KDDI will start this service ahead of schedule and so filed registration with the Minister of Public Management, Home Affairs, Posts and Telecommunications today.

On April 1 this year, KDDI launched in major cities across Japan CDMA2000 1x, an IMT-2000 3G wireless system for the 800 MHz frequency that transmits data at speeds of up to 144 kbps.

Introduction policy for 2GHz frequency:
CDMA2000 1xEV-DO(1x Evolution-Data Only) is a high-speed wireless data system with transmission speeds of up to 2.4 Mbps. Development is taking place around the world and in November 2001, was registered as being IMT-2000-compliant at the International Telecommunications Union.
In Japan, the Radio Regulatory Council at the Information and Communications Council approved in April the technical standards and other issues for the system.

KDDI started field tests of CDMA2000 1xEV-DO in July 2000 to evaluate the system's performance. KDDI decided to move forward with CDMA2000 1xEV-DO for 2GHz frequency for IMT-2000 after the results of the tests demonstrated the system to be capable and technically mature and able to respond to the changing environment for Internet connectivity such as the spread of high-speed Internet connections such as ADSL.

Start time (expected)
April 2003	Begin Trial Service in the Kanto region around Tokyo
October 2003	Begin full service in Kanto
March 2004	Expand the service area to Chubu and Kansai region around Osaka and Kyoto

CDMA2000 1xEV-DO is a high-speed best-effort dedicated data system that is different in system design from cdmaOne and CDMA2000 1x. From the trial service, KDDI will optimize systems and terminals for use on a corporate-wide scale and for various user environments to create a full-scale system that answers user's needs.
The results of the trials, and the content of the full-scale service will studied in detail at a later date.
