Abstract
This work presents a comparison between multiple-building forward diffraction loss predicted in urban areas when considering a plane-wave incidence over the rooftops, and when assuming the wavefront impinging on the array of buildings to be spherical. The mentioned comparison is carried out through two hybrid uniform theory of diffraction-physical optics (UTD-PO) solutions, and is intended to clarify the validity of each assumption in a typical urban environment. Results can be used to achieve a more accurate and realistic planning of radio communication systems
