Link 16 and Joint Range Extension Applications Protocol (JREAP Training) Bootcamp

Link 16 and Joint Range Extension Applications Protocol (JREAP Training) Bootcamp is a 3-day that covers principles of Tactical Data Link (TDLs), Link 16, and Joint Range Extension Applications Protocol (JREAP).

Link 16 has many advantages over other existing tactical data links such as Link 11. The network in Link 16 is “nodeless” which means that the Link 16 network does not depend on any one of the terminals with a distributed operation. Link 16 terminals can support many levels of system and network management such as: monitoring of link or the equipment status by an external processor.  MIL-STD-1553, X.25, or Ethernet hardware and software is used for host traffic interchange. Terminals can offer a direct voice I/O at 16-kbps CVSD and 2.4-kbps LPC-10 voice coding.

Operational activation of Link-16 network has multiple steps such as overall coordination planning by joint planners with overall coordination plan, designation of net time reference(s), interoperability roles, and crypto allocations. An individual Net planner can prepare mission files such as initialization data, coordination nets, and continuity of operation roles.

Joint Range Extension Applications Protocol Training (JREAP) part covers key concepts such as system foundation, engineering, operation, performance, qualification and optimization of JREAP systems and protocols: JREAP-A or Announced Token Passing protocol for half-duplex communications, JREAP-B or synchronous or asynchronous point-to-point mode of the JREAP, and JREAP-C using the Internet Protocol (IP) in conjunction with UDP or TCP.

Learning Objectives

Upon completion of the Link 16 and JREAP training, the participants will be able to:

  • Explain the basic principles and concepts of Link 16, JRE and JREAP
  • Describe Link 16 and JREAP standards, requirements and operational models
  • Describe the history and background of variety of Link 16 terminals
  • Describe the key concepts, features and mechanisms behind Link 16 and JREAP operation
  • Illustrate potential Link 16 and JREAP deployment scenarios
  • List the basic principles of JREAP A, B and C procedures and methods
  • Explain Link 16 and JREAP process and Interoperability testing methodology
