Abstract
A pager receives a wireless telecommunication message from central paging terminal. Upon successful transmission of the message to the pager, the message is acknowledged initiating transmission of an acknowledge signal from the pager. The pager transmits the acknowledge signal to one of a variety of different secondary transmission sources. The secondary transmission source then relays the acknowledge signal back to a receiver associated with the central paging terminal. The acknowledge signal is either physically initiated by depressing a switch on the pager or is automatically initiated by the pager upon receiving the message. Energy efficiency of the pager is further increased by periodically broadcasting and polling for available secondary transmission sources.
