Fujitsu Ltd and NTT DoCoMo Inc. announced they have developed prototype wireless base station equipment with a maximum downlink transmission speed of approximately 900Mbps throught the application of MIMO technology.

The companies partnered in November 2006 to develop prototypes and commercial equipment DoCoMo's "Super 3G" wireless base stations. Super 3G is DoCoMo's next-generation specification for a wireless system for broadband communication over a mobile phone. To bring about dramatic improvements in performance, such as increasing the speed of data transmission, shortening connection delays, and improving efficiency in the use of the spectrum, the 3GPP international standards organization is working on creating a new standard specification called LTE.

Since being selected to develop and manufacture DoCoMo's Super 3G wireless base station equipment, Fujitsu and Fujitsu Laboratories have worked with DoCoMo in developing the required technologies, and the companies have succeeded in developing a prototype wireless base station that achieves maximum downlink transmission speeds of approximately 900Mbps when using four antennas each (4x4 MIMO) for Super 3G base station transmission and mobile station reception as well as employing Fujitsu Laboratories' short-delay, high-speed error correction decoding technology.

Going forward, along with applying the results of development and evaluation work on MIMO and other Super 3G prototype technologies, Fujitsu will work to further refine the high-efficiency amplifiers and high-performance baseband processing technology it has developed for 3G wireless base station equipment in order to develop optimized commercial Super 3G wireless base station equipment that is compact, energy-efficient, economical, and highly scalable.
