Hi ,
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

Hi 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.
