Hello

Cell utilization -Traffic (erl)*100/Traffic design (ERL table (B))

Eg

CELl utilization Per CELL

Cell _1 with real traffic =10 erl
and TCH=12 channel and GOS =2%

so we have to review erlang table B , we will find the design traffic at TCH = 12 and GOS =2% =6.615

Design traffic =6.615 so cell utilization = 10*100/6.615

i hope it is clear
