I fully agree with you, it is possible to compute a capacity out of a predicted offered traffic… It works at a cell level for instance.
I’m just pointing out that any serious dimensionning engineer will never based a study on the traffic offered only (talking about radio capacity). It is possible, but it is useless.
If you’re dimensionning a BSC, or A interface, or a MS, etc.. ok, a capacity-based study will work.
I’m sorry if i’m being stubborn, but the guy is gonna build a tool that is absurd… it’s a pity ! he’d rather spend his time doing something that’ll help us roll-out a network 😉
