there are three important subsystems in internet in-flight,they are
1.Ground to aircraft link: It establish the connection between Internet Service Provider (ISP) and the aircraft . It can be employed by direct ground RF link or satellite . This block can be removed if only entertainment services like video and audio broadcasting are to be offered by a company
2..Network distribution: Optical fiber is expected to be used in the future but in present shielded twisted pair cables are the mostly used inside the aircraft.
User link: With the aim of reducing the amount of needed cable, a wireless link seems to be an optimal solution. This work focuses on this subsystem.
