AERONAUTICAL COMMUNICATION Presented by-Under the guidance of- Akshay Kumar SinghDr. Shahanaz Ayub EC 3 rd YearElectronics & Comm. Engg

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. 2

STELLITE CONNECTION  The composition of Air traffic satellite system Support the air traffic control and for weather observations Higher reliability, integrity, and operational continuity are required 3 MTSAT-1R MTSAT-2R

SATELLITE CONNECTION (continue)  Effect of MTSAT Introduction Increases the traffic handling capacity for the air route. Improvement of safety. Great improvements in communication quality. 4

5 NM: Nautical Mile

WIRELESS CABIN ARCHITECTURE 6

WIRELESS CABIN ARCHITECTURE (continue)  CABIN SEGMENT 1. Wireless LAN for IP services. 2.UMTS (The Universal mobile telecommunication system) for personal and data communications. 3. Bluetooth for IP access & transport of UMTS services. 7

WIRELESS CABIN ARCHITECTURE (continue)  SPACE SEGMENT ( Satellite segment) For interconnection of the cabin with the terrestrial telecom networks. 8 SPACE SEGMENT

9  GROUND SEGMENT For interconnection to the terrestrial personal and data networks as well as the Internet backbone. WIRELESS CABIN ARCHITECTURE (continue)

SERVICE INTEGRATOR 10  Provide the interfaces for the wireless and wired service access points in the cabin.  Interface to the terrestrial networks at aircom provider site.

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 11

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

TECHNICAL OVERVIEW (continue)  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 1MHz. Maximum bit rate is 1 Mbps. 13

14 It is applicable in TDD duplexing scheme. TECHNICAL OVERVIEW (continue)

 WIRELESS-LAN (W-LAN) Provides Superior bandwidth compare to any cellular technology i.e. 26MHz. Operates in 2.4 GHz ISM band. Uses DSSS (Direct sequence spread spectrum) technique to minimize interference Maximum bit rate is 11Mbps. 15

16 Coverage range is meters. It is also applicable in TDD duplexing scheme. TECHNICAL OVERVIEW (continue)

INTERFERENCE  The “co-channel interference” among the terminals of the same wireless access segment.  The “inter- segment interference” between terminals of different wireless networks.  The “cumulative interference” of all simultaneous active terminals with the aircraft avionics equipment.  The interference of the CMHN into terrestrial networks. 17

ADVANTAGES 1.The passengers of both business and economy could use their own wireless equipment. 2. 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 3. Their laptops have the software they are used to, the documents they need and with their personalized configuration (starting web site, bookmarks, address book). 4. Saving of the investment that would suppose the installation of terminals (screens, stations, and wired telephones) 18
