Abstract
A system can identify a first position of a tag in a clinical environment based on first times at which first receivers received a first wireless signal from the tag. The system can estimate a second position of the tag in the clinical environment based on second times at which second receivers received a second wireless signal from the tag. The system determines that a boundary is located between the first position and the second position, defines a path range around the first position of the tag based on an expected movement of the tag during a time interval between the first and second wireless signals, determines that the boundary lacks a door within the path range, adjusts the second position of the tag based on the boundary map, and transmits a message indicating that the tag is located at the adjusted position at the second time.
