3. INTRODUCTION
Communication b/w aircraft cabin to the terrestrial network via
satellite segment.
Global coverage is essential for providing continuous service.
 Wireless services such as UMTS, Bluetooth and W-LAN in aircraft cabins.
Airlines are increasingly requiring in-flight services to offer similar
entertainment or business experience to passengers as their terrestrial
counter part.

TABLE OF TECHNICAL OVERVIEW

7. SERVICE INTEGRATOR AND DIMENSION
INTEGRATOR
 The service integrator will provide the
interfaces for the wireless and wired service
access points in the cabin.
DIMENSION
The system dimensioning process can be
structured in several steps:-
 Determination of gross traffic per aircraft
using the multi-service model.
 Determination of the timely and locally
varying traffic.

8. ADVANTAGES
 The passengers of both business and economy could use their own wireless
equipment.
 The passengers can be reached under their usual telephone number, they may have
available telephone numbers or other data stored in their cell phones or PDAs
 Their laptops have the software they are used to, the documents they need and with
their personalized configuration (starting web site, bookmarks, address book).
 Saving of the investment that would suppose the installation of terminals (screens,
stations, and wired telephones)

9. DISADVANTAGES
It should not be seen an alternative to a wired
architecture in aircraft.

10. CONCLUSION
Airlines aims at providing various other
entertainment and communication equipment's in
the nearest future. Since people are becoming
more attached to the communication resources
such as Network Interface Cards and dial-up
connections, airlines have to accommodate such
facilities for the betterment of travel experience.
