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.)
