wireless beltpacks in the vicinity of the active transceiver/antenna will
be connected to the system and their displays will show labels and
other information.
Using both transceiver ports, a basestation may be connected with up
to two transceiver/antennas via a direct connection with the
basestation. For the best, most reliable coverage, it is advisable to use
a minimum of two transceiver/antennas in any installation, positioned
in different locations in the coverage area. When more CEL-TA’s are
required to support a larger coverage area or more wireless beltpacks,
an antenna splitter will need to be introduced between the basestation
and the transceiver/antennas.
Note: In some situations, particularly in outdoor venues,
interference from non-DECT sources can severely reduce
the range of the system. In these cases we recommend a
site survey as described in Chapter 8, “Installing a System”.
CONNECTING TRANSCEIVER/ANTENNAS WITH A
SPLITTER (PD2203)
A splitter (PD2203) will connect up to five transceiver/antennas to one
of the transceiver ports on the CellCom basestation, creating up to five
coverage zones that can be overlapped to make large areas where
CEL-BP wireless beltpacks can have continuous coverage. The use of
the splitter also extends the distance that the CEL-TA transceiver
antennas can be located from the basestation to 2,000 meters (6,400
feet) if 24AWG cable is used or 1,000 meters (3,200 feet) if 26AWG
cable is used (assuming the same cable type is used to connect the
antenna to the splitter and the splitter to the basestation).
Note: It is recommended that shielded CAT-5 cable is used.
For example, a splitter can be used to connect to a CellCom
basestation that is located in a production truck outside an arena or
stadium, with a single CAT-5 cable going to the splitter which is then
located just inside the stadium. From that splitter, up to five CEL-TA
transceiver/antennas are distributed throughout the stadium to create
wide coverage – each with a run of CAT-5 cable back to the splitter. A
similar arrangement may be used in a large theatre or performing arts
facility.
The connection between a transceiver port on the CellCom
basestation and a PD2203 splitter is accomplished with standard
4-pair CAT-5 data cable with RJ-45 connectors. It is connected to the
port labeled MATRIX on the splitter. This cable can be as long as 1,000
meters (3,200 feet) if 24AWG cable is used or 500 meters (1,600 feet)
if 26AWG cable is used. The splitter must be locally powered via its DC
IN connector, using the in-line external universal power supply. The
RJ-45 ports on the splitter labeled “1” through “5” are the connections
to the CEL-TA transceiver/antennas. Transceiver/antennas connected
