to interact with one another to exchange information according to a prescribed method in
order to achieve predictable results.
Megahertz (MHz) – A common technical term that refers to the frequency of the radio.
One MHz equals 1,000,000 cycles, or hertz, per second.
PSWN – Public Safety Wireless Network.
Simplex – Communications circuit in which flow of information can proceed in only one
direction at a time; compare to duplex.
Trunked Systems – Systems where multiple channel pairs are integrated into a single
system. When a user wants to transmit a message, the trunked system will automatically
select a currently unused channel pair and assign it to the user, decreasing the probability
of having to wait for a free channel for a given loading.
How have other departments implemented new 800 MHz radio systems?
Many fire departments across the nation are updating their current obsolete radio
systems with state of the art 800 MHz trunked radio systems. The failure or success of
implementing these new radio systems have been determined more or less based on
proper planning, training and involvement by the users.
Phoenix firefighter Tim Hill reported that they fought for and won, representation
on steering committees that were designing the system. “The result will be the launch of a
properly-funded and reliable radio system in which the firefighters have confidence,
which is extremely important,” he said. “Funding for the proper radio infrastructure and
