Problem 1 – “Service upgrade”

There is a need to model the impact of upgrading the service bandwidth, the service take rate and the service mix on the accessnetwork.

For a given market, the access network planners want to perform Bandwidth Upgrade Scenarios, Uptake Growth Scenarios, and Service Mix Scenarios

The access network planners have to dimension the required capacity of the access nodes, to optimize the access network and to calculate related costs to upgrade it.

Problem 1 – extension of the study

There is a need also to assess the cost for services in order to price products. Such study facilitatescomparison of multiple service costing scenarios for strategic decisions on product pricing.

Additional parameters are:• price per service/bundle of services• growth in customers from each service class• growth in customers from each speed package

The planner have to dimension the access network, to calculate all related costs and based on the expected revenue to providing insight into the Return-on-Investment and the profitability.


Problem 2 – Techno-economical Access Study

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
