NEC Starts Delivery of New 3G Node-B Series with High-Scalability, Realizing Smooth and Swift Deployment of 3G Services.

Tokyo, Japan, Dec 27, 2006 - (JCN Newswire) - NEC Corporation (TSE: 6701) announced that it has started delivery of a new 3G (W-CDMA) Node B series "RS381, RS880." Boasting high-scalability, the new series is expected to contribute to the realization of smooth and swift expansion of 3G coverage area.

The new series features Remote Radio Head (RRH) architecture, which divides the Node B into a main controller and a compact RRH outdoor unit. This allows flexible installation as the RRH outdoor unit can be installed within several dozen kilometers of the site, enabling response to a variety of situations and conditions.

The new series also allows flexible configuration as the RRH and main controller can be connected by optical fiber. Typical configuration incorporates installation of main controllers with a central switching system and RRHs are then deployed in each of the service areas. Another method consists of several small RRHs being separated from the main controller and installed indoors and at other locations where radio coverage is weak in order to secure stable coverage. NEC's new 3G Node B series overcomes this issue of difficult configuration, realizing smooth and swift deployment of Node Bs, in turn expanding 3G coverage areas. Moreover, it reduces installation time to one quarter that of typical installation methods.

The new Node B products have been developed jointly by NEC and Siemens.

NEC is ready to deliver its new HSDPA to commercial networks worldwide, and has started delivery of the new product to Softbank Mobile. Softbank Mobile has announced plans to increase its Node Bs by March 2007 and NEC's new 3G Node B series is expected to play a vital role in their plan.
