Femtocell Concept
Confidential
�Indoor cellular coverage
�Can “talk” with any handset device
�Low cost backhauling
A Femtocell Definition
� A small cellular base station, designed for use in residential.
� Connects to the service provider’s network via broadband.
� Support 2 to 5 mobile.
� Allows service providers to extend service coverage indoors.
Confidential
� Allows service providers to extend service coverage indoors.
� Incorporates the functionality of a typical base station but extends it to allow a simpler, self contained deployment.
� The concept is applicable to all wireless standards, including UMTS, GSM, CDMA-2000, TD-SCDMA and WiMAX solutions.
UMTS Macro NW Architecture
Confidential
UMTS Femtocells Architecture
�Iub over IP Architecture
Confidential
�Scalability ProblemRNC can’t handle 1000s of NodeBs
UMTS Femtocells Architecture
�Iu over IP Architecture
Confidential
�Requires RNC implementation per femtocell
UMTS Femtocells Architecture
�SIP/IMS Architecture
Confidential
�Requires changes at the existing CNs
UMTS Femtocells Architecture
Confidential
�De-facto architecture is the Iu over IP
Femtocells Challenges
�Femtocell Cost
�Network Architecture Harmonization
�RF Interference

�RF Interference
�Remote Device Management
�Potential Consumer Concerns
Femtocells Cost
�Today femtocell price is ~$250
�Femtocell price must be less than $100 in order to have a high volume market
�Digital baseband and RF ICs must be
Confidential
�Digital baseband and RF ICs must be highly integrated
Network Arc Harmonization
Confidential
RF Interference
�Need to investigate the interference scaling effect of large deployments of femtocells on the same/adjacent carrier in a range of different networks
Confidential
Potential Consumer Concerns
A basestation at my home???
�Femtocell transmits less than DECT or WiFi
�Handset transmits less power near femtocell
Confidential
�Handset transmits less power near femtocell
�UMTS femtocell max transmit power is 10-17dBm (3G handset max transmit power is 21dBm)
