The next generation of Nokia’s Internet Tablet will feature the long-range wireless broadband technology known as WiMAX, the latest push by the Finnish cell phone maker to develop an all-in-one handset.

The company, which controls about one-third of the worldwide mobile phone market, said it had already signed a deal with U.S. carrier Sprint to make the new tablets available to subscribers in the first half of 2008.

“We are preparing for the day when people are carrying computers in their pockets and not phones,” said Nokia vice president Ari Virtanen.

Nokia did not rule out the possibility of also incorporating a cellular radio to the series at some stage in the future but said it would not be with the next product release. That would be a commercial decision not a technical one, said Mr. Virtanen.

Nokia’s tablets are pocket computers that feature short-range WiFi technology and high resolution screens that allow users to surf the web, make Internet Protocol phone calls, and send and receive email and text messages.

Helping to bridge the divide have been Nokia’s most recent mobile phones, such as the N95 and E90, which also sport WiFi and Bluetooth technologies. This means that users can browse the Internet or make phone calls by-passing their cellular carriers’ networks.

Internet tablet sales are steadily increasing although they are still not at mobile phone sales levels, said Mr. Virtanen.

Convergence between mobile phones and computers will continue and Nokia will lead the trend by approaching it both from the mobile phone and computer ends, he said.

“Today’s phones with computer capabilities are still phones at the heart,” he said. “We are making devices with computers at the heart and phone functionality on top.”

Nokia last week announced a corporate strategy shift that moves the company away from being a mobile phone maker and closer to that of an internet services company. This has in fact been a long-held ambition of the company but one which it now acknowledges publicly.

Computer maker Apple’s entry into the phone market may have hastened Nokia’s decision to go public, as may have reports of similar plans by other computer related companies such as Google and Microsoft.
