A next-generation tactical system architecture for tetherless communicators

The authors propose a tactical system architecture for the 21st century that will give tetherless communications to all users, with access to a switched network implemented in a satellite constellation. Early in the next century, when today's tactical mobile communications systems are outmoded, an all-wireless access system such as this will be feasible. Lessons learned in Desert Storm tell that mobility of communications is of the utmost importance to a fighting force; network access in this new architecture will be via a variety of personal mobile and portable terminals that extend complete mobility to all users. A terrestrial backbone network using many vehicles, LOS links, and much (frequency) planning will no longer be needed; the architecture discussed is a Land Mobile Satellite (LMS) system. Feasibility of such a tactical system architecture is argued and some promising technology options available to system architects and designers are identified.<>
