GuestHi ,
I am an young radio engineer (GSM network in Croatia).
I see we have the same problem , and , still, I see only the questions not the answer on GSM and UMTS usage of ERLANG B , ERLANG C and MULTIERLANG – upon Campbell`s theorem.
I need to do some calculations for GSM and UMTS traffic (calculation of number of voice trunks per user, …), so I would very appreciate if you could share some of your knowledge on this subject.I would appreciate if you would send me an email with the answer, if you have one ;-))).
Thanks and best regards,
Heror

GuestHi Kumar,
The formula for any type of Erlang calculation is;
A= BHCA * MHT / 3600
A= Traffic
BHCA= Busy Hour Call Attempts
MHT= Mean Holding Time.
