【摘要或目录】：随着GSM2R 网络在中国铁路的广泛应用, 网络预规划作为网络建设的一个重要步骤, 得
到了重视。结合铁路通信的特点, 在高速和普速环境下, 采用Hata 模型对典型的5 种地理环境
进行建模, 并结合链路平衡预算, 给出小区覆盖半径的规划方法, 同时, 利用同频干扰与小区重
叠区的关系, 给出小区重叠区的规划方法。

Abstract : Wit h broad application of GSM2R network in Chinese railways , calculation of network
coverage at t ract s considerable at tention as an important step in network planning. According to
t he characteristics of communication in railway and respectively in conditions of high speed and
common speed , five typical railway environment s are modeled by means of Hata model . Toget h2
er with t he link balance budget , the paper gives t he met hod of calculating cell radius. Meanwhile ,
wit h t he relation between co2channel interference and overlaid region , t he paper int roduces t he
calculation met hod of overlaid region extent .
Key words : Hata model , Coverage radius , Link budget , Overlaid region
