This document discusses aeronautical communication architecture. It describes how wireless cabin architecture uses technologies like UMTS, Bluetooth, and wireless LAN to provide connectivity to passengers. A satellite segment connects the cabin to terrestrial networks for global coverage. Technical details are provided on bandwidth and modulation for each technology. Benefits include passengers using their own devices and maintaining connectivity, while challenges include not replacing wired infrastructure.

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.

satellite system
 Support the air traffic control and for
weather observations
 Higher reliability, integrity, and operational
continuity are required
SATELLITE CONNECTION

13. SATELLITE CONNECTION
 It will cover the areas especially
over oceanic regions
 Bandwidth
 Geostationary Satellite

14. TECHNICAL OVERVIEW
 UMTS
(The Universal Mobile Telecommunication System)
Third generation mobile communication system
Developed within the IMT-2000 frameworks
The air interface UTRAN (UMTS terrestrial radio access),applicable in two existence
duplexing scheme-
 UMTS-FDD
 UMTS-TDD

15. TECHNICAL OVERVIEW
 Coverage range is capacity
dependent that is from 200m to
1.4 km. known as “cell breathing”.
 Maximum bit rate is 2mbps.

16. TECHNICAL OVERVIEW
 BLUETOOTH
 Operates in 2.4 GHZ ISM band.
 Uses a (Frequency-hopping spread
spectrum) FHSS technique to minimize
interference.
 Has a range 10 meters.
 Bandwidth is 1 MHz
 Maximum bit rate is 1 Mbps.

17.  WIRELESS-LAN (W-LAN)
 Provides Superior bandwidth compare to any cellular technology
i.e. 26MHz.
 Operates in 2.4GHz ISM band.
 Uses DSSS (Direct sequence spread spectrum) technique to
minimize interference
 Maximum bit rate is 11Mbps.

TABLE OF TECHNICAL OVERVIEW

20. 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.

21. 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)

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

23. 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. It
focusses on the wireless services such as UMTS and WLAN to connect
the passengers via satellite or terrestrial services. In aeronautical
scenario, global coverage is quite needed for providing a continuous
service. Therefore, satellite communication became indispensable and
together with ever increasing data rate, requirement of applications,
aeronautical communication meets an expensive market.
