Section1 Safety & Certification Notice Confidential & Proprietary 12/117 SC‐DAS
“Only qualified personnel are allowed to handle this unit. Read and obey all the warning labels attached in this user manual” Any personnel involved in installation, operation or service of the SOLiD Technology repeaters must understand and obey the following: ‐ Obey all general and regional installation and safety regulations relating to work on high voltage installations, as well as regulations covering correct use of tools and personal protective equipment.
‐ Any DAS system or Fiber BDA will generate radio (RF) signals and continuously emit RF energy. Avoid prolonged exposure to the antennas. SOLiD recommends maintaining a 34.0cm (13.4 inches) minimum clearance from the antenna while the system is operating.
Section2 System Overview 2.1 General overview 2.
2.1 General overview SC‐DAS platform is a coverage system for in‐building services delivering seamless, high quality voice and data As a distributed antenna system, it provides analog and digital phone services in multiple bands through one antenna. The system covers public and private venues such as: Shopping malls Hotels Campus areas Airports Clinics Subways Multi‐use stadiums, convention centers, etc.
Support multi‐operator in a band(Max. 2 operator) Low OPEX / CAPEX Compact design Upgradable design Easy installation and maintenance Adopts auto ID scheme The SC‐DAS platform will serve two primary segments; first as a carrier deployed coverage enhancement product for their specific frequencies and second as a low cost, public safety / single carrier product.
2.2 System overview SC‐DAS comprises the components listed below. The base system consists of a BIU (BTS Interfcace Unit), an ODU (Optic distribution Unit) and a ROU (Remote Optic Unit). For use with multiple ROU’s, it has OEU (Optic Expansion Unit). The BIU has two layer which support both SISO and MIMO configuration using separate optical fiber cable. Fig2.1 shows basic system topology for SISO Figure 1.1 – Basic system topology supporting SISO configuration Figure 2.
As shown at Fig.’s 2.1 and 2.2, one strand of fiber is needed for SISO configuration but two strands are needed for MIMO cofiguration when connected with an ROU. Applications requiring up to 32ROU’s for SISO are possible with one BIU. Each SISO ROU will require an additional strand of fiber and an additional 32 ROU’s can be added to the same system for MIMO applications. MIMO requires 2 strands of fiber per ROU as well as MIMO specific ODU’s.
To reduce number of optical cables between multi‐building applications, we can utilize the OEU(Optical Expansion Unit) Fig 2.3 shows expansion system topology supporting SISO configuration using OEUs Figure 2.3 – Expansion system topology supporting SISO configuration Figure 2.4 – Expansion system topology supporting MIMO configuration Fig 2.

4.2 ODU (Optic distribution Unit) ODU receives TX RF signals from upper BIU and converts them into optical signals. The optical signals are sent to ROU through optical cables. This unit converts optical signals from ROU into RF signals and sends the converted signals to BIU. For each shelf of the ODU, up to two DOUs (Donor Optic Unit) can be installed in it. One DOU is supported with four optical ports. Therefore, one ODU can be connected with eight ROUs.
