¿µ¹®³»¿ë¿ä¾à | The standard is based on measurements made by several countries working jointly. It analyzes the wireless service using the range of 0.8 ~ 73 §× in the urban area and interference with other wireless services in the same band or adjacent band provides a formula that can predict the required path loss in advance. The propagation model does not require any conditions other than the urban environment, and distinguishes between line of sight and non line of sight paths. Furthermore, the model is limited to the case where the height of the transmission / reception position is lower than the surrounding buildings. | ||
