ABSTRACT:
A communication system includes a first communication module, and a second communication module. The first communication module may receive a first type of communication signal (e.g. a mobile telephone signal) and convert it into a second-type of communication signal (e.g., a millimeter wave radio signal). The first type of communication signal may be a mobile telephone signal from a first fire fighter's mobile telephone who is located outside of the building. The first communication module may transmit the second-type of communication signal to the second communication module.
