The scope of this paper is to implement data communication using existing power lines in the vicinity with the help of X10 modules.

However, of lately the traditionally used channels have come to a saturation level and there was need to explore new kind of technology which is simpler to implement and is not as expensive as other related technologies. The basic idea of power line carrier communication system (PLCC) is to use the existing power cable infrastructure for communication purpose. Our system will mostly be implemented in small areas such as residences, offices, etc. and with the use of this system; various kind of devices can be controlled remotely. The main benefit of this system stands to the residential users of making their dream of automation of their house. With just a simple set up of a transmitter and receiver, and ensuring equal phase supply, one can control a host of devices and enjoy the leisure of living in a fully automated house. Another major factor is the ubiquity of the medium - power outlets are commonly found and available throughout the house or the office and may very well serve as communication nodes. The external electrical grid can also be used for many applications whose solutions provide many opportunities for equipment vendors and utilities to offer new services, features and products, cut costs of current services, fully automate manual processes and procedures. It can also be used to improve current products, monitor and collect valuable data, offer remote service options and create new business and revenue streams utilizing the existing infrastructure [1]. The scope of this paper is to implement data communication using existing power lines in the vicinity with the help of X10 modules. The system basically consists of two modules, a transmitter and a receiver that can communicate with each other using the existing power cables in residential and commercial areas. This paper elaborates on only the transmitter end of the PLCC system. The paper is organized as follows. Section II discusses various PLCC standards. Section III explains the technology used and Section IV presents the system design considerations. The applications are mentioned in Section V. We discuss the limitations of our system in Section VI and conclude in Section VII. II. PLCC STANDARDS There are various standards available that involve modulation of the signal using carefully selected frequency range. These standards also provide robustness to the system to work properly under any conditions, since power lines may have many undesirable influences on the communication systems [1]. These standards are briefly described as follows. A. Consumer Electronics Power Line Communication Consumer Electronics Power Line Communications Alliance (CEPCA) is a PLCC standard being developed by Sony, Mitsubishi and Panasonic. CEPCA is expected to deliver speed up to 170 Mbps using existing power lines. B. European Telecommunications Standards Institute European Telecommunications Standards Institute (ETSI) will progress the necessary standards and specifications to cover the provision of voice and data services over the mains
