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 has embarked on a month-long experiment of a Super 3G (third-generation) cellular system. The indoor experiment will test data transmission speed and NTT DoCoMo hopes to hit a downlink speed of 300Mbps, it said Friday. First trails will involve the use of a single antenna on both the transmitter and receiver and then the use of up to four multiple-input multiple-output (MIMO) antennas. The tests will also look at the speed with which communications can be handed from one base station to another. Super 3G, which is also known by the acronym LTE (long-term evolution), uses the same radio spectrum band as current 3G services, but that's one of the few similarities. Super 3G allows for a number of different bandwidth channels and uses different modulation systems to transmit the data. It is envisaged to eventually allow data links at 80Mbps to the network and 300Mbps from the network. The company, which is Japan's largest cellular carrier, has been working on Super 3G for some time and anticipates introducing the technology in Japan sometime around 2009 as a stepping stone between current so-called 3.5G technology and future 4G (fourth-generation) systems. NTT DoCoMo has also been aggressively pursuing 4G system development. In experiments conducted in late December last year the carrier came close to hitting aÂ 5Gbps data transmission speedÂ from an experimental 4G system to a receiver moving at 10 kilometers per hour.

(InfoWorld) - The Chinese government will not issue licenses for 3G (third-generation) mobile services until the first quarter of 2008, according to a Chinese report. China's Ministry of Information Industry (MII) will not issue the licenses until a new round of tests involving theÂ homegrown TD-SCDMAÂ (time division synchronous code division multiple access) 3G technology ends next year, reported Caijing magazine in its latest issue. Delaying the releaseÂ of the 3G licenses will give TD-SCDMA and its backers additional time to close the gap with more mature 3G technologies, WCDMA (wideband CDMA) and CDMA2000 EV-DO (evolution data optimized). In December, China's Minister of Information Industry, Wang Xudong, reiterated a promise that commercial 3G services would be available when Beijing hosts the Olympic Games in 2008. Issuing licenses during the first quarter of 2008 would still allow operators to meet this goal, even if they have little time to expand their 3G coverage areas throughout the country. The eventual release of 3G licenses will coincide with a restructuring of China's major telecommunications operators, which are currently split into fixed-line and mobile carriers, Caijing reported. The four major Chinese telecommunication operators, which are all state-owned, are currently divided into fixed-line and mobile carriers. China TelecommunicationsÂ (China Telecom) and China Network Telecommunications Group (China Netcom) are the country's primary fixed-line carriers, offering voice and Internet services. To avoid overlap and direct competition between the two carriers, the country was divided up between the two companies. China Telecom serves western and southern China, including Shanghai, while China Netcom's market covers the north, including Beijing. The two mobile carriers, China Mobile Communications (China Mobile) and China United Telecommunications Co. (China Unicom), are not restricted geographically but they use different technologies. China Mobile operates a GSM (Global System for Mobile Communications) network and has the most subscribers, while China Unicom has both a GSM network and a CDMA service that is its primary network and offers faster data downloads. Determining how these companies will be structured, and what mobile networks they will have, is not something that will be determined by MII alone. The decision also involves the State-owned Assets Supervision and Administration Commission (SASAC), which oversees China's state-owned companies and is a central player in the 3G licensing process. Further complicating the bureaucratic wrangling over 3G and telecommunication industry reform, there are other government organizations, including the National Development and Reform Commission and Ministry of Science and Technology, involved in the decision process.

(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.

(InfoWorld) - China launched the first trials of a home-grown 4G (fourth-generation) mobile communications network in a district of Shanghai on Sunday, despite the fact it hasn't even decided on standards for 3G (third-generation) services, the Web site of the state-run China Daily reported. The field test in Shanghai's Changning District will cost about 150 million Chinese renminbi ($19.3 million) by the time it's completed and marks an important step for China. It will be the final trial of a system made in China and fulfills a goal ofÂ developing technology at homeÂ to meet the needs of Chinese users. The group of 10 Chinese institutions involved in the 4G project have obtained more than 200 patents for the system since starting research in 2001, and some of its fundamental technologies have been adopted by international standards organizations, the China Daily said, without naming the organizations. The goal has been to put the 4G system into trial commercial use between 2006 and 2010. The 4G system was designed to transmit data and images wirelessly at speeds as fast as landline optical fiber, the China Daily said. Research on the 4G system, called the FuTURE Project, short for Future Technology for Universal Radio Environment, was started as part of China's national high-tech initiative. China hasn't yet released aÂ timetable for the rollout of 3GÂ mobile networks, nor said how many licenses it will issue. Chinese officials have said they want 3G services up and running in time for the 2008 Olympic Games, to be held in Beijing. One issue surrounding the opening of 3G services in China has been the selection of the technology or technologies to be used. Many Chinese officials favor a home-grown standard, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), but a TD-SDCMA rollout could prove slow because of a lack of support from equipment and handset manufacturers.
