The technology for delivering fast Web access over large areas could help upstart communications outfits nab share from established players Wi-Fi has changed the way people navigate the Internet, and in record time.
The technology, which is used to create wireless networks in small areas such as homes, offices, and parks, allows millions to move about freely while they surf the Web with laptops and PDAs. Demand is soaring, thanks to faster, cheaper, and more reliable technology, and to open standards that let tech giants like Intel (INTC ) bundle Wi-Fi radios into mass-market computers. The number of Wi-Fi users is expected to soar 57% this year, to 118 million worldwide, according to Pyramid Research. Not bad for a technology that's only a few years old.
Encouraged by Wi-Fi's success, tech companies are poised to launch a new wireless technology called WiMax, which will allow even faster Internet access across larger areas. WiMax creates "hotspots" that stretch dozens of miles and allow users to surf the Web wirelessly at speeds that are much faster than connections via a digital subscriber line (DSL) or cable modem. A single WiMax radio is 20 or 30 times faster than a household broadband connection. |
