It may be located up to 1,000 meters from the base station, creating a coverage
area for five CEL-BP wireless beltpacks in that location. The port is able to
provide the required power to the transceiver/antenna at a distance of up to 300
meters (approximately 900 feet); beyond that distance, the CEL-TA
transceiver/antenna must be locally powered via its in-line external universal
power supply.
To know that a CEL-TA transceiver/antenna is active, observe the green power
LED and the yellow signal LED on the face of the unit where the RJ-45
connector is connected. Both must be lit. Also, 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 base station may be connected with up to two
transceiver/antennas via a direct connection with the base. 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 base station
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 (CEL-SP)
A splitter (CEL-SP) will connect up to five transceiver/antennas to one of the
transceiver ports on the CellCom 10 base station, 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 base to
beyond 1,000 meters (3,200 feet).
For example, a splitter can be used to connect to a CellCom 10 base 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 10 base station and a
CEL-SP 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). 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 to the splitter can be powered at a distance of up to 300 meters (900
feet); beyond that distance they will need to be locally powered.
