It will also exert an enormous effect on the electric utility industry as a way to cut costs, improve service, and generate new revenues.

Many utilities have recognized the magnitude of the potential opportunity. Some, like Pacific Gas & Electric (with partners TCI and Microsoft) and Public Service Electric & Gas (with partners led by AT&T), are announcing high-profile broadband-oriented pilot projects. Others, like Kansas City Power & Light and Union Electric (with partner CellNet), are quietly rolling out utility technology to most, or all, of their customers. Virtually every major utility is at least studying the subject.

A Network of Networks

The Superhighway consists of many communications technologies (em fiber-optic and coaxial cable, numerous forms of wireless, twisted copper pairs, and especially software: operating systems, network management software, applications, user interfaces, and messaging protocols. The software is the glue that holds together the digital information being transmitted over the networks.

The Infobahn is a network of networks that comprises all of these technologies. Let's say a utility marketing representative (em a "road warrior" (em sends a fax from her mobile laptop computer over a cellular phone. The signal is received at a cell site, which forwards it using a microwave radio link to a master control station. This station puts the fax on a
