1. A system, comprising:
a first tagged device comprising a first ultra-wideband (UWB) tag communicatively coupled with a first processor, the first processor being configured to:
receive out-of-band (OOB) communication information from a first anchor of a plurality of anchors;
request to establish a first OOB communication link with the first anchor based at least in part upon the OOB communication information;
establish the first OOB communication link with the first anchor;
in response to establishing the first OOB communication link, exchange a plurality of OOB synchronization parameters with the first anchor;
transmit first UWB compatibility information to the first anchor, the first UWB compatibility information being representative of first communication capabilities associated with the first UWB tag;
establish a first UWB communication link with the first anchor based at least in part upon the first UWB compatibility information;
establish a second UWB communication link with a second anchor of the plurality of anchors based at least in part upon the first UWB compatibility information;
exchange a first plurality of UWB synchronization parameters with the first anchor and the second anchor; and
determine a first location of the first tagged device in a space based at least in part upon the first plurality of UWB synchronization parameters exchanged with the first anchor and the second anchor.
