Partners Operators Technology providers

66 operators covering 1.99 billion mobile 71 providers of femtocell technology subscribers – 34% of global total

Femto Forum Scope We support the whole range of small cell applications enabled by femto technology.

Femto Technology = chipsets + standards + know-how and other technology elements delivering scalable licensed-spectrum access points for mobile services This technology has been created via the advent of residential femtocells, but enables a much broader range of small cell applications

4 112% Growth in Deployments in the Last Year Eight of the top ten operator groups by revenue now offer femtocell services

5 3G Femtocells Now Outnumber 3G Macrocells Globally!

Global 3G Cells

6 So what is femto technology? • Standards, chipsets, know-how and other technology Femto elements delivering scalable licensed-spectrum access Technology points for mobile services • Developed originally for residential applications, where consumer electronics volumes enable and require a customised, highly intelligent approach • So why are small cells different with femto technology? • Key attributes: - Scalability - Automated configuration and optimisation - Rapid, cost effective deployment - Efficient use of available backhaul - High capacity density and user experience

7 Applications of femto technology An increasingly wide range of femto-enabled small cells Femto Forum works to enable and promote all of these

Yearly deployments in the thousands expected. Customer Satisfaction: consumers demand high voice and Indoor PicoCell Applications data performance Med/High power, carrier provided backhaul Conservation: Lower power Wimax deployed 2011 consumption and extended handset LTE coming in 2012 battery life is eco-friendly

Outdoor PicoCell Applications Capacity: Targeted capacity High power, carrier provided backhaul where the user demands it.

* 4G World October 25, 2011 Frequency Reuse: Macro and Femto Dense frequency reuse is essential to sustain the mobile industry • The ‘central magic’ of cellular systems is the ability to accommodate an unlimited quantity of demand (users or bits) in a limited quantity of spectrum • This is enabled by careful and appropriate management of interference amongst cells: so (managed) interference is a good thing! • Continuing growth means that only smaller cells can meet the demand sustainably and economically Strong Operator Interest in LTE Small Cells > 60% of operators surveyed consider small cells will be more important to LTE deployments than macrocells

13 Frequency Assignment Options

Femtocells (a) • ‘Correct’ configuration depends Macrocells on existing operator spectrum Frequency f1 f2 f3 holdings and the way in which they are used currently Femtocells (b) Starting with a clear channel for Macrocells • Frequency femto is common where f1 f2 available, but is not essential Femtocells

(c) • Ultimately highest spectrum Macrocells Frequency efficiency from avoiding ‘hard’ f1 f2 rules, but adjusting according to Femtocells location and loading (d) Macrocells Frequency f1 f2 Access mode Closed Mode • In closed mode, may have adjacent Only users on white list devices on femto and macro which can access femtocell have very different power levels • Choice of access mode is a key Hybrid Mode design decision Users on white list have priority access to • Choice may be constrained by femtocell, but all users can regulatory issues and by desired access if capacity available consumer proposition • Best choice often different between residential (often closed) and Open Mode All users can access enterprise (often open or hybrid) femtocell Spectrum Possibilities with Femtocells Femto Services
