2 Key Business Drivers Key Challenges
3 3C Stifling 3G Adoption Coverage, Churn, Capacity Unhappy Coverage Customer Base 3G suffers from inadequate indoor signal penetration Consumer spends ~ 60% - 70% time in indoor environments Poor Coverage = Poor Voice + Poor Video + Lower Data Rates Churn Consumer paying higher price for 3G / HSPA expects high quality of service Poor coverage increases churn Churn = ~ $100/month ARPU Loss + ~ $400 New customer acquisition cost Capacity Indoor users transmitting at high power High Power = Low Battery Life More Cell Sites = Higher OpEx + CapEx Tough to be a 3G carrier Top Line Hit Bottom Line Miss
4 Key Business Drivers Revenue Forecast for US Mobile Users Mobile Broadband Driving Growth Wireless data services are now a $115bn global market, growing at 28% annually, contributing ~2 pts to aggregate telecom services revenue growth outstripping fixed Source: Merrill Lynch 2007 broadband revenues and growth Source: Merrill Lynch 2007 $ M Source: IDC Voice Data TeliaSonera Mobile Broadband Traffic Grew ~ 400% in 1yr 600% 500% TeliaSonera's Data Traffic Growth in % 2 billion mobile broadband users by % 200% 100% Femtocells Accelerate Mobile Broadband Demand 0% Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Source: TeliaSonera at LTE Summit 2008
5 What Is Driving this Growth? Demographics Devices Demand Internet Generation: Years Old Internet-Ready Devices Internet Applications & Content Ideal Conditions for the Perfect Data Storm
6 BUT, Consumers Want MORE for LESS The Era of Flat Rate AT&T and T-Mobile on Tuesday moved quickly to match Verizon's $99.99 all-you-can-eat wireless Following the lead of its competitors, Sprint Nextel Corp on Thursday unveiled a $99.99 pricing plan that gives customers plan, leaving just one big carrier Sprint Nextel on the sidelines.

13 Femtocells Cost Challenge The 4 th C Femtocell is the compelling solution to the 3C Challenge If it can meet the 4 th C = Cost Low per-unit cost for Femtocells is a MUST 4 th C Solutions Software and Silicon Integration Custom silicon addressing femtocell requirements Software integrated with silicon to meet the performance needs CPE Device Convergence STB+Femtocell, Residential Gateway+Femtocell Drives BOM cost down through higher level of integration & component re-use Delivers True Quad-Play: Voice + Video + Data + Mobility
14 CPE Convergence: Fixed / Mobile Operator Example Customer Premises Wireline Secure adsl / FTTX Network ( Mbps) Fixed Voice Internet Access IPTV Mobile Voice Wireless Untrusted Access Network (Security? QoS?) The New Paradigm Secure adsl / FTTx Network ( Mbps) Set Top Box Femtocell Customer Premises Mobile Voice Fixed Voice Internet Access IPTV Femto-enabled STB Compelling IPTV story True Quad-Play Reduced Churn Increased ARPU 100% Secure = more content Managed QoS reused for voice 4 medium blended applications Drives ROI for FTTx build out Huge CapEx / OpEx savings
15 All-IP Network Challenges P2P Traffic - Wireline ISP s Nemesis DPI Service Delivery over All-IP networks Traffic Shaping will P2P traffic clog Mobile Broadband Networks? QoS delivery of real-time voice, video, data over IP network? Securing All-IP networks Security DDoS Ever-emerging New Threats IDS, IPS Unlike wireline, wireless networks are limited by access capacity
16 Traffic Management Challenges IuCS MGW PSTN MSC-Server GMSC Tunneled Iub RNC IuPS Internet NodeB SGSN GGSN IuCS MGW PSTN MSC-Server GMSC FAP Internet Tunneled Iu Security Gateway FGW IuPS SGSN GGSN Internet Direct Tunnel Traffic Offloading
17 Will Wireline DPI Solutions Fit NGMN? Today s Wireline DSLAM CMTS DPI Box DPI Box Bump in the Wire Tomorrow s NGMN Bump in the Wire is NOT right for NGMN Another box additional CapEx, increased OpEx Increases round-trip latency another network hop DPI function MUST be embedded in Femto Gateways Access Networks DPI Enabled Femto Gateways Same problem, but need a different solution
18 Conclusions Key Business Drivers for Femtocells Coverage Capacity Growing Demand for Mobile Broadband Key Challenges for Femtocells Cost CPE Device Convergence Traffic Management DPI! DPI!! DPI!!!
