The urban database is solved using the COST 231 - extended Walfisch-Ikegami model.
This method is suited for high transmitters in urban scenarios when the dominant path
is expected to be in the vertical plane over rooftops, followed by diffraction down
into the street.

Model.
A wave that is guided along a street between buildings would not be included.
Simulations using COST 231 - extended Walfisch-Ikegami model tends to be fast.
