1 Aerospace Vehicle Systems Institute Update on WAIC Issues ITU-R Working Party 5B and Future Regulatory Considerations Joe Cramer December 16, 2009

2 Aerospace Vehicle Systems Institute Agenda AVSI and WAIC Importance of WAIC ITU-R Working Party 5B Update Issues Discussed and Documents GHz band GHz band ICAO and Future Course of Action Initial Thoughts on Potential Frequency Bands Potential Future WRC Agenda Item Role of ICAO and ITU-R Slide 5

3 Aerospace Vehicle Systems Institute What is AVSI Aerospace Vehicle System Institute - A cooperative of aerospace industries and government agencies. Members include Airbus, BAE Systems, Boeing, Bombardier, Embraer, Goodrich, Gulfstream, GE Aviation, Honeywell, NASA, United Technologies, US DoD (observer). Brings together industry, government and academia to focus on developing improved aerospace vehicles. Creates an environment for collaboration on R&D; investigates emerging technologies; influences standards and policies to promote cost effective systems development and certification. What is WAIC An official project of AVSI Radiocommunications between two or more points on a single aircraft. May include integrated wireless components and/or installed components. Part of a closed, exclusive network required for operation of the aircraft. Do not provide air-to-ground or air-to-air communications. Only safety related applications are being contemplated. AVSI and WAIC

4 Aerospace Vehicle Systems Institute Potential WAIC Applications Low Data Rate, Interior Applications: Cabin Pressure Engine Sensors Smoke Detection Sensor Data (unoccupied and occupied areas) Low Data Rate, Outside Applications: Ice Detection Landing Gear/Brake Temperature Sensors Engine Sensors High Data Rate, Interior Applications: Flight Deck/Cabin Crew Video and Audio Air Data Sensors Engine Prognostic Sensors High Data Rate, Outside Applications Structural Sensor Data Avionics Communications Bus Active Vibration Control AVSI and WAIC

5 Aerospace Vehicle Systems Institute Wireless connectivity can improve flight-safety and operational efficiency, while reducing manufacturing and operational costs. Wireless link for redundancy Reduce aging wiring and associated conditions Weight Reduction Potential – environmental benefits Increased Reliability Fewer connector pins/failures, cracked insulation, & broken conductors Mesh networks could provide redundancy Improve Operational Efficiency Ability to obtain more data from aircraft surfaces Less wire maintenance to remediate chafing conditions Simplify and reduce life-cycle cost of airplane wiring Reduced weight should save fuel costs Importance of WAIC to the Aviation Industry

6 Aerospace Vehicle Systems Institute ITU-R Working Party 5B - Update WP5B is lead ITU-R Group WAIC Preliminary Draft New Report Inputs from CEPT, US and Brazil – 4 th meeting with inputs US and CEPT documents almost identical, Brazil provided Glossary of Terms Technical Characteristics and Operational Objectives Working Document upgraded to a Preliminary Draft New Report Next step is to make document a Draft New Report, and then Report Now must start considering whether an Agenda Item is needed Several Liaison Statements Sent WP5C (Fixed Service) – (37-38 GHz band) WP7B (Space Services) – (37-38, GHz bands) Slide 5

7 Aerospace Vehicle Systems Institute WAIC Update – GHz Band WRC-12 Agenda Item 1.12 seeks to determine if the aeronautical mobile service can be removed from the GHz band WAIC might be able to use this band Want to protect Space Research and Fixed Services WP 5B provided technical information (PDNR) to WP 7B and to 5C (responsible groups) WP 5B asks whether any of the classifications of WAIC can be acceptable Preliminary Political Analysis Most countries will consider keeping AMS allocation if studies support sharing with WAIC Slide 5

8 Aerospace Vehicle Systems Institute WAIC Update – GHz Band WRC-12 Agenda Item 1.11 seeks to permit the Space Research Service in the GHz band. Liaison statement to WP 7B sent that states WAIC will not consider this band. Slide 5

9 Aerospace Vehicle Systems Institute ICAO and Future Course of Action AVSI has started reviewing potential bands First bands reviewed - see input to ICAO WG-F meeting MHz MHz MHz Potential Future WRC Agenda Item Focus on Aviation bands Review current RTCA, EuroCae, ICAO, ITU-R protection criteria. Should make job easier at ITU-R Will require extensive technical analysis, marketing and education of aviation regulatory bodies Focus on Bands above 20? GHz Slide 5

10 Aerospace Vehicle Systems Institute Need for ICAO and ITU-R Regional Support If an Agenda Item is required, then support from APT and ICAO is required Important that world-wide allocation(s) be obtained Spectrum usage must fall within ICAO Convention Equipment certification must have same regulatory benefits as avionics and other aviation equipment The Service Definition chosen for WAIC requires support Slide 5

11 Aerospace Vehicle Systems Institute Thank You Joseph Cramer Regional Director Spectrum Regulatory Affairs Slide 20

12 Aerospace Vehicle Systems Institute Back up Slides Slide 20

13 Aerospace Vehicle Systems Institute ITU-R Working Party 5B - Issues Potential Service Issue What Service will WAIC applications be considered under? – Most likely Service is Aeronautical Mobile (Route) Service. ICAO and Arab States will most likely insist on this definition Slide 5

14 Aerospace Vehicle Systems Institute Radiocommunication Services A service involving the transmission, emission and/or reception of radio waves for specific telecommunication purposes (ITU Radio Regulations – Article 1, Definitions of Radio Services) The ITU Radio Regulations divide spectrum into Allocations and Services and Assignments Frequency bands are allocated to Services 41 Services defined by the ITU The regulatory treatment and strategy is impacted based on the type of radio- communication services (e.g. safety related vs. non safety related applications) Ground Station Aeronautical Mobile (Route) Service (AMS) - example: HF Voice – (2-30 MHz) Aeronautical Radionavigation Service (ARS) - example: Instrument Landing Systems (ILS) – ( MHz) Satellite Aeronautical Mobile Satellite Service Slide 21
