(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.

The first generation of High Speed Packet Access mobile services increased download speeds to mobile phones. Now carriers are also launching HSPA services, also known as Turbo-3G, with faster upload speeds, making the mobile office even more of a reality.On Thursday, AT&amp;T Wireless unveiled two new LaptopConnected HSUPA (High-Speed Uplink Packet Access) data cards for its wireless broadband customers.Another carrier that has upgraded its network and recently launched a service is 3 Sweden.&quot;We are mainly talking to professional users. It&#39;s a really good service for people that need to send large files,&quot; said Camilla B&#252;low.It charges a flat monthly fee of 299 Swedish kronor ($46) for the service, aptly named Pro.AT&amp;T Wireless and 3 Sweden are not the only operators speeding up their networks. Around 50 carriers currently support HSUPA, according to the latest figures from GSM Association, a group representing network operators.&quot;Moving to HSUPA is a logical progression, and it doesn&#39;t take a substantial investment to upgrade,&quot; said David Pringle, spokesman for the GSM Association.Heavy e-mail users aren&#39;t the only ones who have a lot to gain from faster upload speeds. In a world where consumers create more of their own content and make phone calls from the PC, and where the move to delivering software as a service is gaining momentum, faster upload speeds are becoming increasingly important.&quot;We are doing a lot of work around virtual desktops, and faster network speeds in both directions would improve the mobile user experience,&quot; said Peter S&#246;derholm, field systems engineering manager at Citrix Systems Nordic.The first iteration of HSUPA supports theoretical data rates of up to 1.4Mbps. In the real world that means around 1Mbps -- three to four times faster than existing networks. Next year the speed will increase to up to 5.76Mbps, and carriers are getting ready for that too.&quot;Our network is ready for that speed, but we haven&#39;t said when we are going to upgrade,&quot; said B&#252;low.For the technology to become useful, users must have compatible modems and phones. Modems are becoming more common, but mobile phones are still scarce. HSUPA products launched at last week&#39;s Mobile World Congress included Sony Ericsson&#39;s Xperia X1 and Toshiba&#39;s Port&#233;g&#233; G810.&quot;The phones are a bit behind,&quot; B&#252;low concluded.

(InfoWorld) - South Korea's LG Electronics and Samsung Electronics onÂ Tuesday demonstrated a technology upgrade for WCDMA (Wideband Code Division Multiple Access) networks that will allow for much faster upload speeds. Most current 3G (third generation) mobile networks based on WCDMA offer maximum uplink and downlink speeds of 384Kbps. The downlink speed can be increased with the use of HSDPA (High Speed Downlink Packet Access), which allows downloads at speeds of 3.6MbpsÂ or more. Both LG and Samsung took advantage of the International Telecommunication Union (ITU) Telecom World 2006 show in Hong Kong to unveil prototype HSUPA (High Speed Uplink Packet Access) systems. LG expects to make HSUPA technology in handsets available during the second half of next year, said Choi Hyung Keun, a research engineer at LG's Mobile Handset R&D Center. Engineers at LG's research and development labs have gotten uplink speeds of up to 2Mbps using HSUPA, with average throughput at around 1.5Mbps, Hyung said. However, LG believes this speed can be increased. The technology is theoretically capable of speeds up to 5.8Mbps or so, he said. Samsung's HSUPA technology is also now capable of uplink speeds up to 2Mbps, the company said. The increase in uplink speed reduces the time a user takes to upload five MP3 files from five minutes with WCDMA to one minute with HSUPA, it said. Samsung plans to build its first HSUPA systems in Europe during 2007 for Orange SA and other operators. Telecom World runs through Friday.ADVERTISEMENTNEW IT SERVICES FROM IBM: EASIER TO BUY AND IMPLEMENTDiscover a simpler, more cost-effective way to get the solutions your company needs to grow more flexible and efficient.
