March 27, 2008- DoCoMo has a very proud announcement to make. They have successfully achieved a downlink transmission rate of 250Mbps via high speed wireless networking. During an experimental outdoor test of their Super 3G mobile communications system, their achieved the world’s fastest mobile network! DoCoMo has been trying for such an achievement for a while. Several field tests have been performed before this most recent, successful one in R&D labs in Yokosuka, south of Tokyo. Beginning in February, DoCoMo has been trying to capture excellent speeds for their networking and has finally reached success.

During their testing, DoCoMo has used four Multiple Input Multiple Output (MIMO) antennas for transmitting from base stations and receiving at mobile stations. They have been utilizing maximum Super 3G standards at a 20MHz bandwidth. They are continuing to test connection handover between base stations. Also, they have been working to improve the functioning of applications when used indoor as well as outdoor.

Super 3G, also known as Long Term Evolution (LTE) features low latency for all its data transmissions and also has high spectrum efficiency, which is truly the point at which they are outshining all others. This goes above and beyond High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA). DoCoMo began in mid-2006 accepting proposals from those who wished to utilize Super 3G test equipment. They are currently planning to complete development of the technologies by 2009 and begin launch of this new, extraordinary network option. Test results will be presented at CTIA Wireless 2008.
