Sony Ericsson expands US HSDPA products

Sony Ericsson is expected to roll out as many as six mobile phones with high speed downlink packet access (HSDPA) technology in the US market by the end of the year.

The release will also include the company's most advanced camera phone with 8.1-megapixel resolution.

All operate in frequency bands making them suitable for sale in the US.

Most of the devices are triband 850/1,900/2,100MHz HSDPA models, with 2,100MHz operation intended for roaming in European networks.

The devices are also quadband GSM/EDGE phones.

One previously announced model, the Xperia X1, adds high-speed uplink packet access (HSUPA) technology. In HDSPA and HSUPA modes the X1 operates in four US bands: 850/1,700/1,900/2,100MHz.

The 8.1-megapixel camera phone, the Cyber-shot C905, is the company's first slider under the Cyber-shot sub-brand and the company's highest-resolution camera phone.

The company expects to make it available in the US in the fourth quarter as part of a worldwide launch.
