3 System Description

3.1 Purpose

The DAS system is intended to distribute wireless services for voice and data over dedicated

fiber from Master units located at the BTS site hotels to small Remote units intended for

discrete mounting in an urban or suburban environment on poles or other outdoor

locations. The system is built on multiple wideband RF links both uplink and downlink

running on a separate fibers between the BTS site and Remote unit using multi drop for best

fiber usage and CWDM technology.

3.2 General

The system has either a common optical cable for its signal paths (uplink and downlink) or

separate optical cables, all units are equipped with remote control and the communication is

performed via a sub-carrier channel on each optical link. Every remote unit has a WEB

interface that is accessible from a standard PC with a WEB browser. In the master unit there

are low power TX and Rx RF cables connection from the various BTS’s to the optical interface

through some splitters. The system is managed by a CGW, Central Gateway that is the

overall interface point of the system for management function.

The CGW can interface to top level O&M systems, it has routing and firewall functionality

alarm log and access control for the complete DAS system. It has the function to

interconnect all control communication, monitor the modules in of the DAS system and send

alarms to a common point via Email and/or SMS.
