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: 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: In one embodiment, a method includes receiving a request from an access point to transmit to a TSN data payload to a wireless TSN station, identifying resource units (RUs) in a downlink channel, each RU comprising a set of RU tones, identifying access category (AC) queues, multiplexing the RUs and AC queues to generate RU and AC queue pairs, generating timing boundaries of the pairs, wherein each timing boundary represents a combination of an average airtime of each RU and an average wait time of each AC queue for transmitting a size of the TSN data payload, iteratively validating the timing boundaries with a TSN lookahead time, and determining a first RU tone from a first RU associated with a first timing boundary less than the TSN lookahead time to transmit the TSN data payload in a first AC queue to the wireless TSN station.

Abstract: Disclosed are systems, apparatuses, methods, computer readable medium, and circuits for tracking location by a positioning service. According to at least one example, a method includes: receiving distance measurements from a first anchor device; determining a trust value associated with a path between the first anchor device and a second anchor device based on the distance measurements, wherein the trust value corresponds to whether the path is obstructed; determining a first measurement interval to measure a distance from the first anchor device to the second anchor device based on a single-sided measurement and a second measurement interval to measure the distance from the first anchor device to the second anchor device based on a double-sided measurement; and sending an anchor configuration to the first anchor device including the first measurement interval for the single-sided measurement and the second measurement interval for the double-sided measurement of the second anchor device.

Abstract: A system and a method to delegate out-of-band (OOB) management of a shared ultra-wideband (UWB) clock. The system may comprise a tagged device with a UWB tag and multiple anchors. The tagged device may be configured to establish at least one OOB communication link with at least one anchor, transmit UWB compatibility information to multiple anchors, establish a UWB communication links with the anchors, and exchange OOB synchronization parameters and UWB synchronization parameters with the anchors. Further, the tagged device may be configured to define new instructions for ranging round operations based at least in part upon the OOB synchronization parameters and the UWB synchronization parameters, update existing instructions with the new instructions in the ranging round operations, and perform the ranging round in accordance with the updated instructions.

Abstract: A method is provided that is performed in a wireless network to detect a rogue wireless device. The method comprises detecting a suspect wireless device in the wireless network based on messages transmitted by the suspect wireless device using a first Media Access Control (MAC) address that is also used by a valid wireless device in the wireless network. When a suspect wireless device is detected, the method next includes sending to the valid wireless device in the wireless network a request configured to cause the valid wireless device to change its MAC address. After the valid wireless device has changed its MAC address, the method involves observing messages transmitted by the suspect wireless device in the wireless network. The method then includes determining that the suspect wireless device is a rogue device when the suspect wireless device continues to transmit messages using the first MAC address.

Abstract: Backscatter Device (BKD) placement and placement calibration may be provided. A plurality of ambient energy sources of a Three-Dimensional (3D) space may be caused to transmit charging frames for Backscatter Devices (BKDs). Each of the charging frames may include a payload having a Media Access Control (MAC) address of transmitting ambient energy source. An amount of ambient energy received from the charging frames of the plurality of ambient energy sources and each contributing source may be received from survey devices placed at positions along a sub-space of the 3D space. The amount of ambient energy available from each contributing source at each positions along the sub-space per predetermined time period may be predicted based on the amount of ambient energy received from the plurality of ambient energy sources.
