First WiMax laptop card approved by FCC, Clearwire says

U.S. regulators have approved the first WiMax wireless broadband laptop PC card to be offered by Clearwire Corp., and it should be available to users later this year, the company said.

The Federal Communications Commission approved a WiMax laptop PC card that fits into a standard Type II laptop card slot and can be used with the Windows Vista and XP operating systems, Clearwire said in a statement yesterday. The card works on Clearwire's WiMax network, which has been built with Motorola Inc. wi4 Expedience wireless networking equipment.

Approval of the high performance WiMax card should propel the use of WiMax by broadening the potential base of customers, Clearwire said.

Laptop PC users were instrumental in increasing the popularity of Wi-Fi, which supporter hope WiMax would replace with its speedier wireless Internet service and wider ranging access. Wi-Fi became popular because it freed people from sitting at home connected to the Internet by wire, and instead allowed them to sip coffee at Starbucks while reading e-mails wirelessly on their laptop PCs.

Clearwire, of Kirkland, Wash., expects the WiMax laptop PC cards to be available in the second half of this year. The company currently offers broadband wireless services in the U.S. and Europe. Its subscribers rose to 206,000 as of the end of last year, from just 1,000 on Sep. 30, 2004, it said when it filed to list on the Nasdaq Stock Market LLC in February. Its subscriber base has grown despite wireline alternatives for users, including broadband cable modems and DSL (digital subscriber line) Internet service.

At the end of last year, Clearwire services were available to 9.6 million people, including 8.6 million throughout the U.S., and 1 million in Brussels, Belgium, and Dublin, Ireland, the company said.

WiMax base stations can send broadband Internet signals to far greater distances than Wi-Fi technology. Although estimates vary on how far WiMax signals can go, in densely populated cities, where users are not likely to be positioned within sight of access points, the distance should be between 2 km and 4 km (1.2 to 2.4 miles).
