Wi-Fi: A Wild Card in Telecom’s Restructuring - Knowledge@Wharton
...A wild card as the industry restructures is a technology called “wi-fi,” which is short for wireless fidelity. Wi-fi allows wireless connection to the Internet; the data moves over the airwaves, via radio frequencies, to antennas installed in computers. The signals are low power so users generally have to be within a few hundred feet of a transmitter. An area reached by a transmitter, or series of transmitters, is known as a “hot spot.” Some airports and hotels are already equipped for wi-fi usage.... “At IBM, we believe wi-fi is a disruptive technology, with tremendous opportunities and risks for wireless carriers,” said Dan Papes, vice president for IBM Corp.’s North American wireless division. “We did about $2 billion in wireless services last year and a quarter to half of that was related to wi-fi. Intel already has embraced the technology. By the end of this year, every laptop PC will have wi-fi capability.”
