(InfoWorld) - NTT DoCoMo's 3G network in part of central Tokyo was hit by trouble on Saturday resulting in problems for tens of thousands of users. Problems with a switching board at a DoCoMo facility in the capital's Shibuya district caused the disruption, the carried said. Users in Shibuya and the nearby districts of Shinjuku, Okubo and Minami-Aoyama found calls and packet communications problems from 4:34am to 9:29pm local time on Saturday. NTT DoCoMo estimates around 92,600 subscribers were directly hit by the problem. The areas involved are some of the busiest parts of Tokyo and popular with thousands of shoppers at the weekend. NTT DoCoMo launched its WCDMA (Wideband Code Division Multiple Access) in 2001 becoming the first carrier in the world to offer commercial service based on the standard, which is now in use in many nations around the world.

(InfoWorld) - Vodafone and High Tech Computer Corp. (HTC) have signed an agreement to jointly develop and market 3G (third generation) smart phones in Japan, the companies said Thursday. The deal makes Vodafone the second major mobile operator to work with HTC, the world's the largest maker of handsets that use MicrosoftÂ software. In July, HTCÂ inked a deal with NTT DoCoMoÂ to sell Windows Mobile-based smart phones. HTC is a key partner for Microsoft in its battle to win more market share with its mobile phone OS, and Japan is an important market for several reasons, mainly because of the early adoption of 3G services in the country.

(InfoWorld) - NTT DoCoMo came close to hitting another data transmission milestone in its research into next-generation cellular telephone systems during an experiment conducted in Japan on Dec. 25 last year. The company, Japan's leading cellular carrier, managed to transmit data at close to 5GbpsÂ to a receiver moving at 10 kilometers per hour, said Yoshiki Kakuda, a spokesman for the Tokyo company. He said the company's public relations department didn't know the exact speed achieved but that it was close to the 5Gbps mark. About a year earlier NTT DoCoMo succeeded inÂ transmitting data at 2.5GbpsÂ and this time managed to double that by increasing the number of MIMO (multiple in multiple out) transmitting and receiving antennas from six to 12 each and using better signal processing in the receiver. MIMO involves sending data using multiple antennas to increase the total throughput. The result was a doubling in the amount of data transmitted in the same 100MHz chunk of radio spectrum. Details of the experiment will be detailed at next week's 3GSM World Congress in Barcelona, Spain. NTT DoCoMo has been working on what it calls 4G (fourth-generation) technology for close to 10 years but the technology remains some way from commercialization. The carrier had previously said it plans to launch 4G in Japan around 2010 but recently indicated it plans to wring more speed out of its WCDMA (Wideband Code Division Multiple Access) 3G network before switching to a new technology. The carrier plans to launch a "Super 3G (third-generation)" service around 2010 that will offer data transmission at around 100Mbps. When NTT DoCoMo launched its 3G network in 2001, it could carry data at 384Kbps but that was recently raised to 3.6Mbps with the launch of an upgrade called HSDPA (high-speed downlink packet access). Carriers in other countries are also deploying the faster technology on their networks.
