Abstract: The invention discloses an ultra-wideband (UWB) positioning system, UWB base stations (BSs), UWB tags and the operation methods thereof. Because the present invention uses a server aware of the positions of all BSs to determine the BSs that performs distance measurement, and the server assigns different time slots to each BS that performs distance measurement, the present invention can avoid collisions between the BSs in the process of distance measurement. Furthermore, because the tag can select a specific time slot to access the UWB positioning system by monitoring the UWB signals in the air, the present invention can reduce collisions between the tags. By carefully planning the system frames and subframes of the time division multiplexing system, and sophisticatedly arranging the operation timings of the BSs and the tags, the present invention provides practical and stable UWB positioning system, BSs, and tags.

Abstract: An internet of things is disclosed, comprising plural SDR receivers and possibly a centralised system, where one or more of the receivers may be mobile. The internet of things thus allows for a very large proportion of RF signals present within a city, for example, to be monitored and analysed for the purpose of identifying, tracking and/or preventing criminal behaviour. The receivers may be equipped with secure SDRs for increased security and privacy and the system preferably includes artificial intelligence using machine learning technology, for increased adaptability among others. The system is flexible due to the programmability of the SDRs.

Abstract: A method is provided for configuring a tracking system which estimates a location within a space by comparison of measurements of RF signals, made at the location, with a radio fingerprint map of the space. Estimated locations are correlated with synchronised detections of presence of a user (30) by sensors of a lighting system. RF signal measurements made by a user at a given time may thereby be associated with a user (30) detected at the same time in one or more respective sensing areas of lighting system sensors. The user (30) making RF signal measurements at a determined location may thereby be associated with a user (30) detected by the lighting system sensors at the same time. The association may be used to configure the radio fingerprint map. The location of the detected user (30) as determined by the tracking system may be provided to the lighting system.

The device transmits a UL cloned CSW signal based on the cloned chirp sensing waveform. The transmit point receives the UL cloned CSW signal and processes the UL cloned CSW signal to estimate a pose for the device and associate the estimated pose with the identity of the device.

Abstract: Systems and methods are provided for performing a live upgrade process of one or more devices (e.g., access points (APs), etc.) in a large scale network environment. For example, the system can use neighbor path loss data between the APs. The neighbor path loss data may identify the signal strength between two points as an indication of the ability to transmit power and receive power from the individual APs. When the ability to transmit and receive power is present in one AP is unavailable the user device may connect to a second AP to avoid losing connectivity. This neighbor path loss data may be utilized to perform a live upgrade process of APs in parallel at multiple locations of the user site.

Abstract: Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A control device can monitor UWB ranging between a mobile device and a primary anchor. In response to determining that a signal strength between the mobile device and the primary anchor is below a threshold, the control device can identify anchors for which the mobile device has had a signal strength above the threshold during a period of time, and select one of the anchors as a new primary anchor for the mobile device. For example, the control device can select the new primary anchor based on a relative collision tolerance mapping for the new primary anchor and at least one other anchor within a UWB range of the new primary anchor. The control device can send a command causing UWB ranging to be performed between the mobile device and the new primary anchor.
