Abstract: By the research of sampling survey and radio propagation,a novel method on sampling and analysis of field test data is introduced.According to the theory of sampling survey,cluster analysis is introduced to finish the sort.Then a method on analysis of field test is presented by using cluster sawpling and two-stage sawpling.In order to improve the reliability of field test data,by the estimation theory of sample size,a method of field test route choice is introduced based on wireless network planning.
