Tactical Communications for the Digitized Battlefield


Book Description

Traditional tactical communications systems consist of a number of separate subsystems with little interworking between them and with external sensors and weapons systems. Combat net radio (CNR) has provided the high-mobility communications required by combat troops, while trunk communications systems have provided high-capacity communications between headquarters at the expense of mobility. The focus of this book is on new, information-age technologies that promise to offer seamless integration of real-time data sharing, creating a single logical network architecture to facilitate the movement of data throughout the battlespace. Because the structure of this network is constrained by the fundamental trade-off between range, mobility and capacity that applies to all communications systems, this network is unlikely to be based on a single network technology. This book presents an architecture for this network, and shows how its subsystems can be integrated to form a single logical network.
