Detailed Description

the ITU-R 1411 NLOS over rooftop propagation model

This class implements the ITU-R 1411 LOS propagation model for Non-Line-of-Sight (NLoS) short range outdoor communication over rooftops in the frequency range 300 MHz to 100 GHz. For more information about the model, please see the propagation module documentation in .rst format.
