Abstract: With the development of ground internet and the popularization of travel by flying,the passengers urgently want to surf the internet during flight.In this paper,based on the background of interconnection onboard,the necessity is discussed from three facts including requirement of passengers,interconnection onboard market and current application status.Focused on the development of satellite communications,it is found that the satellite broadband develops from brand Ku to brand Ka and brand HTS Ku (High Throughput Satellite).The analysis is carried out on the key technologies of interconnection onboard,and the results show that the technologies of satellite communications specially on the brand Ka and HTS Ku in USA and European are more mature.In order to realize the national production of interconnection onboard,it is necessary to increase investment in above two key technologies.The industry chain of onboard web interconnection is complex and long,it's not only an opportunity but also a challenge for the companies of the industry chain.Accordingly,the requirement of passenger,airlines,the third party service provider and airworthiness are concluded in this paper.

Key words: Onboard devices, Onboard web-interconnection, Opportunity and challenge, Passenger demand, Satellite communication
