Abstract

The invention discloses an apparatus (10) for transmitting a communication signal, across one or more pre-existing frequency channels or bands that carry a transmission signal, comprises a memory for storing at least one pre-existing frequency channel or band together with information relating to a strength of the transmission signal carried by the at least one pre-existing frequency channel or band. A controller (24) generates a communication signal to be transmitted across at least one of the channels or bands at a strength sufficient to over-broadcast the transmission signal carried. A mixer (26) receives each of the communication signals generated by the controller (24) and combines said communication signals into a combined mixed communication signal (15). A transmitter (16) transmits the combined mixed communication signal (15) across the at least one pre-existing frequency channels or bands either to replace or add the transmission signal carried by the at least one pre-existing frequency channel.

Description

[0001] related application [0002] This application claims priority from Australian Provisional Patent Application No. 2014900324 filed 4 February 2014, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to an information communication system for transmitting information to individuals, and more particularly, to an information communication system that can be used in a mobile or stationary manner, capable of selectively transmitting information to individuals through a communication device. Background technique [0004] The ability of an authority or government agency to provide an effective communication system to communicate with the public is fundamental to good governance and public safety. The information to be communicated through this communication system can range from general updates on changes in public services to important information related to warning and evacuation of potential...
