The Femto Forum

• Large number of membersEcosystem Development

Aims Implications

• Promoting & enabling femtocells• Not-for-profit, founded in 2007• Independent, Inclusive, International

• Large number of members• Geographical and technological spreadEcosystem Development

• Spreading awareness• Increasing informed coverageMarket Education

• Not a standards-setting body

• Building voluntary consensus• Close interactions with standards bodies

Driving open standards

What are femtocells?• Low-power access points…

…using mature mobile technology

…in licensed spectrum

…generating coverage and capacity

…over internet-grade backhaul

…at low prices …at low prices

…with full operator management

…self-organising, self-managing

Generic Femto Network Architecture

Already 4 commercial deployements

in various regions

• Femtocell economies of scale can deliver cost-effective deployments in offices and in high-traffic or low coverage locations

• Femtos in the enterprise and metrozone

• Dedicated features:

• Femto-femto handover, closed subscriber group

• Local break out, presence detection

‘Greater’ Femtocells: Not only for the home!

• Local break out, presence detection

Macrocells – wide area coverage and mobility

Self Organised Network• Femto is plug and play device

• No need for planification and network optimisation

• Femto use specific algorithm to configure its frequency, output power, scrambling code and other parameters to minimize interference with external world

� femto starts to transmit� femto defines its best radio parameters

� femto scans 2G and 3G surrounding networks

M2M module

mobile

Presence, location check

• Each femto broadcast a specific Location Area

• Device entering the area will register automatically

�Automatic location trigger

Paging processPresence notif: IMSI1, IMS2

Presence request

�Automatic location trigger

• Possibility to locate on a per cell basis

regulatory

• Main concern: spectrum is exclusive to mobile operators

• Mobile operators seems not ready to share this asset

• Radio architecture is becoming more flexible with • Radio architecture is becoming more flexible with possibility to cover multiple bands or even large spectrum

• Femto ecosystem could be refined to close frequency to use it in unlicensed or reserved spectrum

conclusion

• Femto is becoming a mature technology

• Mobile operator are largely investing in this technology

• Femto are ready to be used in factory
