The erlang B chart is used to find the Traffic intensity in a system with specified no. of channels that has to meet given probability of blocking. Cellular network providers use it to determine the maximum traffic intensity their system can support. It is also used to find the no. of channels required when establishing a system that should meet specified traffic and grade of service
erlang chart is just like any other chart and using it you can find the average traffic intensity of a system given its number of channels and its GOS...

the blocking probability is given in the y axis and it is the GOS... now search for the line C=1 and find what value of A it gives when GOS=0.005 that is all... this is the value of A you have to find...
now divide A by Au to find the number of users....
Actually in the Rappaport the graph for A<0.1 is missing. For your given data you need to follow the curve c=1 and find where it crosses the horizontal dotted lines for the given GOS.The curve c=1 is not fully given there..

No. I think its 10.5
You need to follow c=20 and stop where it crosses the gos=0.02 and then stop at that point and see the vertical dotted line at that point and determine the traffic intensity
