Trunked radio systems actively assign free radio frequencies
to radio users as needed. This greatly improves the efficiency
of spectrum usage.
If you are considering the use of a shared radio system
for your business, be sure it is of a Trunked type service.
This will increase your chances of being able to get a clear
frequency when you need it.
Trunked radio systems often allow one-to-one and telephone
interconnected calls in addition to the group call.
Most trunked radio system operates provide use of their
systems to many businesses at a flat rate per month per
radio. This can make budgeting communications costs easier
than per minute services.
