This paper deals with an impact of atmospheric conditions on the speech quality in the GSM. We found out a correlation between weather conditions and the speech quality. The GSM technology is the most widely utilized communication standard which it is now coming to its bandwidth limitation especially in big cities and densely populated areas. Under such circumstances, even a minor weather change and rain could be a decisive factor causing changes in the quality of service. We have obtained both meteorological data and Mean Opinion Score value specifying the current speech quality in the GSM network. Those data are evaluated and compiled via statistical methods, whose accomplishment is dataset competent to be utilized by more advanced data mining methods. According to space distribution and fragmentation, our team has chosen set of suitable methods used to find data-mining, data analysis and correlation. As a computation result, our team found out the correlation between current rain density and the speech quality. Results from the MOS tests are reported, and an analysis of the obtained speech samples is presented. Outcomes are summarized and potential further directions for the continuation of research are discussed.
