Course Overview:

Joint Range Extension Applications Protocol Training | JREAP Training Workshop Course – Hands-on

Joint Range Extension Applications Protocol Training, JREAP Training Workshop, is a 4-day JREAP course covering details of 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. Participants of JREAP Training workshop will also learn about the foundation of Joint Range Extension (JRE) concept and how the Internet Protocol (IP) technologies utilized for transfer and transport tactical data using integration of Data Links networks and tactical IP networking.

JREAP training workshop provides knowledge of system capabilities and limitations, system foundation, engineering, operation, performance, qualification and optimization of JREAP systems. For over 25 years ENO has supported land, air and maritime military operations, defense organizations and government agencies around the world to deliver situational awareness consulting and training and enhanced operating effectiveness of mission critical SATCOM, UHF, VHF, TDL, Link 11/16/22, VMF, SADIL, and JREAP systems. Our team of skilled instructors, consultants and JREAP experts assist participants on all aspects of the JREAP lifecycle processes. In accordance with DoD Instruction 4630.8, it is DoD policy that all Joint and combined operations be supported by compatible, interoperable, and integrated Command, Control, Communications, and Intelligence (C3I) systems.

Highlights of JREAP Training Workshop:

• Position the activities in the complete JREAP system certification, verification and validation process
• Use testing terminology in a JREAP system (JREAP A, B and C)
• Use risk to drive the validation efforts
• Make decisions on how to test JREAP systems for defects more efficient
• Plan appropriate (risk-based) techniques to find JREAP defects
• Plan appropriate (risk-based) functional testing techniques
• Choose appropriate tests for acceptance, that is, compliance to requirements
• Manage JREAP A, B and C test data and information
• Manage JREAP A, B and C testing requirements and test failures
• Document the TDL test plans (activities, resources, risks)
• Use Interoperability Test and Evaluation and Requirements Transformation (iSMART) for JREAP

Joint Range Extension Applications Protocol Training – Customize It:

• If you are familiar with some aspects of this Joint Range Extension Applications Protocol Training Workshop course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the Joint Range Extension Applications Protocol Training Workshop course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Joint Range Extension Applications Protocol Training Workshop course in manner understandable to lay audiences.
