Abstract: The disclosed technology relates to a process of evaluating any number of different identity providers (IDPs) and their respective set of credentials that are used to authenticate corresponding users to assist with the onboarding of the different IDPs in connection with Wi-Fi identity federations. In particular, the process allows a person's electronic identity and attributes (stored across one or more IDPs) to be determined once using a standard. Once trust has been established for the user, that trust can then be utilized across a number of different systems (e.g., Single-sign on). The same trust determination can be used without the need for the authenticity of the user identity to be re-evaluated with each new access request.

Abstract: Disclosed are systems, apparatuses, methods, computer readable medium, and circuits for transmitting, from an access point (AP), a multi-link device (MLD) grouping to a station device (STA); transmitting, from the AP, a policy to accept energy efficiency instructions that includes multi-link operation (MLO) in an energy conservation mode; transmitting, from the AP, instructions to reduce battery consumption by the station by limiting MLO operations and activating a single radio of a plurality of radios on the STA, wherein a remainder of the plurality of radios are inactive and powered off; determining, at the AP, that activity from the STA is increasing; and transmitting a wake-up message to one or more of the inactive radios on the STA.

Abstract: A system and method are provided for generating a pairwise transient key security association (PTKSA) by: providing a first media access control (MAC) address that is shared by multiple access points (APs), the first MAC address corresponding to an infrastructure comprising the multiple APs, and each AP of the multiple APs having a respective AP MAC address; providing a second MAC address to a station (STA); and establishing a secure link between the STA and the infrastructure using the first MAC address and the second MAC address to derive a pairwise transit key (PTK) for the secure link, wherein the secure link is between the STA and the multiple APs.

Abstract: Parallel Redundancy Protocol (PRP) using non-overlapping Resource Unit (RU) groupings may be provided. A first computing device may associate to a first Access Point (AP) at a virtual Media Access Control (MAC) address. Next, the first computing device may associate to a second AP at the virtual MAC address. Then data from a data frame may be replicated to a first one or more RUs in a channel. The first one or more RUs may be assigned to the first AP. Data from the data frame may then be replicated to a second one or more RUs in the channel. The second one or more RUs may be assigned to the second AP and may not overlap the first one or more RUs.

Abstract: In one embodiment, a method comprises: classifying, by a controller device, a first access point device in a WLAN as a leader access point for a wireless client device, and at least a second access point device as a follower access point; and allocating, to the leader access point, a shortened medium access control layer timer (“timer”) that is shorter than a prescribed timer used by the follower access point, the shortened timer causing the leader access point to respond to reception of a wireless data packet from the wireless client device by transmitting an acknowledgment to the wireless client device upon expiration of the shortened timer; the prescribed timer causing the follower access point to defer to the leader access point based on the follower access point waiting for at least expiration of the prescribed timer before selectively transmitting a corresponding acknowledgment in response to receiving the wireless data packet.

Abstract: This technology allows time synchronization in wireless networks with mobile stations. A wireless network controller transmits instructions to access points (“APs”) within the wireless network to monitor transmissions for time synchronization. One or more second APs observe fine time measurement (“FTM”) exchanges between a first AP and a mobile station. A particular second AP determines whether to perform a time synchronization with the first AP based on the detection of the FTM exchange or a determination that the station is moving toward the second AP. For time synchronization, the second AP determines the time that the first AP transmitted the FTM exchange and the time of transmission from the first AP to the second AP. The second AP synchronizes a second AP clock to the summation of the time of the transmission of the FTM exchange and the time of transmission from the first AP to the second AP.

Abstract: Bi-directional gates for scheduling may be provided. Quality of Service (QoS) requirements for communication between an Access Point (AP) and a plurality of client devices may be received. Then schedules may be determined based on the QoS requirements. Next, an Access Point (AP) may be configured to enable the schedules. Configuring the AP may comprise defining traffic queue assignments for a plurality of traffic class queues on the AP to enable the schedules and defining gate control list entries for a respective plurality of bi-directional gates associated with the plurality of traffic class queues to enable the schedules.

Abstract: A method performed by a system which manages station transition from a Wi-Fi access point includes sending, based on the station roaming to an edge-of-domain access point, a request to neighboring access points to the edge-of-domain access point for neighbor reports. The method includes receiving a cellular signal value from the station, comparing a first signal grade associated with the edge-of-domain access point to a second signal grade associated with the cellular signal value to yield a comparison and generating a link usability rating associated with a link between the station and the edge-of-domain access point. Based at least in part on the comparison and the link usability rating, the method includes transmitting a message to the station suggesting that the station roam from the edge-of-domain access point to a cellular network. An edge of the domain can also be dynamic and vary based on station characteristics.

Abstract: This disclosure describes techniques for selecting network protocols using heatmaps. For instance, a system may receive radio frequency information from one or more sources located within an environment. The system may then generate heatmaps using the radio frequency information, where the heatmaps represent characteristics associated with different network protocols. The characteristics may include signal strengths, throughputs, data packet drop rates, data packet retry rates, and/or the like for various locations within the environment. A user device may then receive the heatmaps from the system. Using a location of the user device and the heatmaps, the user device may determine to communicate using a network protocol from the different network protocols. The user device may then establish a connection using the network protocol.
