5. Problem 1 – Service bandwidthupgrade There is a need to model the impact of upgrading the service bandwidth bandwidth, the service take rate and the service mix on the access network. For a given market, the access network planners want to perform Bandwidth Upgrade Scenarios, Uptake Growth Scenarios, and Service Mix Scenarios The access network plannershave to dimension the required capacity of the access nodes, to optimize the access network and to calculate related coststo upgradeit.

19. Problem2 – Selection of Access Technology Aim is to investigate the techno-economical impact of various access technologies on the network for a given market Multiple techno-economical studies are carrier out for the purpose to determine the optimum access technology for the network Selection is done by comparison of the economical parameters for each access technology
