Description

A cell phone signal booster is a system made up of antennas, cable and a signal amplifier that takes an existing cell signal, typically found outside your home, business or vehicle, amplifies the signal and then broadcasts it to an inside area that has a weak or no signal. In order for the system to work, there must be an existing, stable outside signal for the system to receive and amplify. Signal boosters are unfortunately not able to create signal by themselves, they only amplify and transmit cell phone signal, so if you are not able to place an external antenna in a location that has an existing signal, then a cell phone signal booster will not work for you. How does a Signal Booster Work? The general way that a cell phone signal booster for a home or business works is the outside antenna is mounted at or above the roofline of the building, in a location where it can pick up the strongest existing outside cell signal. The cell signal is received by the antenna and is sent over a cable into the building, where it is received by the signal amplifier. The amplifier boosts the cell signal significantly, and then sends it over another cable to one or many inside antennas, which broadcast the improved signal to the area where each antenna is located. The entire process also works in reverse, so you get a strong and reliable connection back to your carrier.
