MICROPOWER PAGING CONTROL OF COMMUNICATIONS FUNCTIONS

摘要

A method for remotely activating a beacon-burst transmitter. In a first embodiment, the method includes steps of (i) receiving a first paging signal by a micropower paging receiver (10); (ii) interpreting said first paging signal by a microprocessor (22) coupled to said micropower paging receiver (10); (iii) activating a power switch (18) coupled to said microprocessor (22) and said micropower paging receiver (10), said power switch (18) for enabling a power source (16); and (iv) transmitting a beacon signal by a beacon-burst transmitter coupled to said power switch (18), said microprocessor (22) and said micropower paging receiver (10). The method desirably further comprises steps of (v) activating a global positioning system receiver in response to said first paging signal; (vi) obtaining a position fix from said global positioning system receiver; and (vii) transmitting said position fix by said beacon-burst transmitter.
