  • Patent number: 11838822
    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.

  • Publication number: 20230388288
    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.

  • Patent number: 11825408
    Abstract: Systems, methods, and computer-readable media for controlling link selection and aggregation across multiple wireless networks based on a location of a mobile device. A location of a mobile device in a physical environment can be identified. At least portions of the physical environment can be in wireless range of a first wireless network and a second wireless network. Whether to access network services through either or both the first wireless network and the second wireless network can be determined based on the location of the mobile device in the physical environment. Further, a first interface at the mobile device to the first wireless network and a second interface at the mobile device to the second wireless network can be selectively toggled according to whether it is determined to access the network services through either or both the first wireless network and the second wireless network based on the location.
