Abstract

A system and method for substantially reducing oscillation produced by a network amplifier. An exemplary method includes receiving a cellular signal at a first antenna of a network amplifier and applying a first amplification factor to the cellular signal. The resultant amplified cellular signal is transmitted to a target destination via a second antenna. A first signal level of the cellular signal is measured while the first amplification factor is being applied to the cellular signal. Then, a second amplification factor that is less than the first amplification factor is applied to the cellular signal, during which a second signal level of the cellular signal is measured. If the second signal level is significantly less than the first signal level, the first amplification factor is reduced by a predetermined amount.
