1.1 Safety & Certification Notice
“Only qualified personnel should handle the DAS equipment. Any person involved in
installation or service of the DAS should understand and follow these safety guidelines.”
- Obey all general and regional safety regulations relating to work on high voltage installations,
as well as regulations covering correct use of tools and personal protective equipment.
- The power supply unit in repeaters contains dangerous voltage level, which can cause electric
shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to
be followed when servicing repeaters.
- To prevent electrical shock, switch the main power supply off prior to working with the DAS
System or Fiber BDA. Never install or use electrical equipment in a wet location or during a
lightning storm.
- When working with units outdoors, make sure to securely fasten the door or cover in an open
position to prevent the door from slamming shut in windy conditions.
- Use this unit only for the purpose specified by the manufacturer. Do not modify or fit any spare
parts that are not sold or recommended by the manufacturer. This could cause fires, electric
shock or other injuries.
- Do not operate this unit on or close to flammable materials, as the unit may reach high
temperatures due to power dissipation.
- Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or
abrasives on the DAS equipment. Alcohol may be used to clean fiber optic cabling ends and
connectors.
- Do not look into the ends of any optical fiber or directly into the optical transceiver of any
digital unit. Use an optical spectrum analyzer to verify active fibers. Place a protective cap
over any radiating transceiver or optical fiber connector to avoid the potential of radiation
exposure.
- Allow sufficient fiber length to permit routing without severe bends.
- For pluggable equipment, make sure to install the socket outlet near the equipment so that it
is easily accessible.

2.1 Overview
The N2ROU is a coverage system for in-building services delivering voice and data in high quality
and for seamlessly. As a distributed antenna system, it provides analog and digital phone
systems that are served in multiple bands through one antenna.
The system covers general public institutions and private facilities.
Shopping malls
Hotels
Campus areas
Airports
Clinics
Subways
Multi-use stadiums, convention centers, etc.
The system helps improve in-building radio environments in poor condition and make better
poor RSSI and Ec/Io. By providing communication services at every corner of buildings, the
system enables users to make a call at any site of buildings.
The system uses both analog (AMPS) and digital (TDMA, CDMA, WCDMA and LTE) methods.
The N2ROU system supports communication standards and public interface protocols in
worldwide use.
Frequencies: 600MHz, 700MHz , 800M , 1900MHz , 2100MHz , 2300WCS , 2.5TDD ,
2.5TDD_M, etc.
Voice protocols: AMPS,TDMA, CDMA,GSM,IDEN, etc.
Data protocols: EDGE,GPRS,WCDMA,CDMA2000,Paging, LTE etc.

Clustering multiple-buildings (campus) as one coverage
Option structures
Modular frequency upgrade
Multi-Band, Multi Operator
Signals with a plurality of service provider transmit simultaneously
Support multi-operator in a band
Low OPEX / CAPEX
Compact design
Upgradable design
Easy installation and maintenance
2.2 N2ROU
The N2ROU (New 2W Remote Optical Unit) is one of Alliance DAS series, and it supports 2W
output power for each band except 2.5TDD module. For 2.5TDD and 2.5TDD M modules, they
need 1.6W output power. The N2ROU has two types of multiplexers: one for supporting 5-band
and one for 7-band. Based on the required frequency, choose one of them for service.
(5-band Multiuplexer: 600 (RX Only), 700M, 800M, 1900M, 2100M, 2.5TDD)
(7-band Multiuplexer: 600 (RX Only), 700M, 800M, 1900M, 2100M, 2.5TDD, 2300WCS, 600M
(TX Only))
The N2ROU transports signals that multiple operators and multiple technologies are transmitted
simultaneously from BTS to a remote location over the same optical fiber. Furthermore, there is
reserved N2RDU slot to support 600LTE . And N2RDU slot is also can be replaced with the desired
frequency band.

N2ROU Component
The following figure shows internal configuration of the N2ROU fully equipped with frequency
bands.
Figure 3.5 –Internal View of Remote Unit
The N2ROU receives TX optical signals from Head-End and converts them into RF signals. The
converted RF signals are amplified through High Power Amp in a corresponding RDU, combined
with Multiplexer module and then radiated to the antenna port. RX signals received from the
antenna port are filtered through the multiplexer module, amplified at the RDU modules, and
converted into optical signals via optical module. After converted, the signals are sent to a upper
device of ODU or iODU. Four base bands are installed and additional three RDU modules can be
installed on the right side of the enclosure. Refer to the image above.
