Planning Of Local Transport Network Of XianNing

This thesis investigates the radio access network technology of WCDMA, which is one of the3G standards. The local transport network planning for WCDMA is discussed, and the planning for local transport network of Xianning network has been done.The architecture, standard, and networking schemes have been investigated. The key technologies, such as STTD, beamforming, diversity reception, transmit diversity, are discused. The evolution of WCDMA is also presented.The planning of local transport network for WCDMA is discussed, the overall construction strategy is proposed. The distribution coverage scheme is also discussed.Lastly we focus on the planning for2013to2015year Xianning WCDMA local transport network. The inner and outer environments of WCDMA related are investigated based on the current status and problems existed. The overall development route map and object are proposed. The design and planning for radio access network, core network, service platform, and transmission network of WCDMA are investigated in detail. Making a brief analysis of local transport network of Xianning Unicom and considering the shortcomings of current networks, we put forward the targets and principles of the network optimization, and presented the concrete measures and guiding ideology for the choice of technologies and equipments in the course of network optimization. At the end of this thesis, we described the concrete optimization scheme of local transport network of Xianning Unicom.
