How It Works

ATNJ 4G Band28 700MHz Home Mobile Signal Booster Repeater with LCD Display 7

Wireless network signals travel through the air as waves. The outdoor antenna receives strong signals and transmits them to the indoor booster. The booster amplifies the signal based on its frequency and emits the amplified signal through the indoor antenna, making it available for use.
