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. Communication signals of three GSM networks serving in Turkey were received from mobile phone through a developed program, a data base was created and the assessments have been made on this data on base of a frequency analysis. Assessments of the 100 data obtained separately for each GSM network from 100 stable points through the nearly 20 km a way between Gazi University Central Campus and 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 between Network A and the other networks have emerged. Network A was followed by Network B and C with the radios of 39% and 28%. In terms of the stability of signal, Network C has been the most stable network. It is proven 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.
