Dell is making sure it has its wireless bases covered. The latest: the computer company inked a deal to integrate Cingular Wireless' UMTS/HSDPA capabilities into its laptops next year. Earlier this week, Dell made a similar commitment to Verizon Wireless' 1X EV-DO technology.

Dell will debut its first laptop with integrated high-speed downlink packet access (HSDPA) in the first quarter of 2006.

The deal between the two companies is not the first time Cingular and Dell have teamed up to promote wireless connectivity. Dell currently sells Cingular's GC83 EDGE PC card modem to its notebook customers.

Cingular expects to have its UMTS/HSDPA network up and running in 15 to 20 markets by the end of this year. By the close of 2006, however, the company expects its coverage to span most major U.S. markets.

Cingular is not the only carrier forging high-speed wireless deals with laptop makers. Earlier this week, Verizon Wireless announced several deals of its own. Lenovo will debut two ThinkPad Z models with integrated support for Verizon's EV-DO technology, while HP and Dell first plan to sell Verizon's PC Cards to their customers and then integrate the technology at a later date.

Not to be left out of the loop, Panasonic announced today that its Toughbook Rugged and Semi-Rugged PC are in the broadband wireless space as well. The computer company said it began shipping select notebooks with integrated support for Verizon's BroadbandAccess service.

The Toughbook series also has been certified to support Cingular's EDGE network, according to Panasonic.
