Broadband communications: the commercial impact

The impact of broadband ISDN (integrated services digital network) is assessed. It is pointed out that the key step in its introduction, i.e. the replacement of the copper wire infrastructure by optical fiber, is already taking place. Two alternative routes for the introduction of broadband services are described: the market-driven route and the investment-led route. The market-driven route entails carriers responding to the demands currently being made of them. In the investment-led route, carriers lead the market and create demands by substantial investment in fiber residential networks. Carrier costs and rewards and anticipated market growth are examined. Broadband applications, the role of video communications, and the technology that will be used are briefly examined.<
