Cell phone signal amplifier (also referred to as signal booster or direct signal amplifying station) is designed to solve cell phone signal blind. In some location such as remote area from base station, high-rise, basement, location behind by building, underground civil air defense projects, subway stations, elevator and many other places, cell phone can not be used due to receiving signals fail. This cell phone signal amplifier is aimed to solve the problems.

Signal coverage area :
|1.Support Maximum coverage area is 2000 square meters.
( Depend on the area condition)2.One indoor antenna only use for about 50-200 square meters in open space.(The indoor and outdoor antenna quality depends on the indoor signal coverage area.）3.If want to make all use of 2000 square meters which the host supports,
need to add more indoor antennas and power divider / splitter.
