Propagation path loss-a comparison between ray-tracing approach and empirical models Abstract: The results obtained with a two-dimensional (2-D) propagation model for wireless communications in an urban environment are compared against the results of other propagation models, such as COST-231 Walfisch-Ikegami (1988, 1984), Hata's (1980), and Zhang's (1997).

Path loss can be defined as the ratio of the transmitted to received power, usually expressed in decibels. The equation for the Least Square (LS) regression analysis shows the path loss at distance d in the form PL(d)=PL(d0)+10nlog10 d d0 (1) where, d0 is the reference point at 1 km and n is known as the path loss exponent. The path loss values, PL(.) are expressed

6. Simplified path loss model: • Capture main characteristics of ray tracing using simplified model P r = P tK h d 0 d i γ, where K is a constant factor (P r(d 0)/P t), d 0 is a reference distance, and γ is the path loss exponent. • Path loss exponent is function of carrier frequency, environment, obstructions, etc. Typically ranges
