Confidential & Proprietary 11/116 SC-DAS Section2 System Overview 2.1 General overview 2.2 System overview Confidential & Proprietary 12/116 SC-DAS 2.1 General overview SC-DAS 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 SC-DAS system supports communication standards and public interface protocols in worldwide use. Frequencies: VHF,UHF, 700MHz, 800MHz,850MHz 900MHz,1900MHz,2100MHz, etc. Voice protocols: AMPS,TDMA, CDMA,GSM,IDEN, etc. Data protocols: EDGE,GPRS,WCDMA,CDMA2000,Paging,LTE, etc. SC-DAS is in modular structure per frequency. To provide desired frequency in a building, all you need to do is to insert a corresponding frequency module into each unit. As it delivers multiple signals with one optical strand cable, the system, in one-body type, does not require additional facilities whenever new frequency is added. The system is featured with the following: Flexibiltiy & Scalabiltiy Support fiber-optic ports up to 32 or 60(using OEU) Clustering multiple-buildings (campus) as one coverage Modular structures Modular frequency upgrade Plug-in type module Multi-Band, Single operator Confidential & Proprietary 13/116 SC-DAS z Signals with a plurality of service provider transmit simultaneously Support multi-operator in a band(Max 2operator) Low OPEX / CAPEX Compact design Upgradable design Easy installation and maintenance Adopt auto ID scheme SC-DAS platform will serve two primary segments; the first will be as a carrier deployed coverage enhancement product for their frequencies only and the second is as a low cost public safety and single carrier combination product. Confidential & Proprietary 14/116 SC-DAS 2.2 System overview SC-DAS is composed of devices given below. Basically, the system consists of BIU (BTS Interfcace Unit), ODU (Optic distribution Unit) and ROU (Remote Optic Unit). For addition of more ROUs, it has OEU (Optic Expansion Unit). BIU has two layer which supports both SISO and MIMO configuration using separate optical fiber cable. Fig2.1 shows basic system topology for SISO Figure 2.1 – Basic system topology supporting SISO configuration Confidential & Proprietary 15/116 SC-DAS Figure 2.2 – Basic system topology supporting MIMO configuration As shown at Fig2.1 and 2.2, one optical cable needs for SISO configuration but two optical cable needs for MIMO cofiguration when it connected with ROU. A site requirement for a SISO application even though more optical cable needs, we can expand more ROUs using MIMO slot up to 64 ROUs Without addtive BIU for expanding MIMO, it supports both SISO and MIMO configuration usign one BIU. For configuration of MIMO, it needs ODUs for MIMO path only.
