On-board infrastructure

ad hoc group

Revised by Rolf Goedecke

August 18, 2000

background
Background
  • Growing Airline/Passenger demand for information and communication services on board an A/c
  • Allow competition based on standardized platforms
  • Services including in-flight email, Intranet/Internet Web content
  • Technology enablers are available or will be available soon
  • Preparation of a common system architecture capable of supporting multiple applications

On-board infrastructure generic block diagram: basis for discussion

Required a/c infrastructure to allow new functions, such as

- crew e-mail,

- crew airline intranet access,

- passenger access to intranet,

- passenger access to e-mail...

- NSU ( Network Server Unit, host for A/c intranet pages, e-mail proxy... )- Gatelink ( Wireless a/c – to - ground-network communication link in near airport on-ground terminal environment )- Cabin W-LAN ( wireless link inside the cabin between NSU and e.g. laptops, Credit card readers ... )- Interfaces to Cabin equipment and Satcom

considerations
Considerations
  • High-speed communication und data exchange via wired and wireless LAN
  • Server technology as platforms for several applications
  • Allow for High-Speed Satellite Communication
  • Modular system architecture suitable for S/A and L/R aircraft
  • Possibility for easy extension in a modular way
functionalities
Functionalities
  • The proposed system functionality may include as an example,
  • but not be limited to, the following:
  • E-mail services
  • Intranet Access
  • Internet Access
  • Airline specific access to the Airline intranet (such as Booking Systems, Airline Logistics, Mobile Credit Card Reader, Flight Connection Information etc.)
concept
Concept
  • The concept for the On-Board Infrastructure
  • is a system consisting of the following major parts:
  • Network Server Unit (NSU)
  • Terminal Wireless LAN
  • Cabin Wireless LAN
  • Ethernet Switch Unit
  • High-Speed Satellite Data Transceiver
  • Interfaces to communication Systems
  • Interfaces to other systems
network server unit nsu
Network Server Unit (NSU)
  • Closely linked with the highly customized cabin and passenger-related functions (e.g. E-Mail and Intranet/Internet, cabin crew applications)
  • Provides system processing and network communication services for customized S/W applications
  • Form, fit and functions of NSU shall be closely linked to the architecture of the In-Flight Entertainment System
  • (may be according to ARINC 763)
  • Form factor : 4 / 6 MCU
  • To be installed in E-Bay or close to the IFE system
terminal wireless lan
Terminal Wireless LAN
  • The Terminal Wireless LAN is used to bridge a wireless connection between the on-board LAN and a ground-based LAN typically at an airport
  • The Terminal Wireless LAN includes the Terminal Wireless LAN Unit and the Antenna
  • Potential applications are Software Updates (Core, News, Web Pages) and access to aircraft status data
  • Interfaces to the NSU
  • Based on ARINC 763
  • Form factor according to ARINC 763, location is fuselage (external antenna)
cabin wireless lan
Cabin Wireless LAN
  • The Cabin Wireless LAN provides a wireless network connection between devices within the aircraft structure and those systems connected to the wired Ethernet LAN
  • The Cabin Wireless LAN includes the Cabin Wireless LAN Unit and the Antenna(s)
  • Potential applications are crew access to electronic docs and maintenance data, wireless credit card reader, …
  • Interfaces to the NSU
  • Based on ARINC 763
  • Form factor according to ARINC 763, location is aircraft dependant on measurement/coverage tests
