4G

This puts NTT DoCoMo squarely in the forefront of 4G technology -- the speed record, the company says, was achieved by increasing the number of Multiple-Input Multiple-Output (MIMO) transmission antennae from four to six, and by using 64-Quadrature Amplitude Modulation (QAM), which increased data volume per transmission from four bits to six bits.
And as Techworld.com points out, this is a vast improvement on NTT DoCoMo's last 4G demonstration earlier last year, in which the carrier reported that it had achieved speeds of 1 Gbps.
