摘要
在介绍了井下地质和生产环境对通信频率影响的基础上,考虑到移动设备的体积,确定井下无线通信传输在ISM频段(868-915 MHz)较合理。这有利于与地面移动通信系统兼容和利用现有的技术成果,同时提供了井下蜂窝通信基站的布置方案。
Based on the introduction of factor foundation that geology environment influence communication frequency in the mine. This paper have considered the volume of the mobile equipment and defined the relatively good frequency channel (868 MHz -915 MHz) of the wireless communication transmission in the pit. This is propitious to compatibility of the mobile communication system in the ground and using existed achievements. At the same time, this paper provided the disposal scheme for mine cellular communication datum station.
