Hacked 802.11b dodges the coming bandwidth congestion on 2.4GHz?

“CUPERTINO, Calif., June 7 — Anyone looking for the next big thing in Silicon Valley should stop here at Layne Holt’s garage.

Mr. Holt and his business partner, John Furrier, both software engineers, have started a company with a shoestring budget and an ambitious target: the cable and phone companies that currently hold a near-monopoly on high-speed access for the “last mile” between the Internet and the home.

At the core of their plan is the inexpensive wireless data standard known as Wi-Fi or 802.11b, which is already shaking up the communications industry, threatening to undermine the business plans of cellular phone companies by offering a much cheaper method for mobile access to the Internet.

The pair’s company, known as Etherlinx, has taken the 802.11b standard and used it to build a system that can transmit Internet data up to 20 miles at high speeds — enough to blanket entire urban regions and make cable or D.S.L. connections obsolete.” [more…]
