7 CHAPTER 1 GENERAL INFORMATION INTRODUCTION The Department of Defense uses the 960 1215 MHz band for the Joint Tactical Information Distribution System (JTIDS), the Multifunctional Information Distribution System (MIDS), and other functionally similar Tactical Link systems (termed collectively, Link 16 Terminals ). Based on its importance for aeronautical radio-navigation and supporting systems, the Department of Transportation (DoT) also has interests in this frequency band. Rapid growth in commercial and civil aviation during the 21st century shall increase the importance of ensuring spectrum supportability for existing and new systems that enhance air traffic safety.

8 The Department of Defense and the DoT shall work cooperatively to support National Telecommunications and Information Administration (NTIA) action to protect both Link 16 and civil/commercial aeronautical systems sharing this portion of the radio frequency (RF) spectrum . Ensuring ELECTROMAGNETIC COMPATIBILITY (EMC) is the cornerstone to spectrum management and supportability, and optimal system operation. Thus, the EMC features of Link 16 systems used throughout the Department of Defense shall be certified to ensure compliance with applicable requirements and specifications. PURPOSE Pursuant to reference (a), this Regulation implements spectrum management for Link 16 Terminals.

9 With specific focus on EMC Features certification as stipulated in refer-ence (b), this Regulation: implements the policy established in reference (b), identifies responsibility, delineates the process, and promulgates step-by-step procedures and associated timelines. This Regulation also implements the Link 16 EMC Features certification requirement of reference (c) as a prerequisite for uncoordinated operation of Link 16 equipment in the United States and possessions. The Link 16 EMC Features Certification Performance Specification has been incorporated as Appendix 1 to this Regulation, with the Link 16 EMC Features Certification Test Plan as Attachment 1 to Appendix 1.

10 Both were initially drafted as separate documents. This incorporation is in full compliance with the structure and format requirements for DoD Issuances as specified in chapter 4 of DoD (reference (d)). 6 DoD , April 26, 2005 C2. CHAPTER 2 LINK 16 TERMINAL EMC FEATURES CERTIFICATION POLICY AND RESPONSIBILITIES POLICY Within the Department of Defense, Link 16 Terminal EMC Features shall be certified by the Program Executive Officer - Command, Control, Communications, Computers, Intelligence and Space (PEO C4I&S), who shall then submit the EMC Features certification package to the Navy-Marine Corps spectrum Center (NMSC).
