The COST 231 model [1-2] is a semi-empirical path loss model, resulting from the combination of Walfisch-Bertoni [3] and Ikegami [4] models. It is recommended for macro-cells in urban and suburban scenarios, showing very good results for path loss calculations for base station antennas located above the average roof height. However, the prediction errors increase significantly as transmitter antenna height approaches the roof height, reaching a very poor performance for transmitters located below that level. The COST 231 model has a frequency range between 800 MHz to 2000 MHz. Compared to previous models such as Okumura-Hata, the calculation procedure is more detailed, and includes four additional parameters, namely: • height of buildings • width of the roads • building separation • road orientation with respect to the direct radio path. The basic propagation loss, Lb, is calculated as the sum of three components: the free-space loss, L0, the roof-to-street loss, Lrts, produced in the street where the receiver is located, as result of the diffraction on the next rooftop; and the multiscreen diffraction loss, Lmsd, produced by multiple diffractions on the building rooftops along the direct propagation path. The model also distinguishes LOS and NLOS situations.
