Intel Corp said on Wednesday it had won a mobile WiMax chip order from the world's top cellphone maker Nokia, which will use its semiconductors in Internet-focused devices from 2008.Nokia will roll out the first WiMax-enabled Internet tablets using Intel chips in the first half of 2008, a Nokia spokeswoman told Reuters.

Mobile WiMax, the high-speed wireless standard, is expected to support Internet access at speeds as much as five times faster than typical wireless networks, though it will be slower than the fastest wired services.

Intel has had little success in the mobile phone chip market and ended up selling its cellular chip unit to Marvell last year. Its push behind short-range wireless technology Wi-Fi was a big factor in the widespread adoption of that technology.Texas Instrument is Nokia's largest chip supplier, and it also uses STMicroelectronics, Broadcom and Infineon as suppliers.

Currently, Nokia is not manufacturing mobile devices using Intel chips.Intel said the companies were testing interoperability across Intel's forthcoming WiMax silicon "Baxter Peak" for laptops and mobile Internet devices, Nokia WiMax devices and Nokia Siemens Networks' WiMax infrastructure equipment.

Intel, Nokia and NSN have already started testing devices with other device makers' products, using Sprint Nextel's laboratory in Herndon, Virginia, Intel said.

The world's top cellphone maker, Nokia, has unveiled a new phone model, the Nokia E51, for corporate users and said it still expects to fast growth in the mobile e-mail market.

Nokia said the classic "candy bar" shaped phone model will be globally available later this year, and retail for 350 euros ($485), excluding subsidies and taxes.

Nokia's enterprise unit turned to profit in the last quarter after years of losses, helped by the success of its E65 phone model.

The unit has been hoping to benefit from runaway success of RIM's Blackberry models, but it said still only 2 percent of corporate e-mail accounts are mobile, similar to the situation a couple of years ago.

"We believe it will change quickly," Antti Vasara, head of device business at Nokia's enterprise unit told a news conference.

Vasara said by 2009 there should be 880 million mobile workers using either cellphones or laptops.

"Less and less people are bound to their desks while doing their work," he said.
