Kingtone Bi-Directional Amplifiers system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Bi-Directional Amplifiers system is to receive low-power signal from BTS via radio frequency transmission nd then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.
