Dynamic gain adjustment via mechanical transducers involving active combiners in wireless networks

A system for adjusting gain when combining signals from radio heads, comprising:

• two or more radio heads connected to an evolved node B (eNodeB) operate to provide signals to an amplification system;
• the amplification system operates with an active combiner and an amplifier;
• the active combiner operates to combine signals of the two or more radio heads and provide an output of the combined signals;
• the active combiner receives an instruction from a member of the two or more radio heads to change a gain in the amplifier, wherein the instruction is received over an antenna interface standard group (AISG) protocol;
• and
• the amplifier operates a motor that moves a magnetic core through a solenoid to change a current, wherein a first change in the current causes a second change in the gain, wherein the second change increases or decreases a power level.

A system for dynamically changing gain, comprising:

• a radio frequency (RF) amplification system receives a gain change notification message from a controlling RF source;
• a motor in a power distribution circuit of an amplifier in the RF amplification system operates on a receipt of the gain change notification message, wherein the amplifier is a bi-directional amplifier;
• the motor moves a magnetic core through a solenoid in a transducer in the amplifier;
• a movement of the magnetic core changes a current in the solenoid;
• and
• a power level in the transducer changes to increase or decrease the gain.
