Both WCDMA and EDGE radio technologies with GPRS will be needed tomeet the mobile network capacity requirements

Challenge

• Small amount of GPRS trafficcan be handled by existingidle radio network capacity,but:

• Busy hour voice traffic loadsjeopardize the GPRS serviceperformance

Nokia Estimates

•To be added for initial GPRS use:Urban Cells: 3 timeslots/sectorSemi-urban cells: 1 timeslot / sectorRural cells: 1 timeslot / sector

•Overall implication is 3%capacity expansion to theinstalled transceiver base

Advanced Phase:WCDMA and EDGE in parallel use

• EDGE: tripled dataspeeds and capacity foreach channel comparedto basic GSM

• EDGE typically provides50% more combinedsite capacity

3G imminence

WCDMA 3G is on track for 2H/2002commercial launches

Mobile Middleware and Services• Mobile middleware platforms built for GPRS will convert to 3G• Multimedia Messaging Service infrastructure ready in time for

WCDMA 3G launches in 2H/2002

Mobile Networks• WCDMA Network infrastructure volume rollout is under way• Volume deliveries of both RAN and core equipment started in

September 2001• Network upgrade to commercial Rel99 June01 version in early

2002

Mobile Terminals• Nokia will bring dual mode GSM/WCDMA terminals in volumes

in 2H/2002

Nokia Confirms the EDGE Time Schedule

• No changes to core network required, UltraSite and MetroSite basestations are upgradeable to EDGE

• EDGE hardware available from 4Q/2001 in America (800/1900) andfrom 2Q/2002 in Europe and Asia (900/1800)

• Full commercial software support in networks from 2H/2002

• Nokia Mobile Phones will bring EDGE terminals to the market inline with Nokia Networks’ network rollout capabilities

Timelines for 3G implementation

• EDGE is preceding WCDMA in North-America as ideally suited forlocal frequency allocations

• By adopting GSM/GPRS/EDGE early, TDMA and CDMA operators canalso secure the benefits of powerful economies of scale
