PCS Band Multi Carrier Cell Extender
CCI Model Number CE-1819-125MC-XXXX
USER’S GUIDE
Product Description:
Communication Components, Inc. PCS CDMA Multi-carrier Cell Extender
improves the performance of CDMA Base Stations (BTS) in indoor and outdoor
locations, allowing for cost efficient implementation of high capacity radio
networks.
By increasing both the downlink power and receive sensitivity, CCI’s Cell
Extender increases the overall coverage area and improves the performance of
the site.
Operation Description:
CCI’s Multi-channel CDMA Cell Extender is designed to improve overall site
performance by boosting both forward and reverse link parameters in a balanced
manner. The system is designed to provide 125 Watts of usable CDMA output
power per sector antenna (63 W per sector antenna for Canada) and can serve
up to three sectors with two feeder antennas per sector. As such, a CE-1819-
125MC system used in six-carrier sector with 3 carriers per antenna can delivers
40 W per carrier (21 W per carrier for Canada).
• CCI supplies Cell Extender cabinet that requires a dual 30A 208/240V breaker
and two batteries for backup purposes.
RF Connection
Cell Extender cabinet must be bolted to the frame.
• Connect Cell Extender input Tx/Rx and Rx ports (connectors type N located on
the connectors plate inside of the main cabinet) with DO and D1 ports of BTS in
the proper sector using two DIN-N jumpers.
• Connect Cell Extender output Tx/Rx and Rx ports (Bias-T blocks with DIN
connectors located on the connectors plate inside of the main cabinet) with Tx/Rx
and Rx ports of Main Lines of the proper sector using two DIN-DIN jumpers.
AC Connection
• 20A Breakers must be installed in the main electrical box (or A-box).
• 3-conductor AC-wire gage 12-14 must be run through metal conduit to the
electrical junction box inside of the CCI Cell Extender cabinet. The entry point to
this junction box is from the bottom of the cabinet via a corrugated shield.
• Run a standard 6 gauge grounding wire from the site’s main grounding bar
(Bus-bar in the A-box) to the CCI Cell Extender cabinet and secure it to the
electrical junction box inside the cabinet.
• Run Alarm cable through 1” conduit to the alarm card in BTS. Site technician
will make actual connection.
• Install the batteries:
a. Place the batteries in the bottom of the cabinet
b. Use the short jumper to connect the positive terminal of one battery to the
negative terminal of the other battery.
c. Cover the battery terminals with the supplied terminal boots.
• Confirm proper electrical connection
a. Turn off all breakers on PSU modules located in the Cell Extender cabinet;
b. Turn on breakers in the main electrical box (A-box)
c. Confirm that the green Power LED on PSU’s turn on.
Setting the RF Output Power on the CE-1819-125MC-XXXxX Cell Extender
The RF output power is adjustable on the Cell Extender. Use Gain Control Block that
contains a set of the input signal attenuators. The user must adjust the RF input power to
the Cell Extender connecting the proper pad such that the combined RF output power
level of any number of the individual carriers does not exceed the levels shown below in
order for the RF output spectral emissions to be compliant with the FCC spurious
emissions limit of -13 dBm outside of the assigned frequency block. These levels must
not exceed

This equipment complies with Part 24 of the FCC rules. Any changes or modifications
not expressly approved by the manufacturer could void the user's authority to operate the
equipment.
In order to comply with FCC rules for RF exposure, it must be observed that the antenna
connected to this equipment be fixed on an outdoor structure and that it must have a
minimum separation distance of 10 meters between it and any person.
In accordance with Industry Canada RSS-131, the manufacturer's rated output power of
this equipment is for single carrier operation. For situations when multiple carrier signals
are present, the rating would have to be reduced by 3.5 dB, especially where the output
signal is re-radiated and can cause interference to adjacent band users. This power
reduction is to be by means of input power or gain reduction and not by an attenuator at
the output of the device.
PCS block filters must be installed to achieve compliance with part 24 spurious emission
limits. Filters are manufactured by Clearcomm Technologies, part number CCFA-174-
XX . Connect the output filter port marked “BTS “ with the port on By-Pass module
marked “To BTS Duplexer”. Connect the filter port marked “ANT” to the By-Pass
module port marked “ From ANT Duplexer”. Connect the filter port marked “AMP
OUT” with corresponding attenuator port on Gain Control module. Connect filter port
marked “AMP IN” to the Amplifier module port marked “ RF OUT”.
