Add propagation Module

Go to module tab in explorer window

select SPM

Make duplicate of SPM

Double click the duplicate SPM

Give some special name for duplicate propagation module in general tab

Add propagation Module

Change the value of K1,K2..K7 in parameter tab

Change the value of clutter parameter in clutter tab

Add propagation Module

We can add different propagation module as per requirement.

Value of constant parameter K1,K2 K7 is calibrated by module tuning of the Network

The Standard Propagation Model is a propagation model based on the Hata formulas and is suited for predictions in the 150 to 3500 MHz band over long distances (from one to 20 km). It is best suited to GSM 900/1800, UMTS, and CDMA2000 radio technologies.
