End-users want 3G services at a reasonable price
Market Trend Operator challenges
• Regulators are opening 900 MHz band for WCDMA
• WCDMA 900 MHz terminals arriving to market
• HSPA services are operator key assets
• Most HSPA usage comes from indoors
• Data pricing typically based on flat rate
• Demand for 3G coverage is growing
• Voice ARPU decreasing
Successfully accommodate WCDMA into the GSM/CDMA/TDMA bands
Guaranteed high speed data services for indoors
Cost efficient WCDMA network expansion and operation

WCDMA refarming to 900 MHz frequency band
• Introduction of 3G services into frequency band that is already used for other technology, like GSM
• In order to fit the WCDMA carrier into same bandwidth, typically spectrum efficiency needs to be improved

WCDMA 900 MHz can be used today
• All major WCDMA chipset platform vendors support WCDMA 900 MHz
• Operator requirement for WCDMA 900 MHz capable terminals growing
• WCDMA 900 MHz devices arriving to the market
“ There will be data cards and USB modems very soon from all the vendors”
“ Next year, UMTS900 will be an available feature in a significant number of the 3G terminals sold in Europe, and in 2009, UMTS900 will be a standard feature.”

What to consider when deploying WCDMA 900 MHz
Nokia Siemens Networks’ WCDMA Frequency Refarming Solution taking into account all needed aspects
• Careful frequency planning and network optimization
• Implementation of GSM spectrum efficiency functionalities
• Minimized frequency need for WCDMA carrier
GSM capacity
GSM capacity & service quality must remain unchanged
• Different GSM/WCDMA handover options
• Traffic balancing between GSM and WCDMA cells
Interworking
Smooth GSM/WCDMA interworking to ensure high user experience
• Common management system for both GSM and WCDMA networks
• Automated joint network management
New technology in same frequency band complicates the network management

Elisa Finland launched world's first commercial WCDMA 900 MHz network (8 November 2007)
• WCDMA 900 network launched in 2 areas in southern Finland
• Target to cover 75% of Finns with 3G services at the beginning of 2008
• Data rates are at beginning up to 2 Mbps and 2008 planned to be increased close to 10 Mbps
Nokia Siemens Networks press release, November 8, 2007
“Thanks to the Nokia Siemens Networks frequency refarming solution, we are now running WCDMA and GSM efficiently in our 900 MHz frequency allocation, enabling us to extend our 3G services cost-effectively from cities to the less populated areas of Finland.”
