Statistical characteristics of radio waves field in office room

The paper presents the results of an experimental study of the electromagnetic field (EMF) levels inside a multi-storey office building. Histograms of Cartesian orthogonal components, modules, and spherical angular characteristics of the electric and magnetic field strength vectors are presented. The Rode & Schwarz spectrum analyzer FS300 is used as a measuring instrument equipped with small vibrator and loop antennas. The measurements were carried out at frequencies of 49,75 MHz and 56,25 MHz and heights of 1 and 1,7 m and the observation point was located above the floor of a rectangular room of 48 square metres. The data obtained can be used as a basis for solving a wide range of applied problems with statistical simulation method: from ensuring the safety of EMF-based workplaces to creating EMF-channels for leaking of confidential data.
