Communication Systems
The RF electric performance of the HB-20 booster conforms to ETSI
requirement of the inter modulation and spurious emission. It avoids the
interference problem.
3.0 Introduction: Booster Theory / Background
In mobile cellular communication system, boosters provide the radio frequency
(RF) coverage to areas, which either lack signal, or the required signal strength
for adequate mobile phone performance. To the typical user, this translates to the
inability to place or receive mobile phone calls in or out of the area, and in most
cases will result in a dropped call while entering into the poor coverage area.
Insufficient wireless coverage can occur both indoors and outdoors, and may
include indoor areas such as office buildings, parking garages, apartment
buildings, shopping malls, and residential homes. Outdoor areas are degraded by
geographic topologies such as mountains, valleys, dense foliage and high rising
urban landscapes which can easily degrade or obstruct the cell site’s signal from
the mobile phone.
The weak coverage problem can be solved by installing an active booster
system, designed for use in a multitude of installation configurations. Booster
systems provide an effective solution by redirecting, filtering and amplifying the
available signal at the donor antenna, into the weak coverage area, through a
properly selected interior coverage antenna. The illumination of the weak
coverage area allows the user’s handset to operate as intended within the
building or weak coverage area, while maintaining the user’s call clarity and
quality, which reduces service complaints and potential subscriber churn.

4.0 Description of HB-20 Booster installation Kit
The HB-20 booster system contains an automatic power control, bi-directional
amplifier (BDA) supplied along with a donor antenna (highly directive outdoor
antenna) and server antenna (indoor omni directional antenna), specifically
designed for interior configurations. The donor antenna must be pointed toward
the cell of the base station from where the signal is to be picked up and is usually
mounted on the exterior of the building so as to receive the maximum forward
signal level from the base station. The indoor antenna of HB-20 booster provides
RF signal in all directions downward and outward from the installation point.. A
adopter is supplied with HB-20, powered by universal 90/240 VAC mains supply.
A standard length of 7 mm RF coaxial cable with connectors is supplied to
connect the donor antenna and HB-20 booster. Any other RF coaxial cable length
is also available optionally, on request.

5.0 System Design and Setup
The HB-20 is designed to provide optimal coverage for areas of 500 Sq Meters
(5,000 sq. ft) to 1,000 Sq Meters (10,000 sq. ft). However, performance also
depends on the amount of in-building shadowing, and the available forward
signal level at the donor antenna. Typical coverage is usually planned for
relatively small areas such as large conference room or several adjacent rooms
in smaller office areas. Indoor coverage varies greatly due to the nature of
various building construction techniques and materials.
The system design is quite simple & straightforward. The signal from the base
station (of the selected Operator) is picked up, preferably on the rooftop.
The built in receive signal level indicator in HB-20 booster helps in aligning the
donor antenna towards the selected base station & it always shows the received
signal level from the base station. It is imperative to monitor the received signal
level from the base station, also called downlink signal. Downlink signal may
change if some high building, trees or any other obstruction comes in the way of
line of site (LOS) between the BTS & the Donor antenna. This may reduce the
downlink received signal level & will result in poor service.
6.0 Installing the HB-20
6.1 Pre-installation considerations
1. Once the expected coverage area is determined, identify the installation
location for the donor antenna and HB-20 booster. Ensure that the donor
antenna has a direct line-of-site to the service provider’s base station.
2. HB-20 installation site location criterion
i. A cool, dry location, away from other heat generating appliances or
equipment.
ii. Accessibility to electric power point.
iii. Flat, structural mounting surface.
iv. Accommodation for the indoor antenna providing line-of-site coverage to
as much of the coverage area as possible.
6.2 Installation Tools
You will only need the standard wrenches/hammer/screwdrivers/pliers set
for installing the HB-20 booster and donor antenna.

6.3 Installation Procedure: Do It Yourself
To install HB-20 booster, follow the steps as mentioned below:
1. Locate weak signal areas by moving around with a mobile phone and the
SIM card of the cellular operator, and check the signal level indicated by
the number of bars on the mobile phone display.
2. Similarly, locate donor (outdoor) antenna position by observing the
maximum signal received from the base station.
3. Unpack the equipment supplied and check as per the packing list.
4 Mount the donor (outdoor) antenna at the position selected (ref 2 above).
5 Mount the HB-20 booster in the area of weak signal (ref 1 above)
6 Route the RF coaxial cable and interconnect it with the donor
antenna and HB-20 booster, which is supplied in the installation kit.
7 Ensure that the three-pin power point has proper earthing
connection, before switching on the power to booster.
Please remember the following important points:
i. The RF cable must not be kinked, cut or damaged in any way.
ii. Connect the RF cable to the donor antenna taking care to avoid cross
threading or stripping. The RF connections should be snug and tight.
iii. Seal the outdoor connectors with waterproof sealant (such as M–
seal) or the appropriate weather tight boot.
6.4 Power Startup / Alarm Checks / Coverage Testing
1. Plug in the AC/DC Power Adapter power cord to AC main and other side
DC plug insert 9V DC socket in Home Booster.
2. When the booster is ON initially all the LED’s will blink two times.
3. The system will automatically control the attenuation to keep the both uplink
and downlink output power at a constant level of 10dBm. The system will
insert or release the attenuation by 1dB step.

Annexure 2
Trouble shooting procedure HB-20
Conditions Possible Reasons & Solutions
A. Initially all the LED’s
will blink two times
1 Check the power cord and the AC power socket
2 Please note that the AC main power has to be within the
range 90~240VAC
3 Verify the D.C Adapter output voltage is 9V.
B. Signals are not
amplified after
completing the
installation
1. Check all the connectors of the repeater system for proper
connections. The “BTS” connector has to be connected to
donor antenna, and the “MS” connector has to be
connected to server antenna.
2. The poor isolation between donor and server antenna will
cause system oscillation and it may damage the amplifier of
the repeater. It is to note that the repeater gain should
be at least 10 db lower than the antenna isolation.
C. The system performed
well in the beginning
but after few days the
performance has
degraded.
1. The received signal level from the base station might have
degraded due to environmental changes such as new
building construction and so on. If so, please follow the
suggestions below:
a. Try to re-align the donor antenna towards the base
station
b. Adjust the gain attenuation of the Up or Down link
direction
c. Relocate the donor antenna to solve the problem
2. RF Cable problem: Check the RF cable for physical
damage by rats etc. Also check for sharp bands or RF cable
pressed. Under these conditions, RF signal losses could
have increased. If so, replace RF cable.
3. Indoor structural change: The signal level will vary
according to the interiors. Look for any interior changes
subsequent to the repeater installation or site survey. If so,
adjust the gain of repeater or re-align the server antenna
without affecting the existing coverage.
D. Alarm indication LED
will glow in red colour.
It indicates that the received signal level from BTS is high or
forward / reverse gain of repeater is high. If alarm persists for a
long time contact SHYAM technical support team.
