4G Wireless: 2.5Gbps: Japanese researches break record

Researchers for Japan's largest mobile operator NTT DoCoMo, have broken a world record for packet-switched data transmission in a mobile network. The researcher's achieved 2.5Gbps packet transmission downstream while moving at 20 kilometers an hour. According to the report, DoCoMo achieved 1Gbps speed in a similar field experiment last year; This time, by increasing the number of MIMO transmission antennas from four to six and by using 64-QAM, they increased data volume per transmission from four bits to six bits.

Sounds intersting, but I wonder when this technogy enhanvements will reach the United State, and even if they will ever make it there; ther just seems to bee this feeling that certain technologies in Japan would not be popular here in the United States. This is not allways the truth. There are many technologies, including 7 MegaPixel Cameras, that would be great to be shipped here.
