SAFETY WARNINGS AND ADMONISHMENTS

Throughout this manual, important safety warnings and admonishments are included to
warn of possible hazards to persons or equipment. A safety warning identifies a possible
hazard and then describes what may happen if the hazard is not avoided. The safety
warnings – in the form of Dangers, Warnings and Cautions must be followed at all
times. These warnings are flagged by the use of a warning icon, usually the triangular
alert icon seen below. The exclamation point within the triangular alert icon is intended
to warn the operator or service personnel of operation and maintenance from factors
elating to the product and its operating environment, which could pose a safety hazard.

GENERAL SAFETY WARNINGS CONCERNING USE OF THIS SYSTEM

Always observe standard safety precautions during installation, operation and
maintenance of this product. Only a qualified and authorized personnel should carry out
adjustment, maintenance or repairs to the components of this equipment.

Danger: Electrical Shock

This equipment is usually installed outdoors. Wet conditions increase the
potential for receiving an electric shock when installing or using electrically
powered equipment. To prevent electrical shock when installing or modifying
the system power wiring, disconnect the wiring at the power source before
working with uninsulated wires or terminals.

2. FUNCTIONAL DESCRIPTION

2.1 GENERAL

This repeater is designed to help improve communications signal by extending the
coverage of a base station. The Donor (Base) antenna receives the signal from a base
station and conveys it to the CDMA Repeater. The Repeater amplifies the signal.
After amplification, the signal is passed through to the Mobile antennas. Conversely,
signals from handsets are amplified and retransmitted by the Repeater to the base
station.

2.2 FUNCTIONAL DESCRIPTION

The incoming signal processing in the CDMA Repeater is processed similarly for
both the Uplink and Downlink paths. Figure 1 provides a functional block diagram of
the CDMA Repeater.

Figure 1: CDMA Repeater - Block Diagram

The block diagram showed in Figure 1 illustrates the overall functionality of the
CDMA Repeater. Dekolink’s programmable CDMA Repeaters employ advanced
up/down conversion Intermediate Frequency (IF) Surface Acoustic Waves (SAW)
filtering architecture. This new technology offers distinct advantages over
conventional repeaters, when high adjacent selectivity and spectrum purity is
required.

The Channeler Module (center unit) consists of dual Radio Frequency Up/Down
Converter sub-modules for Downlink and Uplink paths. The Channeler amplifies the
received RF signals and converts them into an intermediate frequency (IF). The IF
outputs are connected to a SAW Filter. The IF outputs are converted back to the
original RF frequencies.

The cellular modem is an option for remote monitoring and repeater parameters
control.
