Study and simulation of outdoor propagation models in wireless communications system / Kamariah Ab Kadir

Propagation loss prediction models play a very important role in the design of cellular mobile radio communication systems [2]. Radio transmission in a mobile communications system often takes place over irregular terrain [1]. Therefore, outdoor propagation models are important to predict the path (...

Mobile communication systems. Access control Radio Propagation loss prediction models play a very important role in the design of cellular mobile radio communication systems [2]. Radio transmission in a mobile communications system often takes place over irregular terrain [1]. Therefore, outdoor propagation models are important to predict the path (signal) loss. These models can be classified into theoretical and experimental models. The main experimental models are the Hata-Okumura, and COST231-Hata model. The problem of these models is that these prediction expressions are based on the qualitative propagation environments such as urban, suburban, and open (rural) areas [11]. The performance and applicability in those environments were investigated and discussed. The COST231 -Walfisch-Ikegami model (COST231-WI) is a result of the effort to use a quantitative description of the propagation environments [11]. In addition to the height of transmitter and receiver antennas, the building's profile and street width are considered in this model [6]. For the more quantitative understanding of the propagation environment, the path losses of Hata- Okumura and COST231-Hata are compared with those of COST231-WI based on the same frequency, base station (BS) and mobile station (MS) antenna heights, but changing building height and street width. The impact of these parameters is presented.
