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.
