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 and WCDMA) 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, 2500_100TDD, 2500_FB_TDD etc.
 Voice protocols: AMPS,TDMA, CDMA,GSM,IDEN, etc.
 Data protocols: EDGE,GPRS,WCDMA,CDMA2000,Paging, LTE etc.
The N2ROU is equipped with 4-band (700M, 800M, 1900M, 2100M) module by default. 600L,
2300WCS, 2.5TDD, 2500_100TDD, 2.5TDD_M and 2500_FB_TDD are available for service, but
only two of them can be installed with the default module as optional frequency bands. 600L is
not ready at this stage and will be developed later. When 600L is available for service, a
maximum of three optional bands can be installed. As it delivers multiple signals with one optical
cable, the system, in one-body type, does not require additional facilities whenever new
