Abstract

Dual-mode position-locating tag, including: a transmitter module configured to communicate with a Wi-Fi network; a transceiver module configured to communicate with a non-Wi-Fi network; a processor coupled to the transmitter module and the transceiver module; and at least one location sensor coupled to the processor, the location sensor coupled to a secondary technology receiver. The transmitter module may transmit a signal to produce a first location measurement. The secondary technology receiver may receive a signal usable to calculate a second location measurement that is more accurate than the first location measurement.
