随着我国轨道交通事业的快速推进,无线通信技术将发挥越来越重要的作用。本文就是对无线覆盖这个当今轨道交通通信领域关注的焦点问题进行研究。在考虑速度因子和列控因子的基础上提出了一种新的小区覆盖半径的算法。该算法较全面的考虑了轨道交通运输环境下无线电波传播的路径损耗因素,包括快、慢衰落保护,高速保护、控制保护等,并对典型的移动终端进行了分析,计算得出了多种基站高度情况下的小区的覆盖半径。
With the rapid development of rail transit in our country, wireless communication technology will play an increasingly important role. This article is to focus on wireless coverage of the current focus of the field of rail transit communications research. Based on the consideration of speed factor and column control factor, a new cell coverage radius algorithm is proposed. The algorithm considers the path loss factors of radio wave propagation in the environment of rail transit more comprehensively, including fast and slow fading protection, high speed protection, control protection and so on. The typical mobile terminal is analyzed, Cell coverage radius at base station height.
