1. Technology

2. 
 femtocell is a small, low-power cellular base station,
typically designed for use in a home or small
business
 It connects to the service provider’s network via
broadband (such as DSL or cable)
 A femtocell allows service providers to extend
service coverage indoors or at the cell edge,
especially where access would otherwise be limited
or unavailable.
INTRODUCTION

3. 
FEMTOCELL

4. 
 Although much attention is focused on WCDMA,
the concept is applicable to all standards, including
GSM, CDMA2000, TD-SCDMA, WiMAX and LTE
solutions.
 Femtocells are an alternative way to deliver the
benefits of fixed-mobile convergence (FMC)
 Many operators have launched femtocell service,
including Vodafone, SFR, AT&T, Sprint Nextel,
Verizon, Zain, Mobile TeleSystems, and Orange.
STANDARDS

5. 
 Femtocells are sold by a mobile network operator
(MNO) to its residential or enterprise customers
 it is plug and play, there is no specific installation or
technical knowledge required—anyone can install a
femtocell at home.
 Femtocells require specific hardware, so existing
WiFi or DSL routers cannot be upgraded to a
femtocell.
OPERATING MODES

6. 
PROCESS

7. 
 The standards bodies have published formal
specifications for Femtocells for the most popular
technologies, namely WCDMA, CDMA2000, LTE
and WiMAX.
1. femtocell should act as its own access points.
2. authentication of encrypted IP data.
3. allows software updates and diagnostic checks
to be administered.
ARCHITECTURES

8. 
 The key interface in these architectures is that
between the Femtocells access points and the
Femtocells gateway.
 common WCDMA Femtocells, this is defined as the
Iuh interface
 In luh architectures Femtocell gateway acts as a the
intermediate between the femtocell and core
network.
 It performs the translation of data to set the femtocell
as the radio network controller to the mobile
switching centres(MSC)
 In March 2010, the Femto Forum and ETSI
conducted the first Plug fest to promote
interoperability of the Iuh standard

9. 
SERVICE

10. 
There is a security tunnel which provides
data transmission from the home network to
the security gateway.
Link from the home network to the core
network through is insecure. To make it
secure the femtocell implements IPSEC.
SECURITY

11. 
 Secure storage and execution
1. hosting party module
2. trusted environment
 Mutual authentication
1. device mutual authentication
2. hosting party mutual authentication
 Location verification
the operator needs to verify the home network
for prevent illegal access.
SECURITY FUNCTIONS

12. 
EXAMPLE

13. 
MODELS

14. 
 compensating poor cellular coverage inside the
homes
 lower call charges while the caller calling from home
 maximum functionality.
 Femtocell can provide 3G services.
 High bandwidth.
 Larger data transmission.
ADVANTAGES

15. 
 Limited connection
 Some internet data plans today, charge on the basis
of bandwidth used.
 neighbouring subscribers may or may not be
allowed to connect to them
 Trouble shooting is difficult.
 Only 5 users can be allowed to use.
DISADVANTAGE

16. 
Femtocell is the latest emerging technology
that can solve the signal problems in the
cellular network. It can be used to provide
high speed internet connectivity. It can also
be used to implement the Wi-Fi connection
for internet. The wireless internet connection
problems can be solved by this technology.
