摘　　要：指出了机间数据链的重要性,阐述了低传输延迟特性、高数据传输率、低截获率、高抗干扰能力、动态组网等特征对系统的要求。对频率选择、窄带多波束天线设计、信道接入协议等核心问题进行了较深入的分析,指出了解决方案和途径,并讨论了建立网络协议开发平台的意义及方法。The importance of Intra-flight Data Link （IFDL） is pointed out. The features of IFDL are expatiated including low transferring delay, low probability of detecting （LPD） and low probability of interfering （LPI）, etc. The all - important problems such as frequency selection, narrow beam antenna design and channel access protocol implementation are discussed. The schemes or approaches are provided. The significance of building platforms for developing wireless network protocols is mentioned and the techniques are put forward as well.
