АСТЕЛ 2010 СОФИЯ, април 2010 г. Панел II_IS - 5 Problem 1 – Service bandwidth upgrade 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 planners have to dimension the required capacity of the access nodes, to optimize the access network and to calculate related costs to upgrade it.
