Abstract: This deliverable presents techno-economic results for fixed access networks. It summarises two major use cases, the Network Migration and the Native Ethernet (Greenfield) approach.

It has been observed that the migration from a best effort access network to a multi-service architecture based on Ethernet or IP forwarding is favourable in comparison with an ATM-based evolution scenario.

The introduction of new network functions like DHCP based IP configuration, QoS (50% Best effort guaranteed) and multicast leads to cost savings in aggregation network of about 25%.

Even by upgrading the framework assumptions the first mile related case studies confirm former results for an incumbent network operator: complete Fibre to the Cabinet (FTTCab) deployment scenarios are profitable in dense urban and urban areas only and the Fibre to the Home (FTTH) is only profitable in combination with an optimized roll-out approach (sensitivity analysis result).
