Resumo(s)
Broadband technologies have view great growth
over the past decade. But, the main part of this development
and growth has been in the core networks, and the capacity
of the access network to delivery broadband services
remains as a challenge ("last mile problem"). The access
network remains a bottleneck in terms of the bandwidth and
service quality it affords the end user. By other side, the
access network is much more spread geographically and
covers larger areas. Then, this part of the network is usually
the most expensive component in terms of capital investment
and OAM cost. Some studies reefer that this networks
required 70% of the total investment. Several access
technologies can be used in this part of the network, which
can be used to resolve the bandwidth bottleneck and the
investment problem: xDSL, HFC, FTTx, FWA, WiMAX,
PLC, Satellite, etc.
This paper presents a methodology and a tool that compare
and evaluate broadband access technologies. The paper
presents a techno-economic analysis of eight broadband
technologies for access networks: digital subscriber line
(DSL), hybrid fiber coax (HFC), power line
communications (PLC), fiber to the home (FTTH), fiber to
the curb (FTTC), fiber to the cabinet (FTTCab), and
wireless alternatives such as WiMAX and satellite. Several
actors (such operators, service providers, …) could use this
tool to compare different technological solutions, forecast
deployment costs, compare different scenarios, etc.
