NEC has been selected by NTT DoCoMo to provide core network “EPC” systems that support NTT DoCoMo’s “Super 3G” next generation mobile phone networks. Super3G is a standard system and an advanced version of the W-CDMA-extended technologies HSDPA and HSUPA. The system, which achieves data transmission speeds of 100Mbps or more in downlink and 50Mbps or more in uplink access, is designed to reduce delays in data transmission and improve frequency usage efficiency.


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
