The NTT DoCoMo Inc has developed a technology that increases the speed of its 3G (third-generation) cellular telephone FOMA service by more than 30 times, putting it on par with ADSL (asymmetric digital subscriber line) service.
The technology would enable its handsets to receive television and high-quality music content, which cannot be handled by its current FOMA service.
The telecom firm hopes to have the technology deployed as early as 2005.
The new technology employs a more efficient form of transmission by allotting to specific users frequencies for intensive use. This allows transmission speeds to reach a maximum of 14Mbps, far faster than the current 384kbps. DoCoMo hopes to develop prototype equipment this year.
NTT DoCoMo also announced that it will establish DoCoMo Communications Laboratories Beijing Co. to research and promote the advancement of mobile communication technologies for fourth-generation (4G) and beyond. Capitalized at 5.3 million US dollar (approx. 630 million yen), the new wholly owned subsidiary of NTT DoCoMo will be set up within this year.
China has aggressively committed to 4G research and development, and is expected to evolve the requisite new standards. DoCoMo expects the envisioned laboratory to promote advanced mobile communications technology in both countries in line with the joint statement issued at the People's Republic of China-Japan-Republic of Korea Information and Telecommunication Ministerial Meeting held last September in Marrakech.
