Abstract: Devices, systems, methods, and processes for hybrid line-of-sight (LOS)/non-line of sight (NLOS) detection are described herein. To facilitate co-existence and co-operation of a fixed network and a wireless network sharing a same frequency band without interference, a device in the wireless network can be configured to perform automatic frequency coordination (AFC). The device can accurately determine a geolocation of the device by utilizing global navigation satellite system (GNSS) data and light detection and ranging (LiDAR) data. The device can also determine whether the fixed station is in the LOS by utilizing the GNSS data and the LiDAR data. The device can further correct the geolocation and improve an accuracy of the LOS/NLOS detection by using both: the GNSS data and the LiDAR data simultaneously. The device can further control an output power when the fixed station is in the LOS, thereby avoiding the interference.

Abstract: Devices and methods for floor-level allocation of network devices, for example, access points, are provided. A controller, coupled to multiple switches disposed across one or more floors in a space, receives discovery data and signal data. The discovery data, for example, connectivity discovery protocol data, indicates an association of the switches and multiple access points connected thereto and deployed across the floor(s). The signal data, for example, received signal strength indicator data, is associated with the set of access points. The controller classifies the access points into a set of clusters based on the discovery data and the signal data. The controller determines a sequence of the floors based on the clusters and allocates a floor-level identifier to the access points based on the sequence. The devices and methods optimize indoor localization, for example, in environments where environmental data such as air pressure data may be unreliable or unavailable.

Abstract: Ultra Wideband (UWB) radar integrated Fine Timing Measurement (FTM) based indoor locationing may be provided. First, a computing device may detect that Non Line of Sight (NLOS) conditions exist based on a spatial layout derived using the UWB radar. Next, the computing device may determine a delay error, in response detecting that the NLOS conditions exist, based on the spatial layout. Then the computing device may adjust FTM times using the delay error.

Abstract: In one aspect, a method is disclosed. The method includes transmitting, from a first anchor in an Ultra-Wide Band (UWB) network, a poll message to a second anchor associated with the UWB network, wherein the poll message includes a first indication of radar usage by the first anchor. The method includes receiving, from the second anchor at the first anchor, a response message in response to the poll message. The response message includes a second indication of radar usage by the second anchor. The method includes determining, by the first anchor, a format of at least one ranging frame to enable dual radar and downlink time difference of arrival (DL-TDoA) ranging by one or more of the first anchor and the second anchor based on the poll message and the response message.

Abstract: Techniques for optimizing the coexistence of UWB and Wi-Fi transmissions are provided. A synchronization schedule is received from an Ultra-wideband (UWB) network device. The synchronization schedule is analyzed to determine one or more timings for one or more UWB transmissions. A schedule for one or more Wireless Local Area Network (WLAN) transmissions is adjusted to avoid interference with the one or more UWB transmissions. The adjusted schedule for the one or more WLAN transmissions is communicated to a WLAN device.

Abstract: Techniques for improved localization and ranging with reduced resource consumption are provided. At a first time, first movement information for a client device is determined. Based on the first movement information, a first set of localization parameters is selected. One or more localization techniques are performed in accordance with the first set of localization parameters. At a second time, second movement information for the client device is determined. Based on the second movement information, a second set of localization parameters is selected. One or more localization techniques are performed in accordance with the second set of localization parameters.

Abstract: Techniques for optimizing the coexistence of UWB and Wi-Fi transmissions are provided. One or more frequency bands causing spectral leakage that impacts an ultra-wideband (UWB) network device are identified. A synchronization schedule is received from the UWB network device. The synchronization schedule is analyzed to determine one or more timings for one or more UWB transmissions. One or more Wireless Local Area Network (WLAN) transmissions are punctured to avoid interference with the one or more UWB transmissions.

Abstract: Devices and methods for locationing with Bluetooth-assisted Ultra-Wide Band (UWB) ranging are provided. To support UWB ranging based on a Bluetooth Low Energy (BLE) out-of-band mechanism, establishing a BLE connection for each of a plurality of network devices is not feasible. To allow client devices to autonomously determine their location, virtual BLE addressing with shared keys is implemented. A client device configures first and second UWB ranging exchanges associated with first and second network device sets, respectively, based on bonding data associated with virtual Bluetooth addresses. The client device obtains first and second UWB ranging data and transmits the first or second UWB ranging data to a cloud for locationing. Based on the reuse of the virtual Bluetooth addresses across the first and second network devices sets, the client device perceives the same known set of network devices for connection rather than the plurality of network devices.
