| 14th Febuary 2006 - NTT DoCoMo, Inc., Renesas Technology
Corp., Fujitsu Limited, Mitsubishi Electric Corporation and
Sharp Corporation today announced that they will jointly develop
a comprehensive mobile phone platform*1 combining a single-chip
LSI for dual mode handsets supporting HSDPA*2 /W-CDMA and GSM/GPRS/EDGE,
and core software such as operating systems. The new mobile
phone platform will help accelerate the global adoption of W-CDMA
services including FOMA™, and lower the costs of these
handsets. The companies expect to have the platform developed
around Q2/FY2007 (July-September).
The next-generation mobile phone platform is built on the
previously developed single-chip LSI technology of NTT DoCoMo
and Renesas since July 2004, which combines a baseband processor*3
and the SH-Mobile application processor*4 for dual-mode W-CDMA
and GSM/GPRS phones. The jointly developed platform adds new
functionality, such as support for HSPDA and EDGE technologies
and full development support including OS, middleware and
drivers.
The platform can be implemented directly as a base system
for W-CDMA handsets and eliminates the need for mobile phone
manufacturers such as Fujitsu, Mitsubishi Electric and Sharp
to develop a separate system for the common handset functions
significantly reducing the time and cost of development. At
the same time, it allows them to invest more time and resources
into developing handsets that are distinctive to them.
The platform will be initially available for FOMA, and later
for UMTS*5 offered by Renesas. When the platform is widely
spread and adopted, a further cost reduction of the handsets
will be expected.
Notes
- Mobile phone platform: A base system needed for mobile
phones, which integrates software and hardware such as a
baseband processor.
- HSDPA: High Speed Downlink Packet Access. It is based
on the enhanced and high-speed version of the 3G W-CDMA
data transmission, also known as the 3.5G data transmission
standard. The data transmission speed with FOMA tops at
384kbps, and under the standard 3G specifications it reaches
up to 2Mbps today. However, with the introduction of HSPDA,
theoretically, the maximum data transmission speed can increase
up to 14Mbps. Also, this platform will support the transmission
speed up to 3.6Mbps.
- Baseband processor: A processor that handles the communication
function within the mobile phone.
Application processor: An LSI that processes multimedia
applications such as emails with still pictures and movies,
audio and video playback, video telephony capabilities and
more.
- UMTS: Universal Mobile Telecommunication System. A European
standard for 3G-telecommunication system compliant with
IMT-2000 with the highest baud rate of 2Mbps. In this context,
we refer UMTS as a synonym for W-CDMA.
