摘 要:设计了一款基于5G技术的消防Mesh专网通信基站,基于双向OFDM传输技术、载波聚合、无线感知抗干扰、混合场景下路由算法等关键技术,在不提高基站发射功率的前提下,增大网络通信速率,扩大传输距离,提高抗干扰性能,并进行了实验室环境下网络性能测试和外场应用测试。试验结果表明,专网基站最大通信带宽可达100 Mbps,基站点对点传输距离可达80 km以上,可有效避免同频段其他无用信号的干扰,多跳组网后仍具备较高的数据传输能力且时延与双跳组网基本一致,该基站可以作为数字化战场的核心通信节点,解决传统Mesh设备和技术面临的难题。A fire mesh dedicated network communication base station based on 5G technology has been designed,which uses key technologies such as bidirectional OFDM transmission technology,carrier aggregation,wireless sensing anti-interference,and routing algorithms in mixed scenarios.Without increasing the transmission power of the base station,the network communication rate is increased,the transmission distance is expanded,and the anti-interference performance is improved.Network performance testing and field application testing have been conducted in laboratory environments.The experimental results show that the maximum communication bandwidth of private network base stations can reach 100 Mbps,and the point-to-point transmission distance of base stations can reach more than 80 km,effectively avoiding interference from other useless signals in the same frequency band.After multi hop networking,the base station still has high data transmission ability and the delay is basically the same as that of dual hop networking.This base station can serve as the core communication node of the digital battlefield,solving the problems faced by traditional Mesh equipment and technology.
