Abstract: A method for calibrating a magnetometer of a device is provided. The method includes collecting, with a portable calibration device having a magnetometer, magnetic field measurements in a spatial region about a mounting location where the device is to be installed for operation, estimating magnetometer compensation parameters to correct for magnetic field distortion at the mounting location based on the magnetic field measurements collected by the portable calibration device, and configuring the device installed at the mounting location based on the magnetometer compensation parameters.

Abstract: The presently claimed disclosure is directed to methods that may be implemented at a computer. Methods and systems consistent with the present disclosure may include extending protocols associated with authenticating client (i.e. supplicant) devices and with authorizing those supplicant devices to access a wireless network. These methods may include sending data relating to the failure of an authentication and/or an authorization process to a supplicant device attempting to access a wireless network. Methods discussed within may include securely sending failure codes or reasons to a supplicant device that identify why an authentication or authorization process failed. These methods may include sending messages between a supplicant device, an authenticator device, and an authentication and authorization server. After a first failure, the supplicant device may be able to access the wireless network after a reason or code of that failure has been reported to the supplicant device.

Abstract: Preemption in wireless may be provided. Access Category (AC) parameters may be received for a preemption AC within a plurality of ACs. The preemption AC parameters may comprise a Contention Window maximum (CWmax) comprising a first predetermined value and a preemption Arbitrary Interframe Space Number (AIFSN) of less than or equal to a second predetermined value. AC parameters for others of the plurality of ACs may be received wherein a non-preemption AIFSN associated with any of the others of the plurality of ACs is greater than a sum of the first predetermined value the second predetermined value. Preemption for traffic in the preemption AC may be allowed.

Abstract: In one embodiment, a method comprises first causing, by a controller device, wireless access points (APs) to allocate first non-interfering wireless channels for a prescribed reliable data service for wireless client devices in a WLAN; second causing the wireless APs to allocate a second shared channel having a bandwidth that is greater than the corresponding bandwidth of any of the first non-interfering wireless channels; allocating for each wireless client device a corresponding location service interval on the second shared channel for transmission of at least a corresponding identifiable wireless data unit for locating the corresponding wireless client device between two or more of the wireless APs; and determining a location of at least one of the wireless client devices based on reception of at least the corresponding wireless data unit between the one wireless client device and the two or more wireless APs during the corresponding location service interval.

Abstract: Cluster formation for networks for Ultra-Wideband (UWB) Time-Difference-of-Arrival (TDoA) networks may be provided. A plurality of anchors may be set to a primary setting. Synchronization messages may then be broadcast by the plurality of anchors. Then the plurality of anchors may send responses to the synchronization messages. A room consensus may be performed to determine probabilities of obstacles between the plurality of anchors. The plurality of anchors may then send proposals of one or more clusters based on the room consensus. One or more clusters may be formed by the plurality of anchors based on the proposals.

Abstract: A method is provided that is performed for a wireless network that includes one or more wireless client devices that may rotate their media access control (MAC) address used for wireless communication with one or more wireless access point devices in the wireless network. The method includes determining an impact of MAC address rotation by the one or more wireless client devices on operational resources of one or more networking devices or networking processes in a network infrastructure associated with the wireless network. The method further includes scheduling MAC address rotation by the one or more wireless client devices according to the impact on operational resources of the one or more networking devices or networking processes in the network infrastructure.

Abstract: Disclosed are methods, systems, and non-transitory computer-readable media for using a sponsor as a proxy for multi-factor authentication of a first user account for a first user when a primary multi-factor authentication mechanism is unavailable to the first user account, comprising registering the sponsor in a multi-factor authentication chain of trust associated with the first user account; requesting verification of an identity of the first user from the sponsor; receiving, from the sponsor, a verification of the identity of the first user; and granting access to a service to the first user account.

Abstract: Presented herein are infrastructure triggering techniques for secure Ultra-Wideband (UWB) ranging. In one example, a method may include providing UWB ranging parameters to a mobile device via a first radio communication, wherein the first radio communication is a non-UWB radio communication; and triggering the mobile device to perform UWB ranging with a UWB anchor, wherein the triggering is performed using a second radio communication. In another example, a method may include, obtaining, by a mobile device, UWB ranging parameters for a geographic area; obtaining a UWB ranging instruction for the geographic area; and performing UWB ranging with a target UWB anchor based on the UWB ranging parameters and the UWB ranging instruction.

Abstract: Embodiments identify a station that rotates an over the air station address. As address rotation was not originally designed into wireless networks, the rotation can introduce communication challenges for the station. The embodiments derive that traffic referencing two different over the air station addresses are associated with a single common station. This is accomplished by determining a similarity between properties of two sets of traffic. A first set of traffic references the first over the air station address and a second set of traffic references the second over the air station address. If the properties common across the two sets of traffic indicate sufficient similarity, the embodiments determine that both sets of traffic are associated with a single device. Network configuration of the device is then adjusted based on the determination.
