Voice and data communication over power transmission lines

Project Title

Voice and data communication over power transmission lines

Project Area of Specialization Information & Communication TechnologyProject Summary

Voice communication and data transmission at a time on a single existing power line that reduces the complexity of so much wires used in communication system and it is applicable in a large automated area with low cost and easy installation process. The message (voice, ) is modulated with a high frequency carrier by frequency modulation (FM) or frequency shift keying (FSK) process and after amplification it passes to the power line through the bidirectional coupler. At the receiver section the signal (FM or FSK) is recovered by coupler and then demodulated. The demodulated signal is then passed through the low pass filter to recover the voice  signal and a comparator is used to recover data signal.

Project Objectives

To communicate areas where wireless communication not reached or expensive and  communicate where electricity reaches

Project Implementation Method

Using duplexer we can both transmit and receive messages and Rf Transformer and etc components used

Benefits of the Project

Reduce cost of extra wires for communication 

Technical Details of Final Deliverable

In-house PLC is a carrier current system, operating as an unintentional radiator, which sends radio frequency energy by conduction over electric power lines that are not owned, operated or controlled by an electric service provider. The electric power lines may be aerial (overhead), underground, or inside the walls, floors or ceilings of user premises. In-house PLC devices may establish closed networks within a user’s premises or provide connections to Access PLC networks or both 
This application occurs within a building where both ends of the communication link are located. The distance between communication ends is typically less than 100 meters. This system is attractive because no extra wiring is needed within the building. The power lines used belong to the user and not the electricity provider They are connected to the building wiring and uses electrical sockets as their access points. It makes use of a wireless transceiver to access the broadband network 
The typical applications of in house power line voice communication are that, this system allows easier and more efficient voice communication between the end users inside a building [28]. In addition, networking and sharing common resources such as printers are other applications of this technology the in-house and Access PLC network
