以胶济客运专线(高密段)的覆盖方案为例,通过理论分析和现场模拟测试,验证了市区段高铁采用DCS1800覆盖的可行性,提出了高铁覆盖GSM&DCS混合组网方案。其中在郊区路段采用GSM900进行专网覆盖,市区路段引入DCS1800进行专网覆盖。
It describes an example of the passenger line in Ji＇nan-Qingdao high speed railway coverage solution, verifies the feasibility of using DCS1800 in urban area. It presents the GSM＆DCS hybrid network solution for high speed railway coverage. GSM system is used in suburb area and DCS system is used in urban area.
