LOCATING DEVICE AND SYSTEM USING CELLULAR TECHNOLOGIES

摘要

A system and device for locating which utilizes cellular technology. The remote pager/cellular device (101) comprises a receiver (102) which receives a pager signal (211) independently of the cellular network. A cellular transmitter (109) is activated in response to such activation signal (211) and provides a cellular signal (213) which is received by the cellular network. The cellular signal (213) can be used to locate the device (101). The cellular transmitting portion (109) is only active when needed, so that the power supply is conserved.
