The development followed the company’s decision to increase the number of MIMO transmitting and receiving antennas from 6 in a December 14, 2005 test, where the maximum speed reached 2.5Gbps, to 12. The ratio of data transmission rate to channel bandwidth from the previous to the latest testing also increased two-fold from 25bps/Hz to 50bps/Hz (5Gbps/100MHz). DoCoMo plans to report the experiment’s details before the 3GSM World Congress 2007 in Barcelona, Spain.

With thier interest in 3g and the Japanese market for such a service, it’s no wonder that NTT DoCoMo is looking into the technology.
