Abstract: In embodiments of the present disclosure, a method is provided for managing a mesh point. A request is transmitted from a mesh point to a mesh portal, and the request indicates that Reduced Neighbor Report (RNR) information is required. A beacon with the RNR information is received from the mesh portal. A mesh link is established with a target mesh portal based on the beacon with the RNR information. Therefore, the time cost and the data communication of a scanning procedure of the mesh point may be greatly reduced. Further, communications in the scanning procedure are lowered, such that conflicts in the air may be alleviated.

Abstract: Systems and methods are provided for synchronizing uplink (UL) and downlink (DL) traffic. In particular, frames associated with Quality of Service (QoS}-sensitive traffic flows to be transmitted in a first direction are prioritized commensurate with frames to be transmitted in a second direction, different/opposite to that of the first direction. For example, UL traffic flows can be prioritized based on DL traffic flows, where the traffic flows belong to the same application flow, and vice versa, where DL traffic flows can be prioritized based on UL traffic flows for the same application flow. In this way, end-to-end QoS can be achieved.

Abstract: Systems and methods are provided for transmitting buffer state report poll (BSRP) triggers from a WLAN device with a BSRP frequency that is based on an amount of pending data at the UL buffer of each station associated to the WLAN device. The BSRP frequency can further be based on a priority of the pending data at the UL buffer. The amount of pending data at the UL buffer can be compared to a threshold, the value of which can depend on the priority of the pending data, and the BSRP frequency can be based on the comparison.

Abstract: In one example a computer implemented method comprises receiving, at an access point of a wireless network, a multicast/broadcast frame which identifies one or more stations associated with the access point as a recipient for the multicast/broadcast frame, and in response to a determination that at least one station of the one or more stations identified as a recipient for the multicast/broadcast frame is in an inactive state, determining a beacon slot time for a transmission of the multicast/broadcast frame from the access point, in response to a determination that at least one of the one or more stations in an inactive state will miss the beacon signal, converting the multicast/broadcast frame to a unicast frame, and holding a copy of the unicast frame to be transmitted to the at least one of the one or more stations in an inactive state that will miss the beacon signal.

Abstract: Systems, methods, and computer readable mediums for persistent TWT sessions include establishing, by an access point, a plurality of sessions with a plurality of stations, wherein one or more of the plurality of sessions comprise a target wake time (TWT), determining, by the access point, that a downtime event will occur before a TWT of a particular station of the plurality of stations, in response to the downtime event occurring during the TWT of the particular station, sending, by the access point, information associated with the plurality of sessions to a secondary device, after the downtime event, retrieving, by the access point, the information associated with the plurality of sessions from the secondary device, and reestablishing, by the access point using the information, the plurality of sessions.

Abstract: Example implementations relate to partitioning a radio into chains to scan channels. In some examples, a network device may comprise a processing resource and a memory resource storing machine-readable instructions to partition a default radio of the network device into a service chain and a scan chain in response to a scan request, scan a particular channel with the scan chain to discover devices operating on the particular channel of a network, and combine the service chain and the scan chain into the default radio.

Abstract: Systems and methods are provided for upgrading wireless network devices, such as access points (APs). When a first AP needs an upgrade, a network controller of the first AP may identify and select a neighbor AP. The radio(s) of the neighbor AP can be split into multiple logical radios, at least one of which includes a backup virtual AP (VAP). The backup VAP can support client devices originally supported by the first AP, allowing those client devices to roam to the neighbor AP while the first AP is upgrading, and without needing to re-associate with the neighbor AP. From the client device perspective, it appears as though they are still being supported by the first AP. Upon upgrading the first AP, the client devices can roam back to the first AP (without needing to re-associate with the first AP). No downtime is experienced, and no RF holes are generated.

Abstract: Example method includes: receiving, by an access point in a wireless local area network (WLAN), a plurality of wireless interference signals from an interfering device; deriving, by the access point, a fast Fourier transformation (FFT) pattern from the plurality of wireless interference signals received from the interfering device; transmitting, by the access point, the FFT pattern to a centralized repository that is remote to the access point; receiving, by the access point, a classifier from the centralized repository; and classifying, by the access point, the interfering device into a specific device type using the classifier received from the centralized repository based on the FFT pattern.

Abstract: In one example a computer implemented method comprises estimating, in a processor communicatively coupled to a wireless client of a composite device, a first transmission time for an uplink beacon from a first access point communicatively coupled to the wireless client, scheduling, in the processor, a second transmission time for a beacon from a local access point of the composite device, and defining a scan window during which scan operations for the wireless client of the composite device and the local access point of the composite device are to occur, the scan window offset from the second transmission time by a first time buffer.
