Paper Title
Propagation Study of GSM Frequencies through Forest

Abstract
Abstract - This study investigates the attenuation characteristics of GSM (2G, 3G, and 4G) frequencies, which is important for the determination of coverage areas in the forest. Some theoretical models from the literature were studied and simulated. The loss and electrical field of the transmitted signal were measured in the woodland of Sakarya. Our results were compared with the literature and experimental datagood agreement was found. Keywords - Attenuation, GSM, Propagation Models,Coverage areas.
