PNO and cable operator broadband upgrades

This chapter presents a techno-economic analysis of broadband access network upgrade strategies for public network operators and cable operators in a competitive environment in the residential and small business market. The study focuses on network evolutionary paths from the existing network towards a target broadband architecture. The intermediate steps and final network solutions include the technology options of broadband twisted pair modems, hybrid fibre coax networks and asynchronous transfer mode (ATM) based passive optical networks (PONs) [1].
