Automation using Power Line Communication

the main purpose of power line communication is digital data transmission/reception via power lines. The power line communication uses existing power line infrastructure for communication purpose. This concept provides comprehensive overview to the use of power line for communication purpose ranging from channel characterization. A power line modem is all in one devise which consist of an encoder, decoder, modulator & Demodulator. Modem provide bidirectional half duplex communication over the mains of any voltage up to 230V AC & for frequency 50Hz or 60Hz. Duplex communication suggest that it will either transmit or receive information at a time however not each at a same time. Normally module is in reception approach all the time listening to incoming communication on the power line. Once an application gives serial data to transmit on its RXin pin it alternation over to communicate & communicate the data though power line. Power line communication is used in this work to implement a control network. The goals are to reduce the impact of wireless interference on smart home control network and unnecessary energy consumption of a smart home. The Home automation will have master unit that will control all the slave unit across power line medium. While designing the network it is necessary to develop a system that integrate all electric apparatus in Home or Office.
