with someone else via the on-base headset or a party-line or matrix
connection with the base.
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 the ECS Instruction
manual for setting up a system.
DOING A SITE SURVEY TO DETERMINE
COVERAGE AREAS
Some Eclipse 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 you to set up the system successfully to
meet your 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 you to set up
an optimal system.
TESTING COVERAGE AREAS OF INDIVIDUAL
ANTENNAS
1. Place the Eclipse matrix in a convenient location. Register one
beltpack to the matrix.
2. Place one antenna in the center of the coverage area.
3. Put the beltpack into “site survey mode” by first pressing the power
button on the back of the beltpack, and then simultaneously
pressing the two front-panel scroll buttons.
• When you do this, the beltpack’s display shows the “site survey”
screen. Figure 4-1 shows a beltpack’s site survey screen.
4. Walk around the antenna with the beltpack, monitoring the
beltpack’s signal strength and error rate at various distances.
The signal strength is shown in the Received Signal Strength
Indication (RSSI) field in the leftmost lower corner of the beltpack’s
display. The error rate is shown in the ERR field in the middle of the
display.
