The Project Construction Of Fujian's GSM Network Railway System Plan And Application

As wireless network development show itself continuous improvement and quality upgrading, users of network put forward higher and higher requirements about the wireless network coverage and quality. At present, China continuously rapid development of transportation, the high-speed railway coverage have more problems to appear on the actual network construction.To solve these problems, the author take part in the Ningde and Luoyuan section of the railway GSM network planning, mainly uses the distributed base station to a total cell networking, the introduction of a total plot of the RRU, you can effectively reduce the switching frequency, to improve high-speed rail network security and stability. And using a layer by layer network to cover and protect the public network outside the railway station, composed of chain-shaped cell layer, covering more high-speed railway users, the rest of base stations that make up normal the non-train customer service cell, high-speed rail cover layer and the non-train customer service cell is not independent and interrelated. To solve the railway abnormal situation, such as temporary parking and so on.The present paper mainly aims at the author charged in planning FuWen railway GSM network project construction, to the GSM basic principle, the network characteristic, the network planning theory knowledge, the research, and the union project practice to the network planning, the design proposal for different application, the project construction situation and so on.three aspects to carry on the introduction, simultaneously the author refers to the network planning method based on the community RRU, which makes the communication network in bullet train steady and reliable.
