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.
Caution: RF Exposure
Installation of an antenna must comply with the FCC RF exposure
requirements. Refer to paragraph 4.4.

1. INTRODUCTION
1.1 GENERAL
Dekolink’s Digital Repeaters are channel selective amplifiers that amplify signals bidirectionally between mobile phones and base stations, in cellular and other wireless
mobile telephone systems. Dekolink’s Digital Repeaters employs advanced Digital
Signal Processing (DSP) technology that provides significant advantages over
conventional repeaters.
The Digital Repeaters can be monitored locally or remotely via Dekolink’s Windowsbased Network Management System - RMT software (Refer to the RMT Software
User's Guide for more information).
1.2 APPLICATIONS
Dekolink’s Digital Repeaters introduce new system capabilities that enable a wide
variety of applications particularly when adjacent channel selectivity and/or very high
spectral purity are required. The repeaters provide a solution to situations in which
flexible, high quality and high resolution filtering methods are necessary.
Dekolink’s Digital Repeaters help solve these area coverage problems:
•
•
•
•
•
•
Repeaters also address special application needs such as traffic balancing.
1.3 FEATURES
Some of the of the Dekolink Digital Repeaters' features are listed below:
•
•
Capacity enhancement for existing coverage, •
Extended coverage for rural and isolated areas
Improved in-building coverage
Frequency shift (FSR), sometimes defined as frequency translation or
conversion repeater application
Hole filler application whenever there is no coverage of a particular spot in
the cell site (due to terrain topography or urban structures that shadow areas)
Cell extension to improve the coverage of an existing cell
Repeater On Wheels (ROW) application whenever temporary capacity
enhancement is requested, as during a major event when large crowds gather
50W Downlink (1dB compression point) output power, i.e., 10W Downlink
composite output power
90 dB RF gain
•
Flexible, software controlled, filter array
•
One to eight programmable filters
•
Independent programmable bandwidth for each filter
(12.5 to 250 KHz)

2. FUNCTIONAL DESCRIPTION
2.1 GENERAL
This repeater is designed to help improve communications signal and coverage by
extending the coverage of a base station. The outdoor Donor (Base) antenna receives
the signal from a base station and conveys it to the Digital Repeater. The Repeater
amplifies the signal.
After amplification, the signal is passed through to the Mobile antennas, either
outdoor or indoor. 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 Digital Repeater is processed similarly for both
the Uplink and Downlink paths.
Figure 1 provides a functional block diagram of the Digital Repeater.
Figure 1: Digital Repeater - Block Diagram
The incoming RF signal from either the Base antenna (from the BTS) or from the
Mobile antenna (from the mobile handset) enters the Repeater and is first filtered by
the Duplexer. The incoming signal is amplified by an Automatic Gain Control (AGC)
amplifier, then down-converted.
The input RF signal is then sampled and converted into a digital signal. This digital
signal is filtered using fast parallel logic. The Repeater generates up to eight
separate, programmable, and independent filters using digital processing techniques.
These programmable filters sort the digital signal.
