what is gsm booster

A GSM booster, also known as a cell phone signal booster or cell phone signal amplifier, is a type of bi-directional amplifier used to improve cell phone reception. It is a set of equipment that helps the client receive a better signal when it is lacking within their building, vehicle, or remote location. A cellular booster amplifies a cellular signal within a given area to achieve faster data speed and a more comprehensive range of coverage with fewer drops. The booster works by pulling in weak signal, boosting it, and then rebroadcasting it inside the area in need. The system typically consists of an exterior antenna, amplifier, and interior antenna. The outside antenna receives and transmits signals from nearby cell towers, while the interior antenna rebroadcasts the amplified signals to the area with no reception or weak signal. It is important to note that a cell phone reception booster will not work if there is no signal available, and for a signal booster to work, there must be at least one bar of coverage.
