An adaptive electromagnetic interference (EMI) detection and reduction device for multi-port applications is provided. The invention includes at least two physical devices (PHY), where the PHYs transmit data along wire pairs to a register jack (RJ). The transmissions create EMI along the wire pairs, where the transmissions have constructively interfering resonant frequencies having phases and amplitudes. An antenna is disposed proximal to each RJ, where the antennae detect each frequency. A resonating network determines a peak amplitude of each frequency, an envelope detector amplifies each peak amplitude from the resonating network. A discretization circuit converts the amplified peak to discrete amplitude values, where the discretization circuit transmits the discrete amplitude values to a controller. The controller receives the discrete amplitude values from the discretization circuit, and communicates with each PHY, where a phase or frequency of the PHY signal is modified to minimize the constructive interference between the resonant frequencies.
