Next Generation (XG)
Abstract
(U) The Next Generation (XG) program developed both the enabling technologies and system concepts to provide dramatic improvements in assured military communications in support of a full range of worldwide deployments through dynamic spectrum access. U.S. Forces face unique spectrum access issues in each country in which they operate due to competing civilian or government users of national spectrum. These constraints must be reflected in all force planning and may preclude operation of critical systems. Coalition and allied operations are even more complex to manage, and may severely limit the U.S. ability to fully exploit its superiority and investment in information technology. The XG program developed the theoretical underpinnings for dynamic access to the spectrum, the technologies and subsystems that enable dynamic access, and the system prototypes to demonstrate applicability to legacy and future DoD radio frequency emitters. The program investigated methods to leverage the technology base in microelectronics with new waveform and medium access and control protocol technologies to construct an integrated system. The program developed, integrated, and evaluated the technology to enable equipment to automatically select spectrum and operating modes to both minimize disruption of existing users, and to ensure operation of U.S. systems. The XG program also developed and demonstrated a set of standard dynamic spectrum adaptation technologies for legacy and future emitter systems for joint service utility. The XG communications technology transitioned to the Army for implementation in a range of current and future communication systems including the Joint Tactical Radio Systems clusters and the Enhanced Position Location and Reporting System - Extended Frequency (EPLRS-XF) radio systems.
