NTT DoCoMo said they hit nearly 5 Gbps between a transmitter and receiver, with the receiver moving at 10 km/h: A year ago, they hit 2.5 Gbps. The new device doubles MIMO antennas from 6 to 12 and improves signal processing. The same 100 MHz of spectrum was used. The company will release details at next week's 3GSM World Congress in Barcelona, Spain. 4G was thought to be slated to launch as early as 2010, but a Super 3G flavor of WCDMA will precede it with 100 Mbps speeds by 2010.
