Air Force Cross-Bands Radio Networks for Interoperability Between Military Groups

With several armed forces training together in the same area, the need for good communication between groups was essential but each group had its own dedicated frequencies. A simple method to combine dedicated radio channels was required so that personnel could talk directly to each other. The key to success would be a solution that was simple to deploy and was highly reliable.

Air Force cross-bands Radio Networks for Interoperability between Military Groups

The 619EI audio bridge, the base was easily able to combine the group’s radio frequencies. Using the existing distributed fibre optic network, audio from repeater sites was centralized. The audio output from the network was 4‐wire E&M which plugged directly into the 619EI 6 port audio bridge. Through front panel DIP switches, the required bridging matrix was easily setup. Balancing audio from different radio sources was made straightforward with both input and output level control available to the technician.

The 619EI audio bridge has proven a reliable, low‐maintenance solution for over 5 years and provided the interoperability required, despite thunderstorms and lightning strikes. Based on this history, the radio network continues to be upgraded and now other military installations are reviewing the solution.
