The wireless technology known as WiFi, which allows users of personal and hand-held computers to connect to the Internet at high speed without cables, got a significant stamp of approval on Thursday when AT&T, IBM and Intel announced a new company to create a nationwide network.
The unruly technology, which has largely been a playground for hackers, hobbyists and high-technology start-ups, is already sprouting mushroom-like in coffee shops, bookstores, airports, hotels, homes, businesses and even a few parks.
The new company, Cometa Networks, has set ambitious goals for itself: to deploy more than 20,000 wireless access points by the end of 2004, placing a cable-less high-speed Internet connection within a five-minute walk in urban areas or a five-minute drive in suburban communities.
Executives from the technology companies and the two investment firms, Apax Partners and 3i, that joined to create the network said they would begin offering their service through cellular and wired telephone companies, DSL and cable Internet service providers and other Internet retailers sometime in 2003.
The service is intended to let subscribers pop open their laptops and have a seamless high-speed wireless extension of their personal or corporate Internet services -- initially in the 50 largest metropolitan areas -- without having to give credit card numbers or enter additional information, as is generally the case now. Connections would generally be at least the speed of a typical home broadband connection.
The Cometa executives said that they expected the national availability of the wireless network would combine with Intel's planned inclusion of wireless Internet capability in all of its mobile microprocessors next year to spur a fundamental shift in the way Americans will use the Internet.
"This is that big," said Dr. Lawrence B. Brilliant, chief executive of Cometa Networks. "It's that exciting; it's that much of a distortion in the computing field. It's a change in the way people use technology."
Until now WiFi has been viewed by many technology analysts as an upstart, from-the-bottom technology that has the potential of upsetting other capital-intensive technology deployments, like the expensive next-generation, data-oriented cellular networks known as 2.5G and 3G that are being established by companies like AT&T Wireless, Cingular, Nextel, T-Mobile, Sprint and Verizon.
But Cometa executives said that because they had chosen a wholesale business strategy, in which they will not sell Internet service directly to consumers or businesses, it was more likely that the two technologies would complement each other. In addition, users of the wireless access points would generally be stationary while connecting to the Internet.
Industry analysts have said they believe that growing WiFi use could steal valuable subscribers from cellular companies that are hoping consumers will begin using their cell phones for data services like movie times, restaurant reviews and shopping deals wherever they are traveling.
The Cometa executives said they were not certain how the new network would be used, but were convinced that the nation's 100 million Internet users would begin to use their portable computers in new ways once connections are widely and easily available as they travel.
