The aim of this article is to make a detailed analysis of the influence of the reinforcement diameter, the number of rows of reinforcing bars and the spacing between them for the values of the electric field intensity. The subject of the research is a model containing a wall made of concrete (dielectric) and reinforcement (conductor). Four reinforcement systems commonly used in building construction have been analysed. In addition, the influence of symmetry and asymmetry in the structure of bars on the values of field intensity determined for non-homogeneous material structures (reinforced concrete) was considered. For comparison, a concrete wall, without reinforcement (homogeneous material) was also analysed. Using FDTD method, the maximum electric field values generated by the Wi-Fi operating at the f = 2.4 GHz were calculated.
