Epsonís World-Leading GPS Technology to be Incorporated in NTT DoCoMoís 905i Series Mobile Phones


Seiko Epson Corporation (ďEpsonĒ) today announced that all eight of the GPS-capable models in the 905i series mobile phones being released by NTT DoCoMo, Inc. will be incorporating the world-leading*1 A-GPS (Assisted Global Positioning System) reception technology*2 that Epson provides to mobile phone manufacturers for mobile phones and portable information terminals.

All GPS-capable mobile phones in the 90X series from the December 2006 release of the 903i series onward are equipped with Epsonís S4E19863*3 GPS module, of which a total of 12 million units have already been shipped.

The 905i series models scheduled for release at this time incorporate not only these GPS module but also integrated LSI that employ Epsonís advanced original GPS technology, and contribute to NTT DoCoMoís ability to provide a broad range of advanced contents services using GPS.

Epsonís advanced original technology and know-how related to GPS baseband processors and A-GPS software have achieved a remarkably broad detection range capable of identifying signals ranging from strong outdoor signals to weak indoor signals, making possible a level of sensitivity that is several dozen times greater than that found in conventional GPS technology. Furthermore, as the module supports the three 3GPP-compliant positioning modes (MS-Based, MS-Assisted, and Autonomous), it is capable of delivering the worldís most advanced GPS positioning performance in any application and under any network environment. These technologies make it possible to obtain high-speed and high-precision positional information from locations that are indoors, outdoors, or within moving vehicles. Mobile phone users are thus provided with access to emergency support services and location-based services, and thereby have their needs and safety requirements fully met.

Epson will continue to proactively pursue new developments in the field of positional information technologies in order to provide its advanced original technologies to a wide variety of industries, including the mobile phone industry, as well as contribute to the further growth of the location-based services market.
