3. AVSI and WAIC What is AVSI What is WAIC
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.

4. 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
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

5. 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

6. ITU-R Working Party 5B - Update
WP5B is lead ITU-R Group
WAIC Preliminary Draft New Report
Inputs from CEPT, US and Brazil – 4th 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. 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. 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. 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. 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. 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
