1 Future Communications Roadmap
John Micallef Dean Lamiano AGCFG #3 & ACP WG-C#11 18-19 September 2006, Brussels European Organisation for the Safety of Air Navigation

2 Contents Action Plan 17 Input to Roadmap VHF-band evolution
L-band evolution C-band evolution Commercial solutions Next Steps

3 Future Communications Study Action Plan (AP) 17
Technical Theme 4: Identify the communication roadmap Objective: Create a roadmap describing the communication infrastructure evolution Task 4.1 Communication Roadmap: In support of the communications operating concept, create a roadmap for the evolution of the communication infrastructure, specifically focusing on the introduction of the potential new technologies, and identifying the applicable airspace, phases of flight, and services supported

4 Future Communications Study AP 17 – Communications Roadmap
2004 2005 2006 Today 2007 Technical Themes Extend Current System Freq Mgmt Initial COCR ID Mobile Comm Ops Concept COCR (V1.0) Final - COCR (V2.0) Investigate potential technologies for mobile communication Pre-screen Investigation Simulation Communications Roadmap Roadmap Flexible Airborne Comm Architecture Feasibility Spectrum Band Investigation Band Studies Business Themes Create Multi- National Framework ICAO – ANC WG-C Create Industry Interest SESAR, ICNS, RTCA ATMAC Stakeholders Business Model

5 FCS Roadmap Considerations
User Inputs COCR Roadmap Spectrum Environment Regional Considerations

6 User Input U.S. ATMAC European States Use VHF band and existing technologies and equipment as long as possible Prepare for digital communications to support anticipated shift in operational paradigm Ensure timely technology decisions Ensure solid business case for new technologies Ensure solutions resolve local issues, and are globally applicable Sustain voice communications in VHF Band as long as possible Sustain future operation of voice communications in the VHF band by expanding 8.33 services (vertical expansion and potentially into the upper VOR band) Foresee a change in paradigm in the 2020 timeframe where additional capacity is provided by making data the primary mode of communications Given this short timescale to develop and implement new technologies, a decision has to be made soon. Target a global solution, but one that focuses on the requirements of the high-density core areas Demonstrate a solid business case for the introduction of future systems In the case of Satellite communications, consider options of having a dedicated ATM system vs. sharing the infrastructure with other services. Facilitate the transition to a new system by considering the introduction of a digital voice service. This is a desirable step but not critical. Sustain voice communications in VHF Band as long as possible Make optimum use of current equipage 8.33 kHz channel spacing is the preferred first alternative only when current 25- kHz spectrum no longer meets operational needs New technical solutions should be pursued only after all non-equipment solutions have been exhausted Spectrum allocation Policies and procedures Aeronautical Data Link System (ADLS) is important Use existing VHF capabilities / equipment (VDM2, 1090 MHz, UAT) to provide ADLS until Future Communications Study decisions and milestones are set Commit to a data link technology, schedule, and funding by 2007. AOC should remain separate from ATS communication
