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 100 Watts of usable CDMA output power per sector antenna and can serve up to three
sectors with two feeder antennas per sector. As such, a CE-1819-100MC system used in six car-
rier sector with 3 carriers per antenna can delivers 32 W per carrier.
The CE-1819-100MC was specifically designed for very simple interface with micro and mini base
stations without any need of retrofitting the original BTS equipment. The system can be pad
mounted at any convenient location or pole-mounted when site space is limited.
The Cell Extender system consists of two major blocks that can be easily connected during the
initial installation of the BTS or as a retrofit to an operational BTS. The tower top amplifier (TTA)
unit is mounted at the top of the tower next to the Antennas and is responsible for improving the
uplink signal from mobile users and increasing the receive sensitivity of the BTS. The TTA is
housed in a moisture proof NEMA 4X enclosure and contains low noise receive amplifiers and du-
plexers. The TTA is powered via DC power that is coupled onto the center conductor of the coax
line. It also communicates is operational and alarm status three multi-carrier sectors via the coax
line. The Ground Level Unit (GLU) is an outdoor cabinet designed to serve up to three sectors
with up to six CDMA carriers per sector. Each sector section consists of high power Duplexers,
multi-channel power amplifiers, gain control and bypass circuitry which is activated in case of fail-
ure of any critical component of the system. CCI’s Multi-channel CDMA Cell Extender employs a
unique BTS transmit power recovery technology (patent pending) that allows up to a 25% in-
crease in the efficiency of the system.

General Information
Communication Components, Inc. PCS
CDMA Multi-carrier Cell Extender im-
proves the performance of CDMA Base
Stations (BTS) in indoor and outdoor lo-
cations, allowing for cost efficient imple-
mentation of high capacity radio net-
works. 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. The CE-1819-100MC provides up to
100 Watts of combined CDMA output
power per feeder line/antenna.
