Next generation access costing ‘without a map’

An efficient and credible methodology for evaluating the cost of upgrading a copper-based local-access infrastructure to provide high-speed broadband (or so-called next generation) access (NGA)

Our example model includes scenarios that compare the headline revenues and capex of deploying VDSL connectivity with feeder fibre or a complete GPON solution for FTTH against a baseline greenfield or current ADSL implementation.

We characterise a generic city with a division of households between four separate density classes (households per sq km). A representative street pattern is used to derive general rules to link coverage of households with distance covered for buildings passed and households connected, with awareness of how multiple dwellings and tower blocks distort the relationship between buildings passed and potential households connected.
