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.
Claims10
A system for distribution of time synchronization information to ultra-wide-band (UWB) devices, the system comprising:
- a plurality of anchors, wherein each anchor comprises at least one anchor processor, an anchor UWB radio, and an anchor timing system, wherein each anchor performs UWB ranging on a subset of a plurality of tags, each securable to an object for tracking, wherein each tag comprises at least one tag processor, a tag UWB radio, and a tag timing system, wherein the tag timing systems and the anchor timing systems are time synchronized;
- and
- a site master configured for transmitting a first time-synchronization message to a first anchor in a first UWB coverage island and a second anchor in a second UWB coverage island, wherein the first anchor is configured for distributing time synchronization information to a first plurality of anchors within the first UWB coverage island by one or more first UWB transmissions, and wherein the second anchor is configured for distributing time synchronization information to a second plurality of anchors within the second UWB coverage island by one or more second UWB transmissions.
A method for distribution of time synchronization information to ultra-wide-band (UWB) devices, the method comprising:
- initializing a UWB local area network (LAN) comprising a plurality of anchors and a plurality of tags, each secured to an object for tracking, wherein each anchor comprises:
- at least one anchor processor, an anchor UWB radio, and an anchor timing system, and wherein each tag comprises:
- at least one tag processor, a tag UWB radio, and a tag timing system, wherein the tag timing systems are synchronized to the anchor timing systems;
- transmitting, from a site master, a first time-synchronization message to a first anchor in a first UWB coverage island and a second anchor in a second UWB coverage island;
- distributing time synchronization information, from the first anchor, to a first plurality of anchors within the first UWB coverage island by one or more first UWB transmissions;
- and
- distributing time synchronization information, from the second anchor, to a second plurality of anchors within the second UWB coverage island by one or more second UWB transmissions.
