Abstract: Methods, systems, and computer readable media for distribution of time synchronization information to ultra-wide-band (UWB) devices are disclosed. A system includes anchors and tags having synchronized timing systems. The system includes a site master configured for transmitting a first time-synchronization message to at least a first anchor. The first anchor is configured for distributing time synchronization information to at least a second anchor by transmitting a first UWB message during an assigned time slot for the first anchor. The first UWB message includes timing information based on the first time-synchronization message.

Abstract: Methods, systems, and computer readable media for time-slotted ultra-wide-band (UWB) object tracking are disclosed. A system includes anchors and tags having synchronized timing systems. The anchors are configured for performing time-slotted UWB ranging during time windows, one for each tag. During each window, the anchors sequentially transmit UWB transmissions in designated time slots, one for each anchor, as specified by an order of operation. The anchors receive responsive UWB transmissions from the tag assigned to the time window and determine time-of-flight measurements for the responsive UWB transmissions.

Abstract: Methods, systems, and computer readable media for providing and using ultra-wide-band (UWB) local area networks (LANs) are disclosed. A system for locating UWB devices includes UWB local area networks (LANs). Each UWB LAN includes anchors configured for performing UWB ranging and a LAN master anchor surrounded by at least some of the anchors. The LAN master anchor is configured for transmitting a UWB beacon to identify the UWB LAN to one or more candidate tags to join the UWB LAN. The system includes a tag securable to an object for tracking. The tag is configured for receiving a first UWB beacon from a first LAN master of a first UWB LAN; receiving a second UWB beacon from a second LAN master of a second UWB LAN; and determining to associate with the first UWB LAN based on the first UWB beacon and the second UWB beacon.
