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
WAEA On-Board Infrastructure ah hoc group 9
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.)
WAEA On-Board Infrastructure ah hoc group 10
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
WAEA On-Board Infrastructure ah hoc group 11
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
WAEA On-Board Infrastructure ah hoc group 12
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)
WAEA On-Board Infrastructure ah hoc group 13
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
WAEA On-Board Infrastructure ah hoc group 14
Ethernet Switch Unit • The Ethernet Switch Unit provides a wired
network connection between the connected systems based on IEEE 802.3 Ethernet
• Form factor : 2 MCU (tbc), location may be E-Bay
WAEA On-Board Infrastructure ah hoc group 15
High-Speed Satellite System • The High-Speed Satellite System provides the
broadband communication link between the aircraft and the ground via geo-stationary / orbiting satellites
• Access to satellite-based high-speed data communications
• Consists of antenna(s) and the transceiver(s) part• Items to investigate :
What antenna(s) types and what reception system may be used ? With what dimensions and weights ? Where might the antenna(s) be installed on the a/c ? (at top of the fuselage or within the vertical stabiliser structure)
