artimi.bmpArtimi, a company making ultra-wideband technology, which lets you speed up the transfer of video or other files by more than 100 times, has raised more money to help it deliver on that promise.

The Santa Clara, Calif. company has raised $5 million from Khosla Ventures, to be announced tomorrow (Wednesday), and plans to ship its product this year.

At first, Artimi chips will be available via a plug-in device for wireless USB. You plug in a device to your phone or camera, and you can transfer videos or other data to your PC at rates at least as a hundred times fast as you can with the fastest cellular networks, such as EVDO. It will also save you power. By next year, Artimi hopes to have its chip embedded in digital cameras and camcorders, and by 2009, in phones, so that you don’t need any hardware. Among Artimi’s competitors are Alereon and Wisair.

With camera phones getting more sophisticated, people are taking pictures with higher resolution, and eventually they’ll be taking multi-gigabyte-sized movies. But at that size, they’re getting near impossible to transfer from phones, said Dave Weiden, partner at Khosla Venture. Some cameras are running out of batteries during transfer.

Artimi supports both Wireless USB and next-generation Bluetooth.

The funding brings Artimi’s total backing to $50 million. Artimi’s other investors include Accel Partners, Amadeus Capital Partners, Index Ventures, Oak Investment Partners, and Bank of Scotland Growth Equity.
