Significant Momentum for LTE Small Cells

AT&T “launches RFI for Small Cells” ...up to 100,000 units (Light Reading, June 21, 2012) “AT&T has been an advocate of small cells for several years, and we’ve spent a lot of time with our vendors working on a strategy for deployment” – Kristin Rinne, SVP, Architecture & Planning (speaking at CTIA Wireless trade show May 9, 2012)

Planning on deploying small cells to enhance LTE capacity

– Hans Leutenegger, VP of Network: South Region (speaking at CTIA Wireless trade show May 2012)

“The end goal of our plans is a completely heterogeneous network. Small cells are a fundamental part of this.” over 600,000 residential femtocells today; moving to indoor small cells this year and outdoor small cells “to add much needed capacity” in 2013 – Iyad Tarazi, VP Network Engineering (May 2012)

FCC

· Announced launch of small cells for residential & enterprise across Europe & Latin America · Now deploying multi-mode small cells for LTE

Opens up 100MHz for small cell LTE (3.5GHz – 3.6GHz)

Small Cell SoC TAM to Reach $1 Billion in 2016

Market forecast to grow from <$100 million in 2012 to over $1 billion in 2016*

Informa predicts 91 million small cells deployed by 2016

– 4.6 million small cells currently deployed

– By the end of 2012, there will be 6.4 million small cells outnumbering the forecast 6 million macrocells worldwide

Currently, 43 small cell commercial deployments in 23 countries

Motives for Small Cell Deployments

Future: Applications and New Services

Problem: - Data loads exceeding capacity - Limited macro expansion ability - Increase capacity economically

by offloading to femtocells

Small Cells: - Provide localized capacity - Expand overall capacity/ARPU - Clear acceptance and support

from carriers - Benefit: Increase capacity,

increase customer satisfaction with lower CapEx, OpEx

Cap

acity

Problem: - Basic RF coverage holes - Particularly affects affluent homes - Requires improved voice coverage - Rural areas “Greater Femto”

Femtocells: - Provide basic service coverage - Primarily residential - Some success stories (eg SPRINT,

SFR) and carrier support - Benefits: reduce churn, increase

customer lifetime value

Revenue vs. Traffic Growth

Voice Era

Data Era

Traffic is more than doubling every year (Cisco MVNI 108% CAGR) ARPU flat: Carriers need to increase capacity and efficiency

Capacity: Technology Reached Limits

11

Increase performance

Cooper’s Law: increasing the number of cells has always been the primary way to add capacity

Need more cells and tighter interference control (HetNet, SON) to increase capacity

Most gain from shrinking cells

Shrink cell

“Spectral efficiency can improve capacity by 1.5x. Spatial efficiency Increases capacity by 10x or more” - Alcatel-Lucent

12

Small Cells and WiFi – Solving Problems Together

All operators now require WiFi with their pico / metro cells WiFi alone is insufficient for carriers

– Short range requires too many sites, not economic compared to WiFi + cellular small cell

– Poor performance and customer experience concerns Multi-mode dramatically

improves economics – Increase usage, value – Minor impact on CapEx – TCO dominated by per site,

power, backhaul

Best of Breed Outdoor Wi-Fi

Economic Drivers for Small Cell Deployments

13

Hierarchical Cell Structure / Self-Organizing Network / HetNet

Mobile Experts Macrocell is 2.5x – 8 x

more expensive than a small cell

Signals Research (Carrier Data Costs) Macro = $8/GB Small cell = $5/GB Femto cell = <$1/GB

Small cells reduce mobile network operator CapEx, OpEx and TCO

Telefonica: Small Cells Across Europe & LatAm

14

Triple mode: 3G HSPA + WiFi + 4G LTE

“Small cells are the only way for future capacity, even factoring in extra spectrum and LTE-A” -- Robert Joyce, Chief Radio Engineer

Vodafone Committed to Small Cells

15

• Small cells increase coverage and reduce churn • Core part of marketing strategy • Improved customer satisfaction: 96% “would

recommend” • Small cells as dominant part of LTE deployment

AT&T: Largest Deployments to Date

16

AT&T launched residential femto service in March 2010

Several hundred thousand deployed – Informa estimates 800,000

Emphasis on coverage and churn reduction

Light Reading reported RFI for 100,000 multi-mode small cells for 2013
