Analysis of radio wave propagation for a specific metro station

In this thesis, radio propagation areas at Umitkoy and Inonu Neighborhood metro stations were analyzed at different distances and surfaces. At the same time, path losses in the radio propagation area were investigated. Studies have been carried out on the modeling of wireless coverage area in subway stations that vary in different distances and conditions. The theoretical calculations with empirical formulas were also controlled by measurements on the existing subway station in the field. As a result of the losses observed depending on the ambient conditions, the material used and the installation points, a method has been developed to enable optimization before the installation. The path loss was calculated using the codes written in the MATLAB program and the graphics were drawn according to the modeling type. The theoretical results and analyzes were compared with the field measurements and the error rate was obtained. In accordance with the observed and calculated results, necessary arrangements were made for the optimization studies and the ideal design for the radio coverage area was avoided, preventing the problems of non-reception and unnecessary material usage.
