NEC Selected as Vendor for NTT DoCoMo's Super 3G
Wireless Base Station Equipment

*****For immediate use December 10, 2007

NEC Corporation has been selected as a vendor for the development and manufacture of Super 3G wireless base station equipment to be used in new commercial services offered by NTT DoCoMo, Inc.

Super3G is a standard system and an advanced version of the W-CDMA-extended technologies HSDPA(1*) and HSUPA(2*). The system, which achieves outstanding 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.

Super3G has been under discussion by the W-CDMA standardization organization 3GPP(3*) as part of "Long Term Evolution"(4*), and most of the main specifications have been determined. NEC plays a central role in these standardization activities, having dispatched two Vice-Chairmen and numerous other participating members.

NEC has been providing NTT DoCoMo with infrastructure systems for some time as a leading total mobile solutions provider. The solutions range from mobile handsets and i-mode(TM)(5*) service platforms to core networks and wireless base stations. In addition, NEC has already been selected as a vendor for Super3G mobile handsets.
NEC believes its selection as a vendor for the development and manufacture of Super 3G wireless base station equipment can be attributed to NTT DoCoMo's high regard for its extensive track record as a total solutions provider in the mobile area.

NEC will continue to strengthen its relationship with NTT DoCoMo, and to contribute to the further development of next-generation mobile technologies by providing cutting-edge mobile solutions for the global market.

Notes

(1) HSDPA (High-Speed Downlink Packet Access) is a technology that dramatically increases downlink communication speeds; standardized by 3GPP as an advanced version of W-CDMA to meet demands for high packet communication speeds. Theoretically, this technology can achieve high downlink communication speeds of up to 14Mbps.

(2) HSUPA (High-Speed Uplink Packet Access) is a technology that dramatically increases uplink communication speeds; standardized by 3GPP as an advanced version of W-CDMA to meet demands for high packet communication speeds. Theoretically, this technology can achieve high uplink communication speeds of up to 5.7Mbps.

(3) 3GPP (3rd Generation Partnership Project) is a partnership project involved in creating detailed specifications for IMT-2000 W-CDMA. Standardization organizations in various countries and regions have adopted the standard specifications created by 3GPP. The Project's many members include the world's foremost mobile communication carriers.

(4) Long Term Evolution (LTE) is the name used to refer to 3GPP's standards for Super3G.

(5) i-mode is a treadmark or registered trademark of NTT DoCoMo, Inc. in Japan and other countries.
