Abstract
A system can be for use with a number of reference tags disposed at respective reference locations in a coverage area. The reference tags can be configured to form a wireless mesh network. A system can include a first tag configured to communicate with the reference tags. The first tag can operate in a sleep mode and includes a motion sensor. The first tag is woken out of the sleep mode on a first periodic basis to communicate with the reference tags. The first tag is woken out of the sleep mode at a second periodic basis in response to motion signal from the motion sensor. The second periodic basis is more frequent than the first periodic basis. The system can also include a positioning system configured to receive data related to the communication between the first tag and the reference tags. The positioning system can be configured to process the data to determine a location of the first tag.
