In this paper

a GSM network coverage optimization system is developed in visual C++ development environment

which is based on the COST-231 and hata models

and fits for various kinds of communication environment. The paper outlines the design of system and the implementation of algorithm

detailedly discusses the programming implementation process of downward inclination and pitching angle that was seldom discussed about

implements the automation of coverage regions optimization detecting

emulating

analyzing and optimizing

solves the coverage problem of precise evaluating in GSM network environment

and achieve the goal to optimize the GMS network.
