Using COST 231: Extended Walfisch-Ikegami Model

The hybrid urban/indoor 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.

In this case, the transmitter is not very high, so we expect lower accuracy. Also, any time the dominant path is not purely in the vertical plane, this method will under-estimate the received fields, but it will be faster in comparison to the dominant path model.
