چکیده
This paper presents an explicit formula for propagation path loss prediction of microcellular communication in an urban street scene. The formula is derived based on geometrical optics and diffraction theory and it takes into account multiple reflections along main streets, side streets and diffractions around corners. Comparisons between our theoretical results with measurements and ray tracing model results in New York city and Tokyo show good agreement.

In this paper, to model the path-loss characteristics in urban line-ofsight(LOS) propagation, we performed measurements in Goyang, Republic of Korea, at a frequency of 2.4GHz using the IEEE 802.15.4 standard. Although path-loss variance for any street existed, measurements yielded a typical pathloss of PL(dB) = L r ) ( log 10 10 , where is the path-loss coefficient, r is the street le...

A Statistical-Sakagami model is proposed by using multiple regression formula for path loss prediction in urban and sub urban area. It is assumed that the three main parameters: hB, W and α are not deterministic variables like those in theory propagation models, but statistical variables, and all the three parameters are varying at the same time in the simulation. The performance of the formula...
