Abstract: Various embodiments herein disclose coordinating frequencies for an access point (AR). A corresponding method comprises evaluating a performance profile for the AR, the performance profile comprising a first part related to a first network generated by a first radio of the AR and a second part related to a second network generated by a second radio of the AR. The method also comprises selecting first channels on which the AR generates the first network based on the performance profile and spectral regrowth profiles for transmission power levels of the first radio. The method additionally comprises selecting second channels on which the AR generates the second network based at least in part on the performance profile and the spectral regrowth profiles. Furthermore, the method comprises enabling communications between a first set of devices on the first channels and enabling communications between a second set of devices on the second channels.

Abstract: A method includes performing a first iteration of automated frequency coordination (AFC) using geospatial coordinates of a first access point at a site and a first margin of error to determine a first number of allowed channels for the first access point and performing a second iteration of AFC using the geospatial coordinates of the first access point and a second margin of error to determine a second number of allowed channels for the first access point. The first margin of error is lower than the second margin of error. The method also includes, in response to determining that a difference between the first number and the second number meets a threshold, instructing a second access point at the site to perform AFC using the second margin of error rather than the first margin of error.

Abstract: Techniques herein facilitate a device address rotation management protocol that may be implemented for a wireless local area network (WLAN), which can be used to influence when wireless client devices or stations may rotate their Media Access Control (MAC) addresses, how to perform such rotations, and/or the like. In one example, a method may include providing, by an access point (AP), a first communication indicating that the AP supports a MAC address rotation management protocol; obtaining, by the AP, a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and transmitting, by the AP, a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information.

Abstract: A host clock value may be provided to a client device. An Access Point (AP) may obtain a Timing Synchronization Function (TSF)-based time stamp. Next, the TSF-based time stamp may be placed in an Information Element (IE) that was intended to contain follow up information. The IE may then be transmitted.

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: 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: A Quality of Service (QoS) based wireless coverage map may be provided. First, a station may be identified by an Access Point (AP) in a Wireless Local Area Network (WLAN). Next, a report request may be sent by the AP to the station in response to identifying the station. A report may then be received from the station in response to the report request. The report may comprise information. The information may comprise a location of the station and data indicating a strength of a signal from the AP at the station. A map may be created based on the received report. The map may indicate a hole in the coverage of the WLAN.
