摘要: 随着地面网络快速发展以及航空出行逐渐大众化,民用飞机乘客对乘机过程中联网的需求日益强烈。文中从机上联网背景出发,围绕乘客需求、机上联网市场与发展现状出发分析机上联网的必要性。聚焦于机上联网技术发展,发现机上空中互联技术正在从Ku向Ka和高通量Ku演进。针对机上联网的卫星网络接入和机载Wi-Fi软硬件设备以及服务两项关键技术以及应用情况展开分析,分析发现美国在机上联网技术方面相对成熟,Ka以及高通量Ku技术发展仍以美国和欧洲为主,国内实现机上联网全国产化仍需加强两项机载关键技术的投入。机上联网具有很长的产业链,对产业链上的企业来讲既是机会也是挑战。最后从乘客需求、航空公司、第三方服务商以及适航4方面分析了机上联网带来的机遇和挑战。
