Overview of Wireless Avionics Intra-communication Network Technology

Abstract

The wireless avionics communication technology in the civil aircraft will be an important technology for the development of the next generation aircraft, which can further reduce the weight of the aircraft, enhance the safety of the aircraft, and improve the operation economy of the civil aircraft. This paper describes the definition of wireless avionics intra-communication (WAIC) network, summarizes the research status of WAIC network at home and abroad, analyses the characteristics of WAIC network, and gives the key technologies, such as network architecture, time synchronization, network management, network security and hardware design in the process of WAIC network design. It also puts forward the technology path for realization of 4.2~4.4 GHz wireless communication based on software defined radio in WAIC network.
