ABSTRACT:
The present invention relates to a communication system and method in a ship area network. In a network of a structure including a plurality of shielded regions, communication is performed between terminals provided in the shielded region by using wireless communication, and communication is performed between terminals provided in different shielded regions by further using power line communication, optical communication, or the power line communication and the optical communication in addition to the wireless communication. Therefore, it is possible to obtain advantages of minimizing inconvenience, which is caused by using only wire communication in the related art, and enlarging a working area.
