“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.
‐ The power supply unit in repeaters contains dangerous voltage levels 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.
‐ The repeater cover (door) should be securely fastened in open position(with a cord), during
outdoor work in order to prevent door from slamming due to wind (which could cause bodily
harm or damage).
‐ Use this unit only for the purpose specified by the manufacturer. Do not carry out any modifications
or replace any parts which are not sold or recommended by the manufacturer. This could cause
fire, electric shock or other injuries.
‐ Repeaters generate radio signals and thereby give rise to electromagnetic fields that may be
hazardous to any person in the immediate proximity of the repeater and the repeater antennas
for an extended period of time.
‐ Due to power dissipation, this repeater may reach a very high temperature. Do not operate this unit
on or close to flammable materials.
‐ Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives.
‐ Signal booster warning label message should include (Class B Industrial Booster)

‐ 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.

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.
The system enhances in‐building radio environments that lack signal quality by improving the RSSI
and Ec/Io. By providing communication services throughout the building, the system enables users to
make a calls anywhere in the coverage area.
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 comprises frequency specific modules. Coverage for a specific frequency band is
accomplished by inserting a corresponding frequency module into each unit. Because it delivers
multiple signals with one strand of single mode fiber, the system, requires no additional hardware
modifications whenever a new frequency is added.
The system is featured with the following:


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

18/117
SC‐DAS
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.

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.
Up to four ODUs can be connected with BIU each SISO and MIMO path

1) Donor Optic Unit (DOU)
The DOU performs the RF to optical conversion of TX signals as well as the optical to RF conversion
of RX signals.
Using an optical splitter, this unit divides optical signals from a Laser Diode into four and then
distributes them to each optical port. With a total of four Photo Diodes in RX, the DOU performs the
optical to RF conversion of signals received from each optical port. In addition, the unit is equipped
with an ATT to compensate for optical loss in the fiber or fiber connectors.
Since is uses a WDM, it uses only one strand of fiber for each ROU it connects to.
With internal FSK modem, it will allow operation from a remote site.
