This article provides a network optimization analysis and evaluation method based on swept frequency data.It mainly uses quadrant coordinates to classify sample data according to statistical indicators for analysis and evaluation scenarios

which helps to improve massive data in daily and special network optimization work.The analysis efficiency

visually presents network indicators and value data（regions）

and also has high value in the analysis of network layer relationship across standards and frequency bands.At the same time

this method can also be used for post-evaluation of actual results of network planning and simulation.It is conducive to the accumulation of experience in planning and simulation

and continuously improves the accuracy of the plan.
