Propagation loses within urban areas

Operators of accessing networks are interested in solutions related to the wave propagation models within built areas that can precisely define the signal level received by the subscriber accessing station for a selected propagation scenario. In the paper is presented new multi-variant empiric model (MEM). The presented model takes into account the average height of the terrain development. In order to determine the signal level at the reception site the MATLAB application was developed, where selected popular propagation models LOS and NLOS were implemented to compare them with the MEM model. In the paper the simulation results are presented.
