8. Understanding the Economics of Wireless Revenue = ( ARPU, Penetration, Subscriber Mix) ARPU, Penetration =  ( Handsets, Content, Applications) Handsets Enable Content Content /Applications Drives Traffic Traffic Drives ARPU Wireless Operators looking for: • Compelling Services Offering • Easy data application Deployment • How to introduce wide range of applications in short time frame and still insure good end-user experience?

9. CDMA 450 Marketing opportunities Premium Voice Quality • State of the art noise cancellation High speed data offering • Up to 156 kbps available, faster than dialup • Average 70 kbps when network is loaded • VPN services to the corporate network from any covered area Data applications & services • PTT, LBS –gpsOne, Brew • 1000’s of applications targeting all consumers • Flexible data billing models 3G Ready!

10. ARPU & Penetration=  (Applications) Traffic Information (Updated every 5 min.) Music Video & Movie Clips Powered byNATE Media Player(Supports H.26L technology) Online Game (e.g. Tetris Competition) NATE Access Game Category Select Tetris Select Level Select Partner Compete Content drives traffic

11. Global 1X Data Subscribers (3Q03) • Approx 27.5M 1X data subs (GPRS ~26.8M) • Majority of 1X data subs in Korea & Japan • Data is becoming a significant % of ARPU Asia Pac87% CALA 5% North America 8% Source: EMC, 3GToday Broadband Wireless is the Future

12. Customer Service RECORD REPLAY Two Generations of Data ApplicationsInnovation (Devices +Content +Applications) = Enhanced User Experience 1xEV-DO 1X • Video messaging • Video [News/TV] on Demand • Record & send Video Clips • Email Video Clips • Multi-media messaging • DSL-like Corporate access • Interactive Gaming • Music Video Downloads • Interactive Map & Location Services • Voice/Text messaging • Text [news/browsing] • Take Picture (still image) • Email Pictures • Single Media • Dial-up Speed Corporate access • Gaming • Music Downloads • Text based directions Enhanced interactive, multi-media and video applications to deliver superior end-user experience

13. 1xEV-DO Delivers A Superior Data User Experience High Speed Thrills and Delivers • Broadband mobility • Up to 2.4 Mbps peak data • Dedicated data-optimized carrier • complimentary to 1X Data and voice resources don’t compete • 1.25 MHz spectrum 1X and 1xEV-DO functionality Comparable to UMTS with much less spectrum Multimedia Services Email with Large Attachments Video/Audio Streaming Interactive Color Gaming Mobile Office Infotainment On Demand • Web Browsing • Screen Savers • Bookings/ • Transactions 2.4 Mbps 3x – 6x CapacityIncrease over 1X Stock Quotes 154 kbps 9.6 kbps

14. 1xEV-DO Wireless Residential BroadbandExpand subscriber base and usage Always On Broadband2.4 Mbps peak downlink One device – home and on the road One bill, one account Easy to installNo truck roll Profitable Up Sell Reliable Wireless Wide Area Network Leverage existing installed mobility network investment Secured Access

15. + + Application Service Delivery Platform CDMA Infrastructure PTT Application for CDMA 450 in Europe • PMR/PAMR is key requirement for CDMA 450 in Europe • PTT (Push To Talk) provides for PAMR like functionality • One way broadcast of voice (Half-duplex) • Packetized voice over wireless data network • Supports person to person (i.e. 1 to 1 walkie-talkie) as well as person to group messaging (1 to many broadcast) • Instantaneous connection • Simple user interface (select called party via buddy list or short code, push a button and talk) Speak Release Push Release Push Respond = PTT Solution

16. E-Mail Mobile Device Manager VPN’s Middleware Content Management Acceleration MMS Packet Streaming Video Telephony Push-to-Talk Brew Enabling Applications via Solution Partners
