System, a device and a method for adjusting signal strength in a distributed amplifier system

A 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 first receiver and configured to determine whether the strengths of the plurality of received signals are within a predetermined range;
• and
• a controller communicatively coupled to the first spectrum analyzer and configured to adjust a radiation feature of some or all of at least one antenna such that the strengths of the plurality of received signals are within the predetermined range.

A device comprising:

• a receiver configured to receive, from at least one antenna communicatively coupled to the device, 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 are within a predetermined range;
• a controller communicatively coupled to the spectrum analyzer and configured to determine an adjustment indication according to the strength;
• wherein the device further comprises a filter configured to adjust some or all of the gain of at least one of the strengths of the plurality of received signals according the adjustment indication such that the strengths of the plurality of received signals after adjustment are within the predetermined range.

A method comprising:

• receiving, from at least one antenna, a plurality of signals with different signal strengths from different sources;
• determining whether the strengths of the plurality of received signals are within a predetermined range;
• and
• adjusting gain of some or all of at least one of the strengths of the plurality of received signals such that the strengths of the plurality of received signals after adjustment are within the predetermined range.
