INTRODUCTION AND REASONS FOR WEAK

CELLULAR SIGNALS

Cell Phone Signal Booster is a perfect solution for providing improvement of cellular signal reception inside
a house, office, restaurant, VIP Room, apartment, building or shopping mall.

Generally cell phones cannot pick up or maintain a strong cellular signal due to one of the two following
reasons:

1.

Location of the Nearest Base Station

– Base stations are used to provide broad coverage. However

there are many areas in which signal strength gets reduced due to topographic peculiarities or local
Governmental restrictions regarding the height or location of base stations. Rural areas generally have
fewer base stations than urban regions.

2.

Natural and Man-Made Obstructions

– Signal strength can also be negatively affected by trees, hills,

buildings, weather and other obstructions. You may be relatively close to a base station but still unable to
make a call. This often occurs inside houses, offices and other buildings with stucco, concrete or metal
walls that may block the signal.

The Signal Booster works with two antennas. An Indoor antenna communicates with your cell phone and
an Outdoor antenna communicates with the base station (BS). The Outdoor antenna receives a signal from
the BS and sends it through the cable to the Signal Booster, where it gets amplified and re-transmitted by
the Indoor antenna throughout a building. When the Indoor antenna picks up a signal from your cellular
device, the Signal Booster amplifies that signal and transmits it through the cable to the Outdoor antenna
and back to the BS.

(Note: The Signal Booster will only operate if there is an adequate signal to amplify.)
