•There are 6 ways to achieve interoperability in a system:
•
•
1.Swap
radios
2.
2.Use
talkaround frequency
3.
3.Use
municipal mutual aid frequencies
Speaking Points
1. Swap Radios
•Swapping radios is the low-tech version of interoperability.It allows you to hear and speak with other
partners but is limited by available equipment and extra bulk.
2. Talkaround Frequency
•Limited by range, equipment and preplanning
•A talkaround frequency is a frequency that has been already set aside
for use by multiple responders at a scene.It does not use a repeater and is limited by preplanning (all
responders must have the frequency preprogrammed into their radios) and
distance.
3. Mutual Aid Channels
•Commonly available
•Limited by equipment, preplanning and susceptibility to overload
•Mutual aid channels are talkaround channels supported by
repeaters.They must be preplanned
also, but are less limited by distance.They are vulnerable to overload, however, if too many responders start
using the same channel.
