Abstract

The present invention relates to magnetic field based power transmission line communication interface controller for subscriber'"'"'s terminal to receive voice, data and other kinds of electrical signals converted from acoustic wave that is conveyed over the PAN communication network, or to transmit information from the subscriber'"'"'s terminal to designated destination over the PAN communication network. The interface controller of the present invention is characterized by pumping acoustic wave into the microwave within the magnetic flux envelope generated along the magnetic field based power transmission line(PAN).

Claims

1. A magnetic field based power transmission line interface controller for power transmission line communication transmitting acoustic wave within the microwave of the magnetic field envelope formed along the power transmission line comprises:

an antenna to reflect microwave resonating in the high frequency band ranging from 30 GHZ to 24,000 GHZ;

a transmitter/receiver connected to said antenna, to receive or radiate with said antenna the acoustic wave carried within said microwave;

a piezoelectricity converter connected to said transmitter/receiver to receive said acoustic wave, and for generating electric signal from the acoustic wave vibration;

an input/output controller to receive said electric signal, controlling input/output process of the terminal device interconnected to a connector and to process synchronous signal and native address information in the memory through clocking, and to carry additional signal property data into the signal transmitted by said terminal device.

2. A magnetic field based power transmission line interface controller in accordance with claim 1, further comprises a piezoelectric device within the piezoelectricity converter having at least 10⁻

12 volt of nuclear piezoelectric film sensing property.
