Experimental Propagation Study for 2G, 3G, and 4G Frequencies

Nowadays, there has been an increase and dependent items that affect the quality of the signals such as the properties of substances in the buildings, objects and humans' movements, electronic equipment. In this study, the effects of electromagnetic interference on the functional usage of mobile communications are examined. The indoor and outdoor attenuation characteristics of 2G, 3G and 4G frequency bands are investigated. Field strength measurements are conducted in university campusopenarea, along a corridorfield in a fivestoreyuniversitybuilding, in different floors, and rooms, where normal incidence on plane boundary is of main concern. This study investigates multilayer model for building structures. The evaluation of measured values together with the simulated results is compared with literature outcomes. In addition, dependency with the frequency, power of the waves and existence of trees on the transmission path are also discussed.
