creation device. The processing circuitry is also to generate a device steering rule to steer a client device from a first radio to a second radio using the machine learning model. The processing circuitry is also to send a steer command to the first radio.

Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for increasing the reliability of voice traffic and Transmission Control Protocol (TCP) Acknowledgement (ACK) messaging. The result is improved quality of voice calls, and enhanced network capacity. When the length of a data section of a packet suggests that subsequent packets are associated with voice traffic or TCP ACKs, such packets are not transmitted when another transmission(s) is occurring under spatial reuse. When a determination is made that the length of a data section of the packet suggests non-voice traffic or TCP ACKs, they can be transmitted simultaneously with other transmissions occurring under spatial reuse.

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.

Abstract: An access point configured to manage client devices connected to the access point. The access point initiates an operational change. The access point generates an announcement to be included in a network frame based on the operational change. The announcement includes at least a list of neighboring access points with which the client devices can connect to and a first time period by which the client devices must connect to at least one neighboring access point included in the list of neighboring access points. The access point broadcasts the network frame to the client devices. Upon expiration of the first time period, the access point disassociates client devices that remain connected to the access point.

Abstract: Systems and methods are provided for leveraging uplink (U)L scheduling information obtained by way of Quality of Service (QoS) Null/QoS Data frames and Media Access Control (MAC) headers transmitted by any station (STA). This UL scheduling information can be read by any access point (AP) in an extended service set (ESS), and used to improve network performance. For example, an AP may use such UL scheduling information (from STAs associated to co-channel APs in the same ESS) to minimize the latency for UL latency-sensitive traffic in that ESS. Additionally, an AP may use such UL scheduling information to minimize contention amongst STAs connected to different APs on the same channel in the same ESS, thereby improving system capacity.
