Telecom Council Reports on Technology to Improve Transfer Rates of W-CDMA neasia.nikkeibp.com May 27, 2004 (TOKYO) -- The Ministry of Public Management, Home Affairs, Posts and Telecommunications (MPHPT) said its Telecommunications Council reported to it on policies to improve the sophistication of third-generation mobile telecommunication systems (3G). The council's report is to set forth the introduction of "high-speed downlink packet access (HSDPA)," for which NTT DoCoMo Inc plans to initiate a service based on the technology as early as the beginning of 2005. It also defines technological requirements for 3G in the 800MHz frequency band. The introduction of HSDPA will drastically accelerate data transmission of W-CDMA from the current maximum speed of 2Mbps to 14Mbps, enabling the drive-by speed to be between 2Mbps and 8Mbps. The current report of the council consists of three parts: (1) addition of technology for faster data transmission of W-CDMA called HSDPA, (2) use of 800MHz W-CDMA, and (3) settlement of technological conditions for CDMA 2000 in the 800MHz band. In part (1) of the report, the council recommends making a modulation method called 16 QAM available in addition to binary phase shift keying (BPSK) or quadri-phase shift keying (QPSK). According to the experimental results about throughput properties of HSDPA technology submitted by NTT DoCoMo to MPHPT, HSDPA has achieved a maximum of 14Mbps and an average from 3Mbps to 4Mbps in data transmission at a slow walking pace of 3km per hour indoors. Also in an outdoor drive-by test, data transmission was sustained at 2Mbps or faster through the experiment with a maximum speed of 8Mbps. The MPHPT is to revise the ministerial ordinance for Radio Law in the fall of 2004, following deliberations at the Radio Regulatory Council.
