Mobile Signal Booster
A cell phone signal booster (also known as amplifier or repeater)
is made up of three main elements - exterior antenna, amplifier,
and interior antenna. They form a wireless system to boost cellular
reception.
A cell phone reception booster is generally a repeater system that
involves the amplifier adding gain or power to the reception
in various directions. Even for a cheap cell phone signal booster, maximum gain differs by application. The work of an outside
antenna is to both receive and transmit signals
