DoCoMo has been running tests on 4G network speeds and have announced a 2.5Gbps download speed while traveling at 20kmh speed. Bypassing 3G upgrades such as HSPDA, DoCoMo jumped straight into the development of 4G. Its system uses modified standards proposed by the International Telecom Union (ITU), which improves upon transmission speed. It uses 6 simultaneous transmissions with 6 antennas and an advanced encoding algorithm to achieve this high data rate.
