Abstract
Disclosed herein is a method for data communication between a wireless-communication system and one or more wireless-communication devices. The wireless-communication system broadcasts a standard pilot signal over a pilot channel. The method comprises (a) the wireless-communication system transmitting a first broadcast-mode message in a coverage area of the wireless-communication system, wherein the first broadcast-mode message indicates that the wireless-communication system will be operating in an alternative broadcast mode, and (b) the wireless-communication system operating in the alternative broadcast mode. Operating in the alternative broadcast involves (i) generating a modified pilot signal comprising the standard pilot signal and a data message inserted in the standard pilot signal and (ii) broadcasting the modified pilot signal via the pilot channel, which enables a wireless-communication device receiving the modified pilot signal to extract the data message therefrom.
