We have a request to check whether a calculation regarding the future rollout that the Business department does is correct.
The theory is simple: they take a reference year ie 2015 and we had in the netwrlork X number of cells with Y number of DL data traffic. Based on this ratio Y/X the business and design departments calculate the rollout needed for future years (if Y increases 20% then X increases likewise).
We are trying to refine this methodology . Do you have any suggestions?
