Determining Coverage Areas - Clear-Com ECLIPSE DIGITAL WIRELESS User Manual

Note: To meet FCC
emissions requirements,
you must fit a ferrite on
any CAT-5 cable plugged
into either of the two ports
labeled "tranceivers." The
ferrite should be fitted at
the E-Que card end of the
CAT-5 cable. Position the
ferrite as close to the
E-Que card as possible.
The manufacturer of the
ferrite is Wurth
Elektronix. The part
number is 742 711 32.

2. Run 4-pair CAT-5 cable from the splitter to each of the transceiver/antennas.
3. Make sure that the local power supplies are plugged into the antennas, unless
they are close enough to the matrix to draw power from the attached CAT-5
cable.
You will know that a transceiver/antenna has sufficient power from the cable if
the green power LED and the yellow data LED light up. If you have several
longer runs and are attempting to power the transceiver/antennas from the base /
splitter connection, check each one again when the are all connected. The local
powering for the transceiver/antenna is recommended in most cases to provide
the most reliable long-term Eclipse installation.
Note that 4-pair CAT-5 cable with RJ-45 connectors on each end is specified for
connection between the E-Que card and the transceiver/antennas. Use of other
cable can result in markedly shorter distances of cable runs and other possibly
other performance problems.
During the initial system setup, before walking through the system with a
beltpack to check for gaps in coverage, it is wise to avoid "permanently" installing
the transceiver/antennas. Hold them in place in some temporary way until their
optimal position is determined.

DETERMINING COVERAGE AREAS

After you have initially set up the transceiver/antennas and splitters, you can
proceed to test the coverage areas and re-locate antennas and splitters, if
necessary, for optimal coverage.
To determine coverage areas:
1. Once the base, splitter(s), and transceiver/antennas have been placed and
wired, turn on a beltpack (assuming that it has been registered with ECS) and
walk the coverage area – ideally speaking 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.
