Many thanks for the discussion, I understand your way, but If i go to your way it means , I should consider Carried traffic & do reverse engineering to get TRX needed.
But in this way i am getting cells with 100% Voice utilization.
If i do this way, like I have 4 # TRX,I calculate TCH TSL’s, Occupied Erl from TCH# considering HR, & based on Utilization i do Degrow.
Now question here comes,Utilization will not include “Data”, So excluding Minimum or average used PDCH from Voice TSL’s will work ?
Or this will be a wrong calculation..
My System is E//
