摘要
随着GSM-R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。
With broad application of GSM-R network in Chinese railways, calculation of network coverage attracts considerable attention as an important step in network planning. According to the characteristics of communication in railway and respectively in conditions of high speed and common speed, five typical railway environments are modeled by means of Hata model. Together with the link balance budget, the paper gives the method of calculating cell radius. Meanwhile, with the relation between co-channel interference and overlaid region, the paper introduces the calculation method of overlaid region extent.
