| With the rapid development of mobile Internet,LTE(Long Term Evolution,long-term evolution technology)as 3GPP long-term evolution technology has made a breakthrough.LTE network in recent years,the official business,with its low latency,high speed for domestic users to provide high-speed,convenient mobile data network services features,by the user favorite and get more and more attention of operators.LTE network is still in the planning and optimization stage,according to its network characteristics and construction methods,how to do LTE network planning,rapid optimization of network performance is the key to building a boutique LTE network.In this thesis,firstly,we start with the introduction of the technical characteristic and the network structure of LTE,analysis the differences and similarities of 2G,3G and LTE wireless network planning and optimization.summarize the characteristic and flow of LTE wireless network planning and network optimization combining with the methods of 2G,3G wireless network planning and optimization.Thenwith the help of the simulation we analysis the key parameters effecting on coverage and system capacityin LTE radio network planning and network optimization,including uplinkbudget and downlink budget,the relationship between the edge rate and the cell coverage,and contrast with the WCDMA wireless network coverage,analysis the relationship between LTE capacity and system parameters,estimate and analysis the users of Vo IP.Finally,we illustrate the co-location interference between FDD-LTE and TD-LTE,mainly including spurious interference and adiacent channel interference and give the relationship between the co-location interference and the distance between the transmitter and the receiver and the filter's attenuation characteristic based on using the antenna seperation scheme.The study of this thesis will make beneficial exploration for the future construction and planning of LTE network and provide the academic instruction. |
