1. A multi-radio bridge comprising:
- (a) a first component and a second component and a transmission means linking said first component and said second component wherein said first component and said second component are not in the same unit;
(b) a first input for receiving and transmitting an RF audio signal in said first component wherein said first input has at least a two wire conductive cable;
(c) a first audio to IP conversion unit in said first component wherein said first audio to IP conversion unit converts and reconverts audio to IP or IP to audio;
(d) a first Non licensed ISM Band transceiver disposed in said first component;
(e) a second input for receiving and transmitting an RF audio signal in said second component wherein said second input has at least a two wire conductive cable;
(f) a second audio to IP conversion unit in said second component wherein said second audio to IP conversion unit converts and reconverts audio to IP or IP to audio; and
(g) a second Non licensed ISM Band Transceiver disposed in said second component.

Abstract
A two component highly portable and lightweight system for extending the transmission capabilities of Land Mobile Radio systems into areas lacking coverage due to structures, depth below the earth'"'"'s surface, or varying terrain or other dead zones lacking coverage. The system utilizes the Radio over IP protocol to transfer two-way audio from one radio to another radio for re-broadcast inside a dead zone over a 900 MHz Ethernet-based point-to-point wireless link. The novel system includes RF to TCP/IP conversion and digital data transmission followed by a TCP/IP conversion to RF radio link and provides components and a method for bridging RF radio into dead zones.
