NEC Brings a New Solution for Low Cost WDM to Mobile Backhaul

*** For immediate use September 3, 2009

Tokyo, September 3, 2009 - NEC Corporation, a leading provider of microwave and next generation transport solutions, today launched a new wireless and photonic solution for convergent mobile backhaul.

Designed to bring the benefits of WDM technology to legacy and Ethernet transport equipment, the solution features NEC's smart microwave aggregation node (PASOLINK NEO iP) and Transmode's TM-Series Metro WDM systems connected by a coloured fibre connection. The solution finally allows Microwave and WDM to connect in a cost effective way anywhere in the transport network and "management system integration".

The new solution, managed by NEC's integrated Network Management System, brings "lambda multiplexing" technology into every part of the backhaul - allowing unprecedented capacity for wireless broadband networks from base station to core. Using Transmode's Intelligent WDM (iWDM(TM)) and NEC's multiservice aggregation technology, traffic from many base stations can be aggregated on a packet basis by PASOLINK NEO iP, and multiplexed on a per wavelength basis by the TM-Series using a single fibre.

NEC Corporation and Transmode developed the solution to integrate both companies' equipment and ensure the end-to-end continuity of NEC's transport proposition. Integration has demonstrated that Transmode's TM-Series and NEC's Aggregation Switch operate smoothly together, enabling the combination of packet and optical transport. Over 1,000 PASOLINK NEO customers will be able to benefit from this new solution.

NEC's NEO iP and the Transmode TM-Series form part of NEC's end-to-end solution for transport, designed to help customers migrate to more efficient and scalable transport networks. NEC gives customers the choice of transmission media and topology by offering solutions for both microwave and optical transmission under intelligent network control.

Wireless backhaul is effective where no fibre is available, and helps with rapid base station deployment. Where fibre is available, low cost WDM is expected to solve high density 4G capacity issues. NEC provides both in a seamless manner, and with a single management system.

About the NEC Corporation and Transmode Partnership
NEC Corporation and Transmode have a global partnership agreement under which NEC integrates and resells Transmode's Metro WDM optical networking equipment allowing NEC to provide a first class, complete end-to-end solution to its customers.
