Aerospace Vehicle Systems Institute Update on WAIC Issues

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

Aerospace Vehicle Systems Institute Agenda § AVSI and WAIC § Importance of WAIC § ITU-R Working Party 5 B Update § Issues Discussed and Documents § 37 -38 GHz band § 22. 55 -23. 15 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

Aerospace Vehicle Systems Institute AVSI and WAIC § 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 Do. D (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.

Aerospace Vehicle Systems Institute AVSI and WAIC § 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

Aerospace Vehicle Systems Institute Importance of WAIC to the Aviation Industry § 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

Aerospace Vehicle Systems Institute ITU-R Working Party 5 B - Update WP 5 B 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 § WP 5 C (Fixed Service) – (37 -38 GHz band) § WP 7 B (Space Services) – (37 -38, 22. 55 -23. 15 GHz bands) Slide 5

Aerospace Vehicle Systems Institute WAIC Update – 37 -38 GHz Band § WRC-12 Agenda Item 1. 12 seeks to determine if the aeronautical mobile service can be removed from the 37 -38 GHz band § WAIC might be able to use this band § Want to protect Space Research and Fixed Services § WP 5 B provided technical information (PDNR) to WP 7 B and to 5 C (responsible groups) § WP 5 B 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

Aerospace Vehicle Systems Institute WAIC Update – 22. 55 -23. 15 GHz Band § WRC-12 Agenda Item 1. 11 seeks to permit the Space Research Service in the 22. 55 -23. 15 GHz band. § Liaison statement to WP 7 B sent that states WAIC will not consider this band. Slide 5

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 § 4200 -4400 MHz § 5030 -5091 MHz § 9300 -9500 MHz Potential Future WRC Agenda Item § Focus on “Aviation” bands § Review current RTCA, Euro. Cae, 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

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

Aerospace Vehicle Systems Institute ITU-R Working Party 5 B - 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
