System, a device and a method for adjusting signal strength in a distributed amplifier system
The invention discloses a system comprising a first device and a plurality of second device. The system comprises a first device and a plurality of second devices. The first device comprises a receiver, a spectrum analyzer, a controller and a transmitter. The receiver receives, from at least one antenna, a plurality of signals with different signal strengths from different sources. The spectrum analyzer is communicatively coupled to the receiver and obtains strengths of the plurality of received signals. The controller is communicatively coupled to the spectrum analyzer and adjusts a radiation feature of one of at least one antenna to minimize a difference of the strengths between a plurality of received signals after adjustment. The transmitter transmits the received signals after adjustment to a plurality of second devices distributed within a site. The plurality of second devices transmit the plurality of received signals after adjustment within the site.
1. A system comprising:
a first device comprising
a receiver configured to receive, from at least one antenna, a plurality of signals with different signal strengths from different sources;
a spectrum analyzer communicatively coupled to the receiver and configured to obtain strengths of the plurality of received signals;
a controller communicatively coupled to the spectrum analyzer and configured to adjust a radiation feature of one of at least one antenna to minimize a difference of the strengths between a plurality of received signals after adjustment, the radiation feature including location of at least one antenna; and
a transmitter configured to transmit the received signals after adjustment to a plurality of second devices distributed within a site; and
the plurality of second devices configured to transmit the plurality of received signals after adjustment within the site.
