A Cell Phone Repeater is a device that is designed to receive a cell phone signal from one of the carriers, amplify the signal and then retransmit the signal to another repeater or to broadcast the signal into an area were the signal is weak and customers routinely have difficulty in making and receiving calls. The carriers employ many cell phone repeaters in their business, however they are unable to deal with every case of poor signal due to the shear magnitude of the problem, limited funds and a continuously changing environment.

Buildings and other manmade objects tend to weaken the signal and as you become further and further away from the tower, your signal is weaker still. Customers may notice that they have better reception in different parts of their homes or even outside of their homes or businesses. One of the solutions to a weak signal and hence poor cell phone reception is to install a cell phone repeater. The mobile carriers install large capacity repeaters, however if you do not want to wait until they get around to improving the signal strength in your area, an option is to install a residential or business cell phone repeater yourself that will operate in your immediate area.
