Propagation study of GSM power in two dimensions in indoor environments part 1

Abstract

This article is based on the application of an experimental system to measure the power of an electric field in indoor environments. A robotic system is used to position automatically an antenna in a fixed grid within an environment. The collected data is processed, analyzed and demonstrated graphically in order to explain the 2D and 3D pattern of the electric power signal. Finally, a concrete environment is studied and the measured data evaluated in order to characterize the electric field radiated by a GSM base station and to analyze the impact on the human body. The results show that the measured signals have space and temporal variability in a concrete point of their propagation, which produces slow and fast variations with the distance.
