has been registered with the basestation) and walk the coverage
area – ideally speaking with someone else via the on-basestation
headset or a party-line or matrix connection with the basestation.
Alternatively, use the “site survey” mode on the beltpack (see “Doing
a Site Survey to Determine Coverage Areas” below). It is often best
to begin with one antenna in place, and then place additional units to
enhance coverage.
2. Walk through all of the areas where beltpack users will typically be
moving, and note any areas of weak signal, dropout, or
disconnection from the system. Pay special attention to the overlap
areas between antenna coverage zones, making sure sufficient
signal strength is there from each of the transceiver/antennas to
make a clean handoff between them for the beltpack.
3. Finally, when the coverage zones have been properly and effectively
set up, it is time to program the system. See Chapter 5,
“Programming a System from the Basestation” for instructions.
DOING A SITE SURVEY TO DETERMINE
COVERAGE AREAS
Some CellCom users may want to test coverage areas more
extensively before setting up a a complete system. Testing a system in
the setting in which it will be located helps to set up the system
successfully to meet operational needs. Factors in the local setting
may affect the areas a system can cover, so it is important to plan a
site setup accordingly.
Doing a complete site survey, as described below, helps to set up an
optimal system.
TESTING COVERAGE AREAS OF INDIVIDUAL
ANTENNAS
1. Place the CellCom basestation in a convenient location. Register
one beltpack to the basestation.
2. Place one antenna in the center of the coverage area.
3. If the DECTSync program is being used ensure the serial cable is
connected. If no serial cable is connected the beltpack may not
initially enter “site survey” mode (see below).
4. Put the beltpack into “site survey mode” by first pressing and holding
the power button on the back of the beltpack, and then pressing the
right front-panel scroll button.
• When this is done the beltpack’s display shows the “site survey”
screen. Figure 9-1 shows a beltpack’s site survey screen.
• If the beltpack does not enter “site survey” mode (for example
because no serial cable is present) press the right front-panel
scroll button again with the beltpack still switched on. The
beltpack will then be forced into “site survey” mode.
