A state-of-the-art reference, how-to guide, and problem-solver wrapped up in one complete source, this benchmark work brings you quickly up to speed on PLC network architecture, functionalities, security issues, and applications. You get details on PLC modems, transformers, and other equipment along with PLC installation and configuration guidelines that cover everything from choosing the topology for a PLC network to configuring parameters under Windows or Linux/BSD. The book spells out steps to install PLC in homes followed by design and configuration procedures for PLC business networks that cover all issues involving network architecture, standard and equipment selection, security, and other essentials. The book also explores the development of community-wide PLC networks and the emergence of hybrid PLiEthernet-Wi-Fi applications. Supported by real-world examples and 280 illustrations, this hands-on resource takes you to the cutting edge of power line communications and helps you tap its rich potential moving forward.
