1. A computer-implemented method comprising:
identifying a plurality of ultra-wide band (UWB) anchors for which a mobile device has had a signal strength above a predetermined threshold during a predetermined period of time, the plurality of UWB anchors not including a primary UWB anchor with which the mobile device has previously performed UWB ranging;
selecting one of the plurality of UWB anchors as a new primary UWB anchor for the mobile device based on a relative collision tolerance mapping for the new primary UWB anchor and at least one other UWB anchor within a UWB range of the new primary UWB anchor; and
sending a command that causes a UWB ranging procedure to be performed between the mobile device and the new primary UWB anchor.
