Hi Waleed and every Body
About Calculating the capacity that the BTS can carry depends on the distribution of TRXs among cells of that BTS, for example if the BTS has a configuration of 3+3+4 the capacity will deffer from that of a configuration of 2+2+6 or 5+5 the reason is the way that the Erlang table calculates the capacity.
