Abstract: A Fifth Generation (5G) and Wi-Fi Multi-Access Point Coordination (MAPc) function may be provided. A MAPc processor may determine a first traffic flow and a second traffic flow for a User Equipment (UE) and a property of the first traffic flow and of the second traffic flow. The MAPc processor may schedule restricted Target Wake Time (rTWT) service intervals on a Wi-Fi AP for the first traffic flow, and the MAPc processor may schedule rTWT service intervals on a 5G AP for the second traffic flow. The rTWT service intervals on the Wi-Fi AP may be at different times than the rTWT service intervals on the 5G AP.

Abstract: A reverse time synchronization may be performed between a sending device and a receiving device. Then a Time Error (TE) between the sending device and the receiving device may be determined based on the reverse time synchronization. A gate time on the receiving device may be scheduled based on the determined TE.

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: 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: Preserving transmission properties of real-time scenes in an environment when an increasing number of users join a session may be provided. A plurality of metrics associated with transmission of scenes having a Coarse Grain (CG) layer and a Fine Grain (FG) layer may be determined. Then a current client, based on a first one of a plurality of metrics, may be revoked. One of the following may then be performed: blocking a new client based on a second one of a plurality of metrics; and allowing the new client based on the second one of a plurality of metrics.

Abstract: The present technology allows coordination of channels of private wireless networks utilizing shared licensed and unlicensed spectrum. Wireless network operators in an enterprise location register to participate in a consortium and register licensed, shared, and unlicensed spectrum resources to be shared with other members of the consortium. The wireless network operators request an allocation of spectrum resources from the consortium. The consortium generates a radio resource management (“RRM”) plan for shared use of the licensed, shared, and unlicensed spectrum resources. The consortium combines the allocated licensed, shared, and unlicensed spectrum from each of the wireless network operators to meet the target RRM plan. The consortium monitors spectrum utilization to dynamically update the RRM. The consortium monitors spectrum utilization in real time to determine how closely the RRM plan matches the resources allocated to each wireless network operator.

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: Roaming Consortium Identifier (RCOI)-based handling of identity requirements may be provided. First, an access device may advertise an identifier. The identifier may identify a roaming federation and an identity type used by a service provider in order to provide service by the access device. Next, a request to associate with the access device may be received from a user device. The request may be compliant with the identity type advertised in the identifier. The user device may then be associated with the access device in response to receiving the request.

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.
