2. Disclaimer

Every attempt has been made to make this material complete, accurate, and
up-to-date. Users are cautioned, however, that Shyam Telecom Limited
reserves the right to make changes without notice and shall not be responsible for any damages including consequential, caused by reliance of the contents presented, including, but not limited to, typographical, arithmetical, or listing errors.
Product name(s) referenced in this document may be trademarks or registered trademarks of their respective companies, and are hereby acknowledged.
In areas with unstable power grids (mains) all repeaters must be installed with a voltage regulator ensuring a constant voltage level at the repeater power input. A maximum voltage deviation should remain within the input range to the repeaters for warranty purposes.
All antennas must be installed with lighting protection. Damage to internal modules, as a result of lightning is not covered in the warranty.

3. Safety Instructions and Warnings

3.1. Personnel Safety

Before installing or replacing any equipment, the entire manual should be read and understood. The user needs to supply the appropriate AC power to the Repeater. Incorrect AC power settings can damage the repeater and may cause injury to the user.
Next Generation Signal Enhancement
Throughout this manual, there are "Caution" warnings, "Caution" calls
attention to a procedure or practice, which, if ignored, may result in injury or damage to the system or system component or even the user. Do not perform any procedure preceded by a "Caution" until the described conditions are fully understood and met.

3.2. Equipment Safety

When installing, replacing or using this product, observe all safety precautions during handling and operation. Failure to comply with the following general safety precautions and with specific precautions described elsewhere in this manual violates the safety standards of the design,
manufacture, and intended use of this product. Shyam Telecom Limited
assumes no liability for the customer's failure to comply with these precautions. This entire manual should be read and understood before operating or maintaining the repeater system.

CAUTION
Calls attention to a procedure or practice which, if not followed, may result in
personal injury, damage to the system or damage to individual components. Do not perform any procedure preceded by a
CAUTION until described conditions are fully understood and met.
WARNING! This equipment complies with FCC & IC radiation exposure limits
set forth for an uncontrolled environment. This transmitter must not be co­located or operating in conjunction with any other antenna or transmitter. The unit with server antenna must be installed to provide minimum 110 cm separation distance between the server antenna and the body of user or near by person. The donor antenna used for this transmitter must be fixed­mounted on outdoor permanent structures with a separation distance of at least 1.5 meters from all persons during normal operation.
The RF electric performance of the repeater conforms to FCC requirement of the inter modulation and spurious emission. It avoids interference problems.

3.3. Electrostatic Sensitivity

CAUTION
ESD = ELECTROSTATIC DISCHARGE SENSITIVE DEVICE
Observe electrostatic precautionary procedures.
Semiconductor transmitters and receivers provide highly reliable performance when operated in conformity with the intentions of their design. However, a semiconductor may be damaged by an electrostatic charge inadvertently imposed by careless handling.
Static electricity can be conducted to the semiconductor chip from the centre pin of the RF input connector, and through the AC connector pins. When
unpacking and otherwise handling the Repeater, follow ESD precautionary
procedures including the use of grounded wrist straps, grounded workbench surfaces, and grounded floor mats.

4.5. General

Mobile Communications Systems are planned as cellular systems and each cell of the base station is required to provide RF coverage over a certain geographical area as per defined RF power levels. Due to the RF propagation properties, even using high radiated RF powers or complicated antenna systems, there are zones within the coverage area where the RF signal strength from base station remains inadequate for establishing the desired connectivity to mobile users.
Repeaters traditionally are deployed in the Mobile Communication network to fill in the “Dead Zones” caused by blocking of signals by geographic topologies such as mountains, valleys, dense foliage, high rising urban landscapes and other man-made structures. The distance from the base station also adversely affects the RF signal strength. The user views repeaters as a means to extend base station coverage so as to reduce the number of base stations and thereby accelerate network availability.
Repeater systems are installed after meticulous planning between BTSs and the mobile users to provide RF coverage in the shadowed regions. Repeater
systems are available for different applications and ultimate choice shall
depend on some of the factors mentioned below:
Area to be provided with coverage.
Indoor/outdoor coverage.
Availability of BTSs in the vicinity.
Antenna isolation to be achieved.

5. Functional Description Of DB5R Dual Band Repeater

5.1. General Description

The DB5R Dual Band Repeater System is designed to provide outdoor
coverage and can handle signals in up to five sub bands with 3+2 configuration (maximum) in two of the service bands, used around the World by various service operators. It provides highly selective amplification in the pre-set frequency bands. The details of operating service frequency bands are given below:
S.NO. Service Band DL Frequency (MHz) UL Frequency (MHz)
1. SMR 800
2. Cellular
3. SMR 900
4. EGSM
5. GSM 900
6. DCS
7. PCS
8. UMTS

1930-1990 1850-1910
2110-2170 1920-1980
The Customer is requested to refer to the packing list giving the details of frequency band set & the bandwidths of different sub bands equipped in the repeater (FCC & IC applications only apply for Cellular & PCS band operations).
The DB5R repeater is designed to provide optimal coverage, the area
covered shall primarily depend on RF power radiated, manmade structures in the area (high rise buildings), the geographical topologies and availability of reflecting surfaces.
The ultimate performance & coverage shall depend on the obstructions
blocking/absorbing of the RF signals by various objects between the Server antenna of RF repeater and the mobile users.
The repeater is specifically designed for the Operators who are
allocated frequency spectrum in different service bands and non­contiguous sub bands are specified.
The repeater adopts duplex mode and bi-directional amplification for
U/L & D/L signals between the base station and mobile users.
It receives signals from the BTS through a DONOR antenna (highly
directional outdoor antenna) and distributes the signals to mobile users
after amplification through a set of SERVER antennas (omni/patch
directional) system in the D/L.

Next Generation Signal Enhancement
In the U/L, the signals from the mobile users are picked up by
SERVER antenna and retransmitted to the BTS after amplification.
The repeater finds applications in tunnels, highways, large size
airports, and open market areas etc. where traffic requirement is high.
The system can be incorporated with optional Remote Management
System (RMS) which can be used for configuration and monitoring the
status of the link. It helps not only speedy maintenance but remote
configuration also through wireless modem.
The repeater consists of the following modules/units:
LNA
Converter modules
Power amplifiers
Power supply module
Duplexer filters for transmit/receive directions
Supervisory module
Diplexer Unit for segregating bands
A metallic case houses the repeater. Arrangement is made for heat
dissipation especially for amplifiers, which generate more heat. The choice of suitable metal as the case material gives a lightweight design with good heat conduction and waterproof protection. The housing conforms to IP65 (NEMA 5) standards.
