摘 要:700 MHz作为移动通信的黄金频段,具有信号覆盖广、无线信号绕射能力强、穿透效果好的优点,适合大范围连续网络覆盖,是煤矿井下最佳频段。在5G建设上,采用5G-700 MHz组网可使用更少的基站数量达到相同的信号覆盖面积,大幅降低5G网络建设成本。在煤矿井下巷道场景下,5G信号覆盖距离相对传统的2.6、3.5 GHz频段提升约50%;在综采工作面场景下,700 MHz所需基站数为2.6 GHz的1/5、3.5 GHz的1/6。通过将5G-700 MHz网络与原有网络系统融合,实现了采煤工作面远程操控、综采工作面视频拼接、掘进设备远程操控等功能,实现了三元矿采掘工作面少人无人的目标。As the golden frequency band of mobile communication,700 MHz has the advantages of wide signal coverage,strong wireless signal diffraction ability and good penetration effect,which is suitable for large-scale continuous network coverage and is the best frequency band in coal mines.In 5G construction,using 5G-700 MHz networking can use fewer base stations to achieve the same signal coverage area,greatly reducing the cost of 5G network construction.In the coal mine tunnel scenario,the 5G signal coverage distance is about 50%higher than the traditional 2.6、3.5 GHz frequency band.In the fully-mechanized mining face scenario,the number of base stations required for 700 MHz is 1/5 of 2.6 GHz and 1/6 of 3.5 GHz.By integrating 5G-700 MHz network with the original network system,the functions of remote control of coal face,video splicing of fully mechanized mining face and remote control of mining equipment are realized,and the goal of fewer people and no one on the mining face of ternary mine is realized.
