Abstract
A tag includes a communication interface that is configured to receive and transmit wireless transmissions, a movement detector and a digital logic circuit configured to perform operations. The operations may include broadcasting wireless transmissions comprising a tag ID of the tag from the communication interface according to a transmission pattern. A stationary movement pattern of the tag may be detected with the movement detector. The operations may further include adjusting the transmission pattern responsive to detecting the stationary movement pattern. A confirmation from a computing device indicating that information for the tag ID has been received by a server tracking the tag. The adjustment to the transmission pattern may also be responsive to receiving the confirmation. The tag broadcasts wireless transmissions according to the adjusted transmission pattern.
