摘要

日本正在开发各种飞机宽带通信系统。一种是用于地震、洪水等灾害的救援和支持,也用于地面监视、土地测量等。另一种是针对客舱内无处不在的无线环境,如手机、客机无线局域网等。研制了Ka波段宽带通信系统机载设备,并利用齐柏林NT飞艇进行了高清视频传输、电视电话、IP电话、远程IP摄像机监控等测试。结果表明,Ka波段100元数字波束形成天线为地面提供81个固定小区,每个波束的传输速率为50mbps。目前,我们正在研制飞机与地面之间的48ghz宽带通信系统。预计将在日本国内客机上实现CBB(波音连接)系统的替代。我们在回声室测试中获得了100mbps的传输速率,并计划明年在Jet飞机上进行测试。

Research and Development on the Broadband Communication System for Airplane using Millimeter-Wavelength Band
Various broadband communication systems for airplane are under development in Japan. One is for rescue and support on disaster such as earthquakes, floods and also for ground surveillance, land measurement and so on. Another is for in-cabin ubiquitous wireless environment such as mobile phone, wireless LAN for passenger airplane. We have developed on-board equipment on broadband communication system in Ka band, and carried out the test of high definition video transmission, TV phone, IP phone, remote IP camera monitoring by using Zeppelin NT airship. We got the results that 100 elements digital beam forming antenna in Ka band gave 81 fixed cells on the ground and each beam had 50 Mbps transmission rate. And we are now developing broadband communication system in 48 GHz band between airplane and ground. Those are anticipated in realize substitution for CBB (Connection by Boeing) system in Japanese domestic airliner. We got 100 Mbps transmission rate in an echoic chamber test and have the plan to test using Jet plane next year.
