1. A system for remote activation of a device, the system comprising:
- a remote unit comprisinga transceiver fortransmitting a pilot signal for use in determining a range of the remote unit from the device, wherein the pilot signal lacks a command for activation of the device,receiving a signal indicative of a range from the device, andtransmitting a command signal according to one of a first transmission protocol and a second transmission protocol, wherein the first transmission protocol comprises a first data rate and the second transmission protocol comprises a second data rate different from the first data rate, anda controller forcomparing the range to a threshold,selecting the first transmission protocol for use in transmitting a command signal when the range exceeds the threshold, andselecting the second transmission protocol for use in transmitting a command signal when the range fails to exceed the threshold,wherein the controller compares the range to a threshold and selects one of the first and second transmission protocols for an initial command signal transmission following a user input to the remote unit.

Abstract
A system and method for remote activation of a device includes, in one embodiment, receiving a signal indicative of a range from the device, comparing the range to a threshold, selecting a first transmission protocol when the range exceeds the threshold, selecting a second transmission protocol when the range fails to exceed the threshold, and transmitting a command signal according to the selected first or second transmission protocol.

14. A method for remote activation of a device, the method comprising:
-
receiving a signal comprising data representing a range from the device; comparing the range to a threshold; selecting a first transmission protocol when the range exceeds the threshold; selecting a second transmission protocol when the range fails to exceed the threshold; and transmitting a command signal according to the selected one of the first transmission protocol and the second transmission protocol, wherein an initial command signal transmission following a user input is based on the comparison of the range to a threshold and the selection of one of the first and second transmission protocols, and wherein the first transmission protocol comprises a first data rate and the second transmission protocol comprises a second data rate different from the first data rate. - View Dependent Claims (15, 16, 17)
