General Information:
Communication Component Inc.’s Cell Extender products are designed to extend the range
and coverage area of Ericsson RBS 2301 Micro Base Stations in all GSM PCS applications.
The Cell Extender boosts the output power of the RBS 2301 to match the levels of
conventional Base Stations such as the RBS-2000 allowing for cost efficient implementation of
high capacity radio networks. It also provides low-noise amplification of the receive signal to
improve system sensitivity and to maintain a balanced link of the transmit and receive signals.
The Cell Extender is easy to install, requires no maintenance, and is fully compatible with
Ericsson Base Station equipment. The Cell Extender offers the maximum installation flexibility
by allowing the RBS2301 to be physically distanced from the antenna and mounting structure.
This overcomes the key key installation drawback of the RBS2301 which requires both a T1
connection and an AC connection on the mounting structure. Three installation options are
available:
• Configuration 1 - The CE-1819-20 can be mounted on the same mounting structure
directly underneath the Micro Base Station. This option is ideal when an existing
RBS2301 site is being upgraded with a Cell Extender or when both AC and T1
connections are available on the mounting structure.
• Configuration 2 - The RBS2301 is installed at ground level or indoors and the Cell
Extender is mounted on the mounting structure, in close proximity to the antenna. This
configuration is ideal for environments where AC lines and T1-connections are not
easily available on the mounting structure or when it is desired to keep the RBS2301
indoors. For this configuration, the Cell Extender should be ordered with the Remote
Power Option which includes a Bias-t and Remote Power Supply module to provide DC
power to the Cell Extender over the Coax cable.
• Configuration 3 - Both the RBS2301 and the Cell Extender are installed at the ground
level or indoors. This is intended for applications where it is impractical to install any
equipment other than the antenna on the mounting structure.

Cell Extender System Specification
Description:
The Cell Extender is specifically designed for compatibility with the Ericsson RBS 2301
Base Station Equipment and is ensured to maintain the integrity of the GSM signal
amplification. This is achieved by utilizing state-of-the-art LDMOS technology for
amplification, monolithic Gallium-Arsenide technology low noise receive
particular emphasis on low system group delay to minimize Bit-Error-Rate (BER) of
transmissions.
The Cell Extender block consists of a single compact unit with four RF connectors
single AC line for power. It is housed in a moisture proof NEMA 4X aluminum
enclosure with integrated heat sinks and is suitable for either outdoor or indoor
The Cell Extender is designed to boost both low power tranceivers (both cells)
provided with RBS 2301. It contains redundant low noise amplifiers to boost the
signals, redundant LDMOS-based high power amplifiers to boost the transmit signal,
duplexers, an integrated power supply and alarm/control circuitry to monitor the
the unit. The Cell Extender is powered by a conventional 110/220 VAC source or
optionally DC-powered via the Coax cable using Remote Power
