既有铁路450 MHz无线列调改造GSM-R系统简析

Analysis of GSM-R Replacing 450MHz Train Dispatching Radio Communication for Existing Railways

结合既有铁路的特点,就平原区段和山区两种覆盖场景,从覆盖距离和投资两个方面对GSM-R系统宏基站、分布式基站、数字光纤直放站等无线设备的选择进行分析比较,并提出分布式基站产品改进建议。对既有铁路450 MHz无线列调改造GSM-R系统工程设计具有参考意义。

Combined with the characteristics of existing railways, the paper analyzes and compares the selection of the macro base station, distributed base station and digital optical fiber repeaters from covering distance and investment for plain section and mountain area, and proposes the improvement suggests of the distributed base station. The paper has reference for the engineering design of GSM-R replacing 450 MHz train dispatching radio communication for existing railways.
