The signal booster also works in the other direction. The signal amplifier is specially designed to amplify only the cellular frequencies that the 2G, 3G and 4G LTE networks run on, and then pass that signal to an inside antenna, which broadcasts the strong cell signal to the inside of the building or vehicle. A high powered antenna outside of the building or vehicle receives the existing cell signal and passes it over a low loss cable to a signal amplifier. There is no magic in how a cell phone booster works. Unlike the signal booster apps and stickers from the past, cell phone signal boosters (also known as cell phone repeaters or cell phone amplifiers) have been tested and proven to work by the Federal Communications Commission (FCC). Do Cell Phone Signal Boosters Really Work? In fact, there are millions of cell phone signal boosters currently operating in the United States as we speak, even though most people have not even heard of the term. They use powerful signal amplifiers, high gain antennas, and low signal loss cable to amplify the existing outside signal and broadcast it inside a building or vehicle.Īll cell phone signal boosters on the market today have also been certified and approved by both the FCC and the major carriers, including Verizon, AT&T, T-Mobile and Sprint, as well as the other major carriers in North America.
