In recent times there has been a large growth in the number of small communications networks in the home or office. Cash registers, burglar alarms, computers and their peripherals all rely on small interconnected networks. A number of networking technologies are aimed purely at implementing these small home networks. Many remain costly, overly limited, or difficult to install in pre-existing buildings. This book details on these Communication Networking concepts. It goes on to demonstrate the wireless data transmission techniques and the power line data communication systems. The book aims to thoroughly explore the theoretical and practical aspects of power line carrier and wireless communications techniques.
