How Cell Phone Repeaters Work？

Cell phone repeaters, also known as cell amplifiers, cell extenders or cell boosters, are fairly simple to use.  Most boosters consist of three major components: an external directional antenna, an internal antenna and a signal amplifier.Cell phone repeaters
The external directional antenna is typically placed outside the home or office (preferably outside a window or on a roof) and is positioned to face the nearest cell tower. In the event that you are installing the antenna yourself, a signal strength monitor is recommended to help you figure out the best location for the antenna. The external directional antenna is designed to pick up the weak signal that is being broadcast by your cellular provider.
The signal the external antenna picks up is sent over wires to the signal amplifier. The signal amplifier is what increases the signal. Your boosted signal is then sent to the internal antenna which wirelessly rebroadcasts a more powerful signal within your space.
