Femto Forum ScopeWe 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

“Delivering a great mobile experience to one billion users via femto technology”

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

3G Femtocells Now Outnumber 3G Macrocells Globally!

Global 3G Cells

So what is femto technology?• Standards, chipsets, know-how and other technology

elements delivering scalable licensed-spectrum access 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

Sprint’s Commitment to Small Cells*

Coverage Benefits: traditional macro systems aren’t enough

Cost Reduction: operators must do more with less

Customer Satisfaction:consumers demand high voice and data performance

Conservation: Lower power consumption and extended handset battery life is eco-friendly

Capacity: Targeted capacity where the user demands it.

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

Frequency Assignment Options

• ‘Correct’ configuration depends on existing operator spectrum holdings and the way in which they are used currently

• Starting with a clear channel for femto is common where available, but is not essential

• Ultimately highest spectrum efficiency from avoiding ‘hard’rules, but adjusting according to location and loading

Access mode• In closed mode, may have adjacent

devices on femto and macro which have very different power levels

• Choice of access mode is a key design decision

• Choice may be constrained by regulatory issues and by desired consumer proposition

• Best choice often different between residential (often closed) and enterprise (often open or hybrid)
