SECTION 2

2.1 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 is
inadequate for 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 .

SECTION 3

3.1 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 100-240 VAC mains
supply. A standard length of 10 mtr 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.

4.1 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.

5.1 Installing the HB-20

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.

5.2 Installation Tools

You will only need the standard wrenches/hammer/screwdrivers/pliers set
for installing the HB-20 booster and donor antenna.

5.3 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.

5.4 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.

3. Alarm indication LED will glow red colour, after inserting all the attenuation

the output power is greater than the desired level ( 10dBm ) the system will

Shutdown the PA for 30 seconds and restart .

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 100~240VAC

3 Verify the D.C Adapter output voltage is 9V.

B. Signals are not

amplified after
completing the
installation

2. Check all the connectors of the booster 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.

3. The poor isolation between donor and server
antenna will cause system oscillation and it may
damage the amplifier of the booster. It is to note

that the booster 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 booster
installation or site survey. If so, adjust the gain of
booster 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 booster is high. If
alarm persists for a long time contact SHYAM
