Development of Intercom System using Power Line Carrier Communication Utilizing Existing AC Electrical Wiring

Telephony system is been a existing for decades, but till today the user has to rely on some service provider for communication. Nowadays the power line network has globally evolved so that they are present even in remote localities. So the idea of making use of existing power lines as a communication channel for telephony system is proposed in this article. Although this system cannot be utilized for long distance communication it can be used for small businesses, offices, home and organizations instead of a separate intercom system. An electronic interface with the power line network and its design considerations and practical implementation to the power line infrastructure is presented. The deal is to design a power line communication network for low voltage distribution lines. Here the existing electrical wiring of in-house power supply is utilized for voice communication. Power line network has developed and wide spread worldwide in every building and infrastructures. We develop a plug and play design so that the device can be portable and can be inserted into any electrical plug socket anywhere any time without need for any change in settings or adjustments. This voice over power line network is designed to operate at frequency of 50Hz and 220 volts AC supply.
