摘要
介绍了在地下空间无线通信领域所存在着的无源中继器通信技术以及研究其重要意义,分析了地铁中所使用的漏泄电缆系统损耗中耦合损耗的特性;重点用试验数据和图表介绍,在城市地铁项目(或地下隧道、矿井、地下指挥场所、人防工程等)无线通信系统中,在一定条件下使用无源中继器替代漏泄电缆实现地下空间场强覆盖的可行性和带来的经济效益。
The paper introduces the Passive Repeater Site communication technology in underground space wireless communication as well as its research significance, and analyzes the characteristics of coupling loss in system loss of leaky cable used in subway. The paper especially introduces visually, through experimental data, diagrams and tables, the feasibility and consequent economic benefit of using Passive Repeater Site instead of leaky cable under certain conditions to realize the underground space field intensity coverage in the wireless communication system of urban subway projects （or underground tunnels, mines, underground command sites and civil air defense engineering, etc. ）
