Project 25 (P25) is a suite of global user-driven digital standards for two-way non-public radio communications networks. P25 has been adopted by many industries, including utilities, transit, petroleum, and chemical companies, and airport authorities that rely on mission-critical communications and interoperability with public safety agencies in an emergency. The operating distance of these wide-area networks can be up to 32 miles, far exceeding mobile cellular networks. Additionally, the physical transmission of P25 is specifically designed to be ultra-reliable, even under simulcast transmission from multiple sites. This book discusses the P25 goals and system model, and its components, features, functions, services, interfaces, infrastructure and configurations. It will also review the P25 channels, physical transmission, vocoders, and network control elements, as well as the conventional and trunking systems, the coverage configurations such as simulcast, multicast, and voting as well as the consoles and subscriber units. The evolution of land and digital mobile radio technologies will also be covered.
