DoCoMo's forced to delay commercial 3G launch

date: May 26, 2001

The Ministry of Posts and Telecommunications of Japan forced NTT DoCoMo to delay the full-scale launch of its 3G cellular phone service because of government concern over data transmission quality to the consumers.

The government postponed DoCoMo's license approval for of the high-speed data transmission service of up to 386kps and may be delayed until next year or later from the planned October launch.

The telecom ministry decided the system for the data internet service is unstable and the quality cannot be guaranteed, but will approve the voice service.

DoCoMo has so far failed to fix glitches in the software that allows data packets to pass on from one cell to another.

The telecom ministry will allow the company to carry out the introductory service in early June, including high-speed data transmission. But the ministry will require NTT DoCoMo to explain to users that it cannot guarantee the quality of data transmission. NTT DoCoMo will also be required to devise measures to deal with problems with the service.

The ministry is expected to require the company to report regularly on the performance of the data service until NTT DoCoMo launches the 3G i-mode service commercially.
