10.   SATELLITE CONNECTION ARYABHATA CARTOSAT-2C
11.    The composition of Air traffic satellite system  Support the air traffic control and for weather observations  Higher reliability, integrity, and operational continuity are required SATELLITE CONNECTION
12.   SATELLITE CONNECTION  It will cover the areas especially over oceanic regions  Bandwidth  Geostationary Satellite
13. 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
14.   TECHNICAL OVERVIEW  Coverage range is capacity dependent that is from 200m to 1.4 km. known as “cell breathing”.  Maximum bit rate is 2mbps.
15.   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.
16.  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. TECHNICAL OVERVIEW
17.   TECHNICAL OVERVIEW  Coverage range is 20-100 meters.

19. 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.
20.   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)
21.  DISADVANTAGES  It should not be seen an alternative to a wired architecture in aircraft.
22.   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.
