Mobile cellular and 3G networks normally often suffer from poor penetration and reception in certain areas, like indoors. This decreases the quality of voice and video communication and slows down high-speed services. A femtocell is a small device that is used to improve wireless coverage over a small area, mostly indoor. It is a small cellular base station, also called a wireless access point that connects to a broadband Internet connection and broadcasts it into radio waves in its area of coverage. As a result, mobile handsets can handle phone calls through the femtocell, via the broadband Internet connection.

2. "CAN YOU HEAR ME NOW????"

3. • This is often the case of in homes and buildings where
coverage decreases considerably as soon as you go
indoors.
• People are ditching their landlines in favor of mobile
phones.
• It has become necessary to work on new technology that
will facilitate calling coverage both indoor and outdoor.
INTRODUCTION

4. • Femtocell Technology could be the answer.
• In addition to facilitating better indoor call coverage , this
emerging technology reduces the drain that advanced
mobile services.

5. • A small device which is installed in home or office in order
to offer better support to mobile phones.
• These base stations can accommodate up to five cell
phones.
• Enhance the cell phone signal that you receive indoors.
• Now many operators are providing femtocell service.

6. PROBLEMS
• Mobile cellular and 3G networks normally often suffer
from poor penetration and reception in certain areas ,like
indoors.
• This decreases the quality of voice and video
communication.
• It slows down high speed services.

7. WHY IS FEMTOCELL IMPORTANT?
Femtocells very important for the following reasons:
 It can provide indoor coverage for places where macrocells
cannot .
 It can offload traffic from the macrocell layer and improve
macrocell capacity .
 Addition of a femtocell layer will significantly improve the total
network capacity by reusing radio spectrum indoors .
 There is a growing demand for higher and higher data rates.

8.  Femtocells can provide significant power saving to UEs .
The use of femtocells ‘greener’ than macrocells .
Femtocell provides an ideal solution for FMC .
 Femtocell plays an important role in mobile broadband
and all over communications.

12. HANDOVER OPERATION
 Handover in mobile phone systems:
 A mobile phone switches between different call sites during a phone call.
 Femtocell Handover:
Femtocell do not implement soft handover
 All calls are switching instantly from femtocell & external outdoor cellular
network.
 This is known as hard Handover.
 The 2G & 3G systems co-exist, it automatically select 3G where good
reception.

13.  Optimizing Handover into a Femtocell:
 There are 3 approaches
 Adding femtocells to the neighbour lists.
 Adding some smarts into mobile phone.
 Making the femtocell as clever as possible.

14. TYPES OF FEMTOCELL
DOMESTIC
ENTERPRISE
METRO-FEMTO

15. ADVANTAGES
 Cellular Users
 Simple deployment
Increased user throughput
 Lower transmit power
Prolong handset battery life
 Improved indoor coverage
New applications
 Security

16. Network Providers
 Enhanced services
 Increased revenue
Offload data traffic
 Increased area spectral efficiency
Improved customer satisfaction

17. DISADVANTAGES
 Difficult to install
 Requires broadband connection
 It does not provide good coverage in outdoors

18. SECURITY
Femtocell security risks
User privacy
Denial of service and general service availability- the link between
the femtocell and the cellular core network is across the Internet
and it is IP based.
 Fraud and service theft.

19. Femtocell security measures .
Use of Ipsec .
Femtocell Secure Authentication .
 Wireless link security .
 EAP, Extensible Authentication Protocol

20. QUALITY OF SERVICE
 In shared-bandwidth approaches, which are the
majority of designs currently being developed, the
effect on Quality of Service may be an issue.

22. SOME FEMTOCELLS

23. CONCLUSION
• Femtocells are on a road to nowhere .
• Unsatisfactory coverage and the increasing number of high-data-
rate application are two driving forces for femtocell development .
• Femtocells have the potential to provide high quality network
access to indoor users at low cost.
• Improve coverage .
• Provide huge capacity gain.
