Abstract
A data communication device includes both a two-way communications component having a first receiver and transmitter, and a second receiver. The second receiver activates the two-way communications component from a dormant state upon receipt by the second receiver of a wake-up broadcast that includes a wake-up identifier of the data communication device. A method of providing information via the second receiver—which information is auxiliary to the wake-up of the two-way communications component—includes transmitting a wake-up broadcast capable of being received by the second receiver. The wake-up broadcast includes a data construct including a wake-up identifier and the auxiliary information. The wake-up identifier may or may not be a wake-up identifier of the data communication device. Nevertheless, the auxiliary information is received and recorded by the data communication device via the second receiver with the two-way communications component remaining in the dormant state.
