ABSTRACT

In the future, airliners will provide a variety of entertainment and

communications equipment to the passenger. Since people are becoming more and more

used to their own communications equipment, such as mobile phones and laptops with

Internet connection, either through a network interface card or dial-in access through

modems, business travelers will soon be demanding wireless access to communication

services. Specifically it focuses on wireless services such as UMTS and W-LAN in

aircraft cabins that connect the passenger via satellite to terrestrial infrastructure. Current

trends are towards high data rate communication services, in particular internet

applications. In an aeronautical scenario global coverage is essential for providing

continuous service. Therefore satellite communication became indispensable, and

together with ever increasing data rate requirements of applications, aeronautical satellite

communication meets an expensive market. Certain features of UMTS and W-LAN that

helps to provide these services are also explained.
