NTT DoCoMo Begins Super 3G Experiment

NTT DoCoMo, Inc. began testing an experimental Super 3G system for mobile communications this month. With this experiment, DoCoMo seeks to achieve a downlink transmission rate of 300Mbps over a high-speed wireless network. Super 3G features low-latency data transmission and improved spectrum efficiency. It is a highly advanced version of High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA), which have been evolved from W-CDMA packet transmission technologies standardized by the 3rd Generation Partnership Project (3GPP). The 3GPP, a telecommunications standards organization, is currently discussing standardization of Super 3G under the name Long Term Evolution (LTE).

DoCoMo, aiming to achieve sustainable, efficient use of 3G spectrum resources, is leading the discussion over LTE. DoCoMo believes Super 3G will allow the company to make a smooth transition to 4G in the future.
In July 2006, DoCoMo began accepting proposals from suppliers seeking to develop Super 3G equipment and expects to complete development of Super 3G technology by 2009.
