Macrocells are very bad at in-building coverage

Poor coverage is #1 cause of churnBusiness case relies on high-speed data where people want to use it

Femtocells can enable this

FMC, VoWiFi The threat for cellular operatorsThe threat for cellular operators

Wireless market saturated -operators need new strategies tooperators need new strategies to drive ARPU and gain customers

Threats from new entrants (MVNO,Threats from new entrants (MVNO, Voice-over-WiFi)

Strong desire to shift users to 3G (or other data services)But… 3G coverage is lousy indoors (especially for data)

Femtocells allow Wireless operators to (profitably) compete with voice-over-WiFi

Benefits to Consumer Benefits to Operator

Reduces cost (free calls!)FEAR:

Counters threat from VoIP &educes cost ( ee ca s )Improves coverage;no deadspotsSimplicity: single Device,all numbers in one place

Counters threat from VoIP & UMA

GREED:Increases both coverage and capacityp

No need for expensivenew device

capacityReduces churnIncreases ARPU (sell BB too)Works with all existing handsets;

d f i b idino need for expensive subsidies on dual-modeIncreases 3G adoption

By 2011 there are forecast to be 180 million femtocell users, with 60 million devices. y ,Femtocells will be an integral part of the operator push into fixed-mobile converged services whilst also providing considerable benefits of in-building wireless coverage, capacity gain and shaping user behaviour. Crucially, this is more than just WCDMA.

Femtocells – For Mobile Operators

M bil t

Today Vodafone has 5,000 3G cell

Current Vodafone Coverage Map

p

Mobile operators can increase their capacity 500 fold using Femtocell t h l

sites in 3 sectorseach providing a capacity of 2Mbs technology

Customer provides cell site, installs

2Mbs= 30 Gbs

U i F t ll,

equipment and pays for electricity to run it and backhaul

Using Femtocells, Vodafone can have 2 million cell sites each with a capacity of 7 Mbs(1/4 f UK(1/4 of UK household with DSL already)=14,000 Gbs!

Femtocell Challenges

How does the Femtocell fit in the RAN?100Ks of Node-Bs attached to RNC / BSC / ASNCollapsed stackConnects to broadband (no backhaul timing available)

CostNeeds to have a BOM of $100-$200Needs to have a BOM of $100-$200Cheap baseband processing, RF and oscillator needed

Other technical challengesQoSHandoverProvisioningInterference mitigation

Industry is solving these issuesIndustry is solving these issuespicoChip will reflect these in our reference designs

WiMAX needs femtocells even more than 3G

WiMAX is at higher frequency: worse coverageWiMAX is predicated on high-speed data2.5GHz and 64QAM will not go well through wallsCoverage

Users are guaranteed coverage at their homeFemtocells can cover the surrounding area outside building
