Abstract
Systems and methods are presented for sharing the ultra-wide band (“UWB”) spectrum. The systems and methods can include allocating a designated time slice for UWB position determination signals on a primary basis to ensure that the UWB transmissions would be free of interference. The systems and methods can also include synchronizing a plurality of UWB transceivers and emitting synchronized pulses, during the designated time slice.
Claims10
A method of transmitting synchronized ultra-wideband (UWB) position determination signals, comprising:
- a first stage in which course synchronization is accomplished at a master UWB transmitter site;
- and
- a second high resolution synchronization stage wherein one nanosecond pulses are used from the master site out to synchronize one or more UWB slave sites;
- wherein the one or more slave sites each are provided with the co-ordinates of the master site and all other slave sites, and wherein upon receiving the pulses from either the master or another slave site, each can calculate when the pulses were sent by their originating site.
