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.
AERONAUTICAL COMMUNICATION ARCHITECTURE
WIRELESS CABIN ARCHITECTURE
GSM telephony is prohibited in commercial aircraft
TDMA technology
Wireless access technologies
WIRELESS CABIN ARCHITECTURE
CABIN SEGMENT
I. Wireless LAN for IP services
II. UMTS (The Universal mobile telecommunication system) for personal and data communications
III. Bluetooth for IP access for transport of UMTS service
WIRELESS CABIN ARCHITECTURE
SPACE SEGMENT (Satellite segment)
I. For interconnection of the cabin with the terrestrial telecom networks.

SATELLITE CONNECTIONARYABHATA CARTOSAT-2C
The composition of Air traffic satellite system
Support the air traffic control and for
weather observations
Higher reliability, integrity, and operational continuity are required

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
TECHNICAL OVERVIEW
Coverage range is capacity
dependent that is from 200m to
1.4 km. known as “cell breathing”.
Maximum bit rate is 2mbps.
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.
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
SERVICE INTEGRATOR AND DIMENSION
INTEGRATOR The service integrator will provide the
interfaces for the wireless and wired service access points in the cabin.
DIMENSIONThe 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.
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)
DISADVANTAGES
It should not be seen an alternative to a wired architecture in aircraft.
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.
