摘要
国家高度重视应急通信网络的规划与建设,特别是无人机的应急通信技术研究越来越受到重视,相对于4G“尽力而为”的网络特性,5G凭借大带宽、低时延和高可靠性的网络能力,为网络性能配置提供了灵活的配置空间,将会逐步成为满足应急通信不同场景需求的首选技术。提出了基于固定翼式无人机的5G应急通信覆盖解决方案,该方案通过无人机机载5G一体化基站,结合地面宏基站辅助实现组网。对无人机基站下行覆盖与回传链路预算进行仿真,结果表明,所提出的解决方案可以满足偏远地区和应急通信的覆盖需求。
Country attaches great importance to the planning and construction of emergency communication network,especially with more attention paid to the UAV(Unmanned Aerial Vehicle)emergency communication technology research.Relative to the 4G network characteristics of the"Try best",5G with large bandwidth,low latency and high reliability of network capacity,provides a flexible configuration space for performance of a network configuration,and will gradually become the preferred technology meet the demand of emergency communication different scenarios.UAV is proposed in this paper,based on fixed wing type 5G of emergency communication coverage solution.The solution achieves network through the integration of UAV airborne 5G base stations,combined with ground acer station auxiliary.UAV base station downlink coverage and back link budget are simulated,the results show that the proposed solution can meet the demand of remote areas and emergency communication coverage.
