Wireless Network Planning And Design For Civil Aircraft

With the rapid development and popularization of wireless network technology, people have become increasingly inseparable from the network. As for the passengers within the aircraft isolated from network,the maximum vacuum up more than ten hours of network will bring considerable inconvenience to their work, entertainment and all aspects of life.The so-called "market should be born for need, and services should change for need".With the high competition in civil aviation,some airlines have found that "On-board Wifi" will bring new highlights to their service. It can be anticipated that the installation of wireless network equipment in the aircraft to meet passenger demand for Internet access should be the general trend.Firstly, with the analysis of the principles and characteristics of access to the Internet, and depending on the different models of aircraft to fly the different airlines,the most suitable and the most economical Internet access is chosen. Combined with the current and future mobile network technology, Internet access is ensured feasible and reliable.Secondly, the design of the interior cabin wireless network is considered the following aspects: efficiency, reliability, safety, electromagnetic compatibility,availability, airworthiness, etc. With the detailed analysis of the cabincomplex network environment,the safety and reliability of the aircraft has been designed,combined with the known wireless technology and network security technology.As the aircraft with multiple sets of communications and navigation equipment, it results in more complex radio environment.In order to ensure the cabin wireless network signals don't threaten to other electronic devices, the paper constructs models and simulates to quantify the impact of Wifi signal to other communications and navigation equipment.In addition, any equipment installed on civil aircraft should meet the requirements of the Civil Aviation Authority, which is also known as "airworthiness" of the device.To the wireless network on the plane, of course, also has its own Civil Aviation Authority airworthiness requirements.Through understanding the relevant regulations of the civil aviation, the wireless server should be linked with some sensors to obtain the necessary parameters to meet the "airworthiness." Finally, through market research results, combined with the characteristics of A330-200 aircraft, the wireless network system is detailed to construct to meet the needs of travelers and to design a series of security measures to prevent wireless networks from outside attacks and ensures its operation reliably.Innovation is mainly reflected on that the research of wireless network is in the background of civil aircraft and the research of electromagnetic compatibility in the civil aircraft specific wireless networkenvironment.On the other hand, with the author's resources and knowledge of the aircraft, the theory is applied to the practice. With the analysis of the example,finally the wireless network system is designed to work on the aircraft.
