Abstract: Systems and methods are configured to receive a first request to schedule a Time To Wake (TWT) service period (SP) for a first station. The first request can be based on individual TWT protocol. That the TWT SP satisfies a threshold level of similarity with an existing TWT SP maintained for a group of at least one station scheduled to communicate over the existing TWT SP can be determined. The group can include a second station. The first station can be assigned to the group. A first packet can be transmitted to the first station and a second packet can be transmitted to the second station over the existing TWT SP.

Abstract: Systems and methods for spatial reuse in a deployed wireless area network (WLAN) include identifying a plurality of competing APs of an external wireless network operating on a same channel as a deployed AP of a deployed wireless network; examining the received signal strength indicator (RSSI) of the identified plurality of competing APs of the external wireless network; filtering out selected one or more of the identified plurality of competing APs of the external wireless network based on their respective RSSIs to arrive at a filtered set of competing APs; and augmenting a spatial reuse group (SRG) of the deployed AP to include the APs in the filtered set of competing APs in the SRG.

Abstract: Systems and methods are disclosed for generating a client device fingerprint model and identifying client devices using the model. Identifying client devices includes monitoring traffic transmitted over a wireless network to an unknown first client device, the traffic using at least one value of at least one wireless network operational parameter; determining, for each at least one value of the at least one wireless network operational parameter, a respective probability of successful packet reception at the first client device; comparing each probability to a data model representing probabilities of successful packet reception at each of a plurality of known second client devices for each of a plurality of values of the wireless network operational parameter; and associating at least one of the labels of the second client devices with the first client device based on the compare.

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.

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.
