説明
A cell phone signal booster (also known as amplifier or repeater) is made up of three main elements – exterior antenna, amplifier, and interior antenna. They form a wireless system to boost cellular reception.
The main aim of the cellular phone signal booster is taking the existing cell phone signal around your car, office, workstation, or home and amplifying it. After amplification, the signal is rebroadcasted to the area with no reception or weak signal. Apart from consisting of an amplifier to boost the reception, external antenna, and internal antenna, there’re cell phone boosters with indoor antenna and amplifier as a single unit making them superb indoor cell phone signal boosters. In most cases, the three components are detached. Other optional components include the Attenuator (reduces unwanted frequency signals), Lightning Surge Protector, Splitter, and Tap.
