Improved COST 231-WI Model for Irregular Built-Up Areas

The estimation of the field levels generated by radio base stations set in urban environment is still urgent need and a relevant issue for the compliance to national regulations and for propagation concerns. This work copes with the estimation of electromagnetic field generated by UHF base stations in peculiar urban scenarios. To account for irregular geometries and to deal with the propagation in hilly town, the COST 231-Walfisch-Ikegami model is modified and rephrased in order to evaluate the path loss at distances greater than 20 meters from the base station in such peculiar urban environments. Measurements were carried out in the small urban and irregular built-up areas of Dorgali (NU), Cala Gonone (NU) and Lunamatrona (CA), Italy, to validate the model.
