Signal booster warning label message CAUTION DOUBLE POLE/NEUTRAL FUSING Confidential & Proprietary 6/49 Section2 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 Confidential & Proprietary 7/49 frequency is added. The system is featured with the following:
Flexibility & Scalability Support fiber-optic ports up to 60 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 in the future. And N2RDU slot is also can be replaced with the desired frequency band.

Confidential & Proprietary 12/49 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.

Confidential & Proprietary 44/49 Figure 4.27 Priliminary Work for Installing AOR The procedures are 1. Remove the dummy cover from the port that is used for connecting AOR. 2. The location of ports that need to be removed can be found in the figure No. 2 (The ports are circled in red.). Use the same method of No. 1 to remove the dummy cover. 3. Install the inner I/O cable with the screws included in the package. Pay special attention to the direction of connector when intalling them. 4. Connect the inner I/O cable to the defined connector of the RCPU. 5. Install two inner RF cables with the screws included in the package. 6. Check the names of the ports. Match and connect the external port with the correct R-
OPTIC port. Confidential & Proprietary 45/49 The following figure shows the diagrm connecting N2ROU with AOR. Refer to the figure below for cabling after the preliminary work. For legacy BIUand eBIU do not need this preliminary work, but for the new version, the preliminary work is required in order to connect AOR. For connecting AOR with the N2ROU, pay attention to the cable length. The cable length between the N2ROU and AOR is 1.5m.

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC PART 15.21 STATEMENT Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. RF RADIATION EXPOSURE This equipment complies with RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 150 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. RF exposure will be addressed at time of installation and the use of higher gain antennas require larger separation distances. (Max. antenna gain: DL 17 dBi) Confidential & Proprietary 49/49
