SMARTZONE OPERATION
This section outlines the SmartZone
TM
operations of
your radio. All references to what is shown on the
display is only valid for Model II radios. Throughout this
section, the display below
is used to indicate the radio’s home display.
BENEFITS OF SMARTZONE
Radios that operate in a SmartZone system enjoy the
benefits that SmartZone brings over AMSS operation.
Like AMSS, SmartZone is a wide-area coverage
system that allows multiple sites to be operational in
the system. SmartZone brings several enhancements
over AMSS operation, as in the following.
1. Dynamic Site Assignment
Allows the zone controller to dynamically assign
channels at sites where required, as opposed to
bringing up channels at all of the sites as AMSS
systems do.
2. Variable Density Sites
SmartZone allows sites to have varying numbers
of channel resources to accommodate low-density
areas as well as high-density areas.

3. Automatic Site Registration/De-registration
SmartZone radios automatically send in their unit
IDs and current mode selections upon power up,
power down, site switches, mode changes, and
when they exit emergency operation. This allows
the zone controller to know where the radio is at
all times, and what mode the radio has selected.
4. Critical Site Assignment
One or more sites can be designated as critical
sites. This instructs the zone controller to ensure
that every site designated as a critical site must
have available channel resources, before a
channel is given to a radio wishing to be identified
as a critical site user. Otherwise, a busy is sent to
the unit.
5. Busy Override
This feature allows a SmartZone radio to send a
busy override request if a busy is issued. The
zone controller sends a grant even though not all
of the sites may have available channel
resources.
