Research On Airport Area Mobile Communication Multi-Network Coverage

At present with the constant change of the wireless communication development,users of mobile communication network in different environment quality put forward more and more,the wireless communication market demand,is witnessing profound changes in the past to technology as the guide of mobile communication network is heading for different types of user demand oriented development of private network coverage solutions.MIIT post for operators to take infrastructure co-construction and sharing base station,but also on day feed sharing way is very backward,so build up a indoor distribution platform at the same time carrying a variety of network systems,by network operators signal multiplexing way more,make all base stations in the network share a day feed system,to replace the original network operators to repeat more covered more,avoid redundant construction,shorten the construction period,and effectively reduce the cost of network maintenance.In this papers,based on the research of wireless network optimization technology,network technology as the research direction for the airport,the airport passengers and staff demand for mobile communication network,careful analysis such as the environmental characteristics of the airport scene signal coverage,day feed design,source and structure of road,passive components selection,system networking,signal distribution,signal interference and capacity allocation strategy all sorts of factors,such as multiple network system design of the airport has carried on the thorough discussion.The system capacity configuration and interference suppression in airport wireless coverage technology are studied and analyzed in detail.The system capacity allocation problem is decomposed into capacity planning,switching logic and reveal the three problems,first by capacity prediction algorithm to forecast the system capacity,and then establishing reasonable partition reduce district switch signal,finally by capping the antenna signal in the output power of strictly limited in indoor,good solve the problem of the capacity allocation.The system interference can be divided into three types: spurious interference,intermodulation interference and blocking interference.By calculating the frequency of intermodulation interference,avoid the working frequency of base station which may cause intermodulation interference.The isolation algorithm is used to optimize device selection to suppress blocking interference.Completion of theory study,by Kunming Changshui airport network coverage project case is verified,the experiment results on interference suppression and covering effect is very ideal,the actual case of feedback results support the conclusion of theory research,in fact,so on the basis of this paper in the same application scenarios more general solution and analysis method of network coverage.
