  • 3. The Big Picture Apple sold 7.4M iPhones in Q3 Intel reports blowout Q3 on strong mobile business; Atom rev up 14% AT&T sells Nokia netbooks for $300 with 2 year contract Verizon’s CTO: “Metered broadband is the future” And… Operators need… Traffic Revenues & Femtocells = Traffic Gap Cheapest Widening Bit Pipe Voice Era Revenues Data Era LTE = Fastest Bit Pipe DPI = Smartest Bit Pipe The “Exa-Flood” is Coming… Confidential and Proprietary 3
  • 4. LTE Momentum GSA, the Global mobile Suppliers Association, confirms 42 LTE network commitments in 21 countries GSMA predicts that 14 LTE networks will be in service by the end of 2010 growing to more than 30 by the end of 2012 According to Light Reading, LTE products have been tested, trialed and commercially announced in the market by more than 75 vendors Confidential and Proprietary 4
  • 5. LTE RAN Options Macro network Multi-sector, broad coverage High-speed mobility Small cells Pico / Micro / Femto Broadband experience “Inside out” deployments 60% - 70% of time indoors Targeted in-building services offerings Confidential and Proprietary 5
  • 6. Femto’s Role in LTE Coverage LTE Femtocell Solution Greater indoor signal strength Targets early Provides LTE coverage Small cell deployment for mesh adopter users Low-power & self-configuring to demanding minimize interference coverage increased Aligns with LTE standards performance Leverages users’ broadband Churn Consumers expect higher quality of service Poor performance increases churn Capacity Less users / shared channel LTE LTE macro LTE femtocell metro Closer to cell = better signal base station femtocell converged device Confidential and Proprietary 6

  • 11. SON: Golden Goose, Needed Standard, or Both? Self Configuration IP Extend TR-069 / TR-196 HeNB ACS Static and dynamic, zero touch Self Optimization Beyond interference minimization Coordinated optimization among cells Dichotomy “Golden patent” vs. standards Algorithms vs. messaging Confidential and Proprietary 11
  • 12. Backhaul, Everybody’s Problem “Exa-Flood” is jamming the pipe Already a challenge today Common hurdle for all wireless technologies Residential issue Need FTTH / FTTC Happening… but fast enough? Metro issue Local fiber loops Leverage fixed WiMAX Smart pipes Backhaul optimization leveraging DPI Internet Offload applications Confidential and Proprietary 12
  • 13. LTE Femtocell Deployments Initial LTE deployments not using femtocells Verizon, NTT DoCoMo have expressed interest Solutions are not ready today Good for the LTE Femtocell Small cells as overlay to macro networks Time for diversity of devices to grow LTE femtocell as THE DIFFERENTIATOR Boost to performance Improved QoE for first wave of early adopters Confidential and Proprietary 13
  • 14. Example LTE Deployment 2G 3G LTE 2010 2020 • LTE Network Overlay • Long Term: 3G migrates to LTE • Existing 2G / 3G Network for Coverage • 2G to Support Roaming • LTE Femto for Capacity • LTE Macro for Coverage Confidential and Proprietary 14
  • 15. LTE Femtocell Report Card Hurdle Grade The Good The Bad Silicon C+ Aggressive roadmaps Min 12-18 months away from Tier 1 femto entrants integrated silicon Standards C+ Architecture standard Ability to focus efforts in 3GPP Specific work item in 3GPP SON D/B Public and private investment Limited standards efforts Backhaul B Primarily an investment issue Expensive and required Backhaul optimization tech Deployment B+ 42 commitments In-service vs. broad coverage 14 networks by end of 2010 A = ready today B = ready within 12 months C = ready in 12 to 36 months Field Trials ~ 12 to 18 Months D = greater than 36 months Deployments ~ 24 to 36 Months F = no solution in sight Confidential and Proprietary 15
  • 16. Conclusions Benefits of small cells for LTE remain seductive Better performance and QoS Unmatched QoE Staged, hotspot deployment models Industry mobilizing to deliver solutions 12 to 24 months away from “field trial”-ready ecosystem Investments being made in all key technology areas Let’s not forget the 3G femtocell, either 3G femtocells available today LTE femtocell is not necessarily the “upgrade” Confidential and Proprietary 16
