O2 Nortel Networks role in pan-European UMTS network build

Pro

1 April 2005

O2 is rolling out infrastructure products from Nortel Networks to enable it to provide third generation (3G) wireless services in Ireland, Germany and the UK.

The company is currently working on infrastructure rollouts to expand 3G network coverage into new regions. O2 plans to by offer advanced data services like mobile e-mail, video calling, mobile Internet browsing, and Multi Media Services (MMS) including
streaming video and localised, personalised content, through its 3G network.

Nortel Networks will supply O2 with products from its Base Transceiver Station (BTS), Mobile Switching Centre (MSC), Radio Network Controller (RNC), and Data Packet Core (GGSN, SGSN) technology portfolios. Nortel Networks wireless equipment is designed to easily migrate with cost-effective, modular upgrades to support higher bandwidth 3G technologies. This can eliminate the costly need to replace hardware and streamline deployment to speed time-to-market for services.

Nortel Networks has previously supplied O2 with equipment for its GPRS and UMTS core networks. Nortel will also provide some network engineering and radio optimisation services. The contract extension expands the scope of an existing supply agreement signed by Nortel Networks and O2 on October 31, 2002. Nortel Networks was selected as one of two infrastructure suppliers in April 2002. At that time, O2 stated that additional deployments would be awarded based on performance at a later date. This latest contract is with mmO2 Limited and O2 Operating Companies (O2 UK, O2 Ireland and O2 Germany). O2 is a subsidiary of mmO2.
