摘要
论述了高速铁路GSM-R系统中无线覆盖技术要求,并针对哈大高速铁路中无线通信系统的弱场问题,提出光纤直放站、泄漏电缆等覆盖技术,以解决路堑、隧道等多种地形的弱场实施方案。
The paper discusses the wireless coverage technical requirements of the GSM-R system. For the weak field intensity problem of the wireless communication system for Harbin-Dalian high-speed railway, it puts forward to use repeaters and leaky cables for solving the weak field intensity problem in road cuttings and tunnels etc.
