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.

How to add site
How to add transmitter • Repeat the same process as site • Make sure the conditions: data should be in same format of atoll template Antenna should be selected Antenna height should be selected Propagation module should be selected
Coverage calculation • Group the site and transmitter as per requirement • Activate the antenna • Select Filtering Zone/Focus Zone/Computation Zone as per requirement
