                         propagation problems in wide area networks for wireless 
                         communications. Spring adds to an especial designed propagation 
                         program represents a powerful way to perform coverage studies in 
                         wireless network communications. The method presented here was 
                         developed to avoid the high cost and complexity of non free 
                         softwares. Spring is not a specific program to work with 
                         telecommunication problems. In this way, was necessary to create a 
                         program to get from and pass to information to the spring in an 
                         interactive mode. The special designed program imports 
                         geoprocessing data from the spring for a target area. The results 
                         from the propagation program are exported to the spring to 
                         evaluate the coverage using a specific propagation model. This is 
                         a low cost method to study the performance of different 
                         propagation models in the wireless coverage analysis. To reduce 
                         the development cost we decided to use only free programing tools 
                         as Octave. Octave is a free version of Matlab (is not equal) that 
                         works in a similar way and run under Linux. The Linux was our 
                         choice as development platform. An application for WiMax network 
                         was carried out to evaluate the coverage area over a small region 
                         in Brazil. The results showed that the technique proposed here is 
                         able to perform well coverage prediction for wireless 
                         communication.",
