  Abstract

A wireless communication is largely affected depending on employed frequency, height and distance of transmitting and receiving antennas, and obstacles such as mountains or buildings. Since line of sight(LOS) is not always established and propagation loss due to the obstacles occurs, accurate propagation loss prediction is needed to install the system appropriately.
This paper presents an algorithm which can be used to accurately predict the effect of diffraction in arbitrary shaped obstacles including oblique shapes using Fresnel's integrals instead of a knife-edge method. Then an algorithm was proposed for real hilly or mountainous areas and comparisons between proposed algorithm and knife-edge model was performed through computational simulations. For validity, measurements were performed using a base station for pes service operated in Korea. It is expected that proposed algorithm can predict signal strength precisely in hilly or mountainous area.
