Fujitsu to produce 900 Mbps Super 3G Base Station

DoCoMo and Fujitsu Laboratories Limited have made progress in jointly developing a prototype wireless base station equipment, allowing the tests to acheve a maximum downlink transmission speeds of approximately 900 Mbps.

In November 2006 NTT DoCoMo selected Fujitsu to develop and manufacture prototypes and commercial equipment for DoCoMo's "Super 3G" wireless base stations.

Designed to replace DoCoMo's current 3G mobile phone system (FOMA), Super 3G is DoCoMo's next-generation specification for a wireless system for broadband communication over a mobile phone.

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 900 Mbps 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.
