Digital notice board implementation via power line communication

PLC (Power line communication) is a technology that provides high speed communication of voice and data and its is very cost effective method. It has been successfully implemented in many applications in real time. In this project one such application is used to digitize an institution by replacing circulars or notice boards by digital notice boards. Frequent updating is easy with a centralized systems. Data's are sent through existing power line to a particular power line node or various nodes. The information is obtained from server and it is displayed using LCD at the reception. when a message is received it is intimated to students using a voice board. A personal Computer, power line modem, voice board and an LCD display are used to design digital notice board via power line.
