Mobile communication network site planning and regional clustering

With the development of mobile communication technology, communication network planning in the site selection is more complex, in order to base stations to make reasonable planning can solve the problem of weak coverage area of the cover, this paper calculated the each existing base station site of two possible site type business ratios to determine the existing site is built acer station or micro base station, The proportion of macrobase stations and microbase stations is calculated by analytic hierarchy process (AHP). Finally, it is determined that 365 macrobase stations and 1109 microbase stations are built in the existing site, with a total cost of 4759 and a traffic coverage of 99.99%.Then, considering the cost and benefit factors, the optimization scheme eliminates 401 minimum revenue existing sites and uses particle swarm optimization algorithm to select 234 new sites to build microbase stations. 365 macrobase stations are built and 942 microbase stations are built, with a total cost of 4529 and a business coverage rate of 91.28%.
