Abstract
With the rapid development of mobile communication, users’requirements for mobile communication are increasingly high. Urban viaducts, as important intersections in urban traffic, are key points and difficulties in coverage. The problems of coverage for urban viaducts are mainly weak and messy signals as well as high call drop rate. According to this situation, the ideas and methods for coverage are introduced. Combined with the coverage case for Dinghui Bridge, specific analyses are carried out. By combining optimization with construction, reasonably controlling coverage areas of service cells, and trying to reach common LAC, RNC and frequency, a relatively ideal condition can be achieved.关键词
