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

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

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

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

8. The Five Key Hurdles
1) Integrated Silicon
2) Standards
3) Self Organization and Optimization
4) Backhaul
5) Deployments

11. SON: Golden Goose, Needed Standard, or Both?
Self Configuration IP

ACS
Static and dynamic, zero touch
Self Optimization
Beyond interference minimization
Coordinated optimization among cells
Dichotomy
“Golden patent” vs. standards
Algorithms vs. messaging

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

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

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

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

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”
