project will define a system architecture for wireless access (UMTS, W-LAN
and Bluetooth) in an aircraft cabin. The passenger will have the possibility
to use its own personal equipment (mobile phone, laptop). For this, the
project will develop a service integrator that maps the cabin services
on a satellite bearer to be connected to the terrestrial infrastructure.
concept of the wireless cabin access will be demonstrated in flight via
satellite using an Airbus long-haul aircraft. The cabin services will provide
mobility, VPNs and AAA functions which need to be developed for the mobile
Figure 1: WirelessCabin System Architecture
The architecture consists
of (i) several wireless access segments in the aircraft cabin, (ii) a satellite
segment for interconnection of the cabin with the terrestrial telecom networks,
and (iii) an aircom service provider segment supporting the integrated
The CMHN concept will be elaborated
and the required protocols will be analyzed and designed. A concept for
providing different quality of service with variable bandwidth for each
of the access standards will be developed and a handover strategy among
several available satellite segments with eventual asymmetric bandwidth
in up- and down-link will be defined.
For the wireless access, the
propagation channel in the aircraft will be determined by a channel measurement
campaign, and channel statistics and a model will be derived. This will
yield to an interference analysis to determine the cell topology, but also
the impact on avionics equipment in flight deck and bay.
the protocol side the project will investigate the effect of the propagation
delay on UMTS protocols and an encapsulation of UMTS services over Bluetooth
will be developed.
Furthermore, a market survey
will perform passenger and airline interviews, and a business relation
model between service providers, airlines, and satellite providers will
