云南喀斯特地貌无线网络覆盖

Yunnan karst landform wireless network coverage

针对云南喀斯特地形地貌无线网络覆盖困难、投资效益低的问题,本文提出网络建设优先级策略、制式选择策略和分层覆盖策略。根据网络流量、渠道分布、3G终端分布3个维度对不同网格进行评价并排出优先级,对不同优先级的网格实行不同建设策略,同时结合覆盖区域地形地貌、市场预期,细化各区域最优频段部署方案,必要场景实施分层覆盖,在确保快速提升云南喀斯特地貌无线网络覆盖的同时,保证投资效益。

The karst landform features brings about many problems to network construction in Yunnan,such as the diffi culty in wireless network coverage and low investment efficiency.In allusion to such problems,the thesis proposes propriety strategy,system selection strategy and layered coverage strategy for network construction.Firstly,the thesis assesses and ranks the priorities of different grids from three dimensions including network flow,channel distribution and 3G terminal distribution.Then,it presents different construction strategies in accordance with different priorities.Meanwhile,based on the geomorphic features of the covering regions and market expectations,the thesis also elaborates the deployment schemes of the optimal frequency bands for each region and proposes to implement layered coverage in necessary scenes.The purpose is to guarantee the investment efficiency while increasing the coverage of wireless network in the regions of Yunnan featured with karst landforms.
