    Kingtone Repeaters 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 Repeaters  system  is  to  receive  low‐ power  signal  from  BTS  via  radio  frequency transmission  and  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.
