Analysis of Mobile Communication Signals With Frequency Analysis Method

In this study, mobile communication signals accessed by users were measured and the signal strength performances of GSM networks were evaluated. Through a developed program, communication signals of three GSM networks serving in Turkey were received from mobile phone and a data base was created. The assessments have been made on this data on base of a frequency analysis. Assessments of the 100 data obtained separately from each GSM network from 100 stable points through a way nearly 20 km a way from Gazi University Central Campus to Gölbaşı Campus were showed that; Network A has been the best signal strength performing with 83 % well-signal ratio in 3 networks and a significant class difference among Network A and the other networks has been observed. Network A was followed by Network B and C with the ratios of 39 % and 28 % respectively. In terms of the stability of signal, Network C has been the most stable network. It is proved that although the companies providing mobile communication services announce their widespread coverage area, the signal strength levels accessed by users show significant differences among the networks
