摘要
在地下矿井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工业、科学、医学 (ISM)频段 (86 8MHz～ 91 5MHz)较合理。这样也有利于与地面移动通信系统兼容以及利用现有的技术成果。另一个使用ISM频段的原因是考虑到该频段天线尺寸和设备体积远小于高、中。
The mine is a complex space in which wireless communication is different from that of free space. Basing on the knowledge of how geology environment influences the selection of communication frequency in the mine, this paper also considers the size of the mobile equipment and determines the relatively good frequency band (868 MHz～915MHz) for wireless communication transmission in the pit. It is compatible to the mobile communication system on the ground and can use existing technology. At the same time, this paper provids the location scheme for mine cellular communication base station.
