Wireline systems are used to provide the broadband access links between infrastructure gateways and home and business premises as well as the local area networks within those premises. Broadband cable and digital subscriber line (DSL) access links capitalize on the installed wired infrastructure for television and telephony, respectively, They are the predominant access technologies today, and there are no apparent replacements on the horizon. In contrast, ethernet, the predominant wireline broadband LAN technology for business, requires a dedicated wiring infrastructure. The wiring installation cost in older structures is significant, and it threatens to undermine ethernet's predominance as more and more homes are retrofitted with LANs. Competing wireline systems, HPNA and HomePlug, employing the telephone and electrical power wiring networks, respectively do not pose as great a threat as do wireless broadband systems.
This talk will provide an overview of each of the wireline technologies. This will include their system architecture, present and future circuit implementations and the author's biased forecast of their success in the marketplace.
