Ericsson and NTT DoCoMo successfully complete WCDMA Interoperability Testing

April 7, 2005

Ericsson Mobile Platforms and NTT DoCoMo have successfully completed WCDMA Interoperability Testing (IOT). Testing has been conducted using Ericsson Mobile Platforms' global market leading WCDMA/GPRS platform U100. Tests have been performed in DoCoMo's laboratories followed by fully completed field tests in DoCoMo's live FOMA network.

Ericsson Mobile Platforms has previously announced that an estimated 30% of all globally sold WCDMA handsets in 2004 used the U100 platform.

"The successful completion of the IOT tests with DoCoMo was essential for global roaming using our platform," says Sandeep Chennakeshu, head of Ericsson Mobile Platforms. "The collaboration between Ericsson and DoCoMo started with the development of the WCDMA standard and we believe these successful tests will help to further secure global WCDMA deployments."

"Since the technology from Ericsson Mobile Platforms is widely deployed in leading WCDMA mobile phones, the completion of this testing is very important for DoCoMo as it would enhance our support for users roaming into DoCoMo's network in Japan," commented Mr. Takanori Utano, Managing Director of Research and Development Division, NTT DoCoMo.
