ABSTRACT:
A system and method is provided for enabling data transfer over the same electrical routing network utilized by the mobile device to obtain electric power from an external power source. The system includes a contact base connected to a power supply, and mobile device adapters. The contact base is a flat surface that comprises a segmented conductive area with conductive contact pads on the surface, and a plurality of base controller modules that detect the presence of compatible mobile devices placed on the contact surface and routes the electrical power through the contact points on the surface to the compatible mobile devices accordingly, after a handshake protocol. The data communication portion of the system comprises a power line communication bypass circuit and a repeater for power line communication either within or adjunct to the power supply that powers the contact base. It further comprises, on the mobile device side, a power line communication adapter which converts the analog waveform the mobile device receives through its electrical contacts into digital data and vice versa.
