InfoWorld - It's easy to be wowed by Japan's mobile communications infrastructure. "Next-generation" 3G coverage is now so ubiquitous that carriers have already stopped launching 2G phones; an impressive array of attractive handsets offer free digital TV; phones can be used to pay for goods and train rides, thanks to embedded contactless smart cards; and on the mobile information superhighway data whizzes along at 3.6Mbps.

(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.
