Abstract
A system and method of wireless communication. An activator comprises a first radio that transmits an activation message; a first microprocessor; a first memory component; and a first timer. A remote device comprises a second radio that periodically enters into an activation period of operation and a de-activation period of operation in order to conserve power; a second microprocessor; a second memory component; and a second timer. The first radio transmits the activation message repeatedly and continuously for a period at least equal to the sum of the activation period of operation and the de-activation period of operation of the second radio. At least one complete activation message is transmitted by the activator during every period of time allotted for activation of the second radio. The second radio increases a frequency of activation of the second radio upon receipt of a designated activation message from the first radio.
