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.

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: Aspects herein generally relate to a system and/or a method for enforcing synchronization of WiFi users interacting with a common hierarchical multi-element VR/AR scene. The aspects can use Orthogonal Frequency Division Multiple Access (OFDMA) and trigger frames to synchronize parallel updates to different scene elements. Deep Packet Inspection (DPI) can be used to analyze standard VR/AR streaming formats to identify those VR scene elements that are to be synchronized. The result is a more immersive AR/VR experience for the users, who receive the same scene elements at the same time.

Abstract: In one embodiment, a method for providing access to wireless networks may include receiving, by a wireless network access provider from a user device, a request to access a wireless network. The method may include obtaining data representing a policy applicable to the access request, sending the access request, augmented with the policy, to an identity provider associated with the user and having no pre-existing relationship with the access provider, and receiving, from the identity provider, an access request response indicating whether or not the policy is met. The method may include communicating, to the wireless device, an indication that the access request has been accepted, if the policy is met, or an indication that the access request has been rejected, if the policy is not met. The access provider and identity provider may be members of an identity and access federation that communicate over a dynamically established secure connection.
