摘　　要：主要研究航空无线宽带通信系统的无线网络信号覆盖(无线接入网)问题。提出了三种无线信号覆盖模型:地面基站信号覆盖模型、卫星中继信号覆盖模型、高空平台通信系统(HAPS)覆盖模型。然后从建设成本、技术难点、覆盖效果等角度综合分析了各个模型的优缺点。最后得到以下结论及建议:地面基站信号覆盖模型技术成熟,但是建设成本高,比较适合机场及繁忙的航线航路;卫星中继信号覆盖模型建设成本低廉,但是传输数据速率低,难以满足宽带通信要求,这种模型比较适合跨洋航线、非繁忙航线以及临时航线;HAPS(高空平台通信系统)模型覆盖范围广、工程造价低,但是技术不够成熟,因此可以作为未来航空宽带通信信号覆盖技术的选择。To study the aviation wireless broadband communication system wireless network signal coverage （radio access network） problem, three wireless signal coverage models are put forward., base station aviation communication coverage model, satellite relay aviation communication coverage model and HAPS aviation communication coverage model. The above three models are compared and analyzed from the aspects of construction cost, technical difficulties and covering effect. The following conclusion suggests that： base station aviation communication coverage model is mature but with high construction cost, mainly suitable for airport and busy route; satellite relay aviation communication coverage model is cheaper but with low data transmission rate, accordingly incapable to meet the requirement of broadband communication and suitable for transoceanic route, off-peak route and temporary route; HAPS covers a widest range with lower cost, but this technology is not mature enough, which can be applied in future aviation broadband communication signal covering technology.
