Revision 2
1 Introduction
This document contains quick guidelines on how to operate the Bird DMR Repeater family and
how to install, commission and maintain a Repeater unit.
The DMR 604 Series is a medium power repeater in an IP65 enclosure. It was developed for use in
below ground environments but may also be used as a fixed multiband
and multi operator indoor coverage solution.
The DMR Repeater consists of an IP65 enclosure containing one channelized Radio Frequency Unit
(RFU), and a Power Supply Unit (PSU).
Standalone repeater applications can also be modified and used in the fiber DAS systems where base
stations are not available for signal feeding to the system.
2 DMR Operational Description
The DMR 604 repeater series is a wall mounted medium power radio repeater. It can operate in the
stand-alone applications as well in the fiber fed DAS systems where the repeaters are used for off air
feeding of the DAS network where Base stations are not available.
DMR604 Repeater unit series is for the 462.4125 and 467.4125 MHz band. The system consists of
following parts:
• Power supply Unit (PSU)
• Internal Duplex Filters (DPX) filtering Uplink and Downlink frequencies and necessary RF
combiners depending on the Remote Unit configuration.
• Band selecting Repeater board.
• Optional- Remote Gateway unit (called RGW) used for remote access/configuration and alarm
supervision
The User can set the following parameters in the Repeater unit via web-based GUI application:
• Gain Values (UL & DL)
• Bandwidth (UL&DL)
• ALC threshold (UL & DL)
• Self-oscillation protection
• Gain Link Symmetry-Gain trail (UL&DL)
