20Access Bottleneck Issue Development of broadband access systems standards and technologiesDemand for bandwidth and a scalable network infrastructure.FTTH infrastructure as an alternative to less-scalable xDSL, cable modem and fixed wireless access deployments.Governments - From the bandwidth-limited information society of today and the bandwidth-rich information society of tomorrow.Governments - FTTH deployments
22Access Network IssueDevelopment of broadband access systems standards and technologiesService providers - Detailed plan for migrating the different subscriber segments from circuit-switched to pure packet-switched access infrastructures.Service providers - Ethernet carriers that start to claim a stake in the telecommunications services market.
23Access Network IssueDevelopment of broadband access systems standards and technologiesFiber technologies - Edge of access networks. Home and desktop.Incumbents - Business models segment by segment.Internet Protocol-based and asynchronous transfer mode-based access solutions.Competitive operators - Conservative when forecasting payback periods for new technologies and select their target customers carefully.
