Abstract
A system and method is provided for determining the location of an object. A first transceiver is associated with an object to be located. The first transceiver comprises a first transmitter and a first receiver operable to transmit and receive signals using a first transmission protocol and a second transmitter operable to transmit signals using a second transmission protocol. A first signal is transmitted using the first signal transmission protocol and is received by the first receiver. The second transmitter is then used to transmit a second signal using the second transmission protocol in response to receipt of the first signal and the second signal is then processed to determine the location of the object. In some embodiments, the first transmission protocol is in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard and the second transmission protocol is in accordance with a Ultra-Wide Band (UWB) standard.
