(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) - NTT DoCoMo will partially fund the construction of AT&T's 3G phone network in Hawaii, it said Thursday. The unusual agreement will see NTT DoCoMo, Japan's largest cellular carrier, provide AT&TÂ with $24 million to help it build the network. The network will be based on WCDMA (Wideband Code Division Multiple Access) and AT&T will launch service on the island of Oahu late this year and statewide in 2008, NTT DoCoMo said in a statement. Hawaii is a major holiday destination for Japanese tourists but most NTT DoCoMo customers can't use their cellphones on the island. That's because the carrier's 2G handsets are based on a proprietary standard used only in Japan and because in most 3G phones it has left out GSM (Global System for Mobile Communications) compatibility leaving only 3G for overseas roaming. Because the proprietary 2G format kept many previous handsets offline many consumers aren't used to it and don't look for it when buying a new handset. Although that's slowly changing as more experience the convenience of using their phone overseas for the first time. NTT DoCoMo said it will work with AT&T to promote roaming in the U.S. as a result of the deal. Last year NTT DoCoMo made another investment in the Pacific when it acquired Guam Cellular & Paging and then used that company to acquire Guam Wireless Telephone Company. The investments, which totaled about $72 million, were made to speed up the introduction of WCDMA on Guam and help its roaming business. Guam is another major tourist destination for Japanese people.
