(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) - 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.
