3. What is 4 G ?

4. • 4 G refers shortly to the fourth generation of
mobile telecommunication which was started in
the late 2000’s.
• Capable of providing 100Mbps-1Gbps.
• One of the basic word to describe 4 G is MAGIC.
*Mobile Multimedia
*Anytime Anywhere
*Global Mobility Support
*Integrated Wireless Solution
*Customized Personal Services

5. About 4 G

6. • 4 G also has a name called LTE or Long Term
Evolution.
• It is a registered trademark owned by ETSI
(European Telecommunications Standard
Institutes)
• The main goal was to increase the speed and
capacity of wireless communication through
DSP (Digital Signal Processing)
• It has no restrictions over wireless and weird
network operators

7. 4 G or LTE has further two different
systems of working
*LTE-TDD(Long Term Evolution-Time
Duplex Division)
*LTE-FDD(Long Term Evolution-
Frequency
Duplex Division)
• The most common system used in our
network operating is LTE-TDD.

8. History of 4 G

9. • 4 G or LTE was first proposed by NTT DoCoMo
of Japan in 2004.
• In 2004 the LTE developed had only voice calls
and it was denoted by VoLTE.
• In 2005-2008 developed Data Services and it
was under process to the network operators
in 2009 .
• After 2010 there was development of
Simultaneous Voice and LTE(SVLTE) i.e use of
voice calls and data services at a time.

10. Advantages of 4 G
over other
generation mobile
communications

11. • Affordable communication services.
• High speed, high capacity and low cost per bit.
• Support for interactive multimedia , voice ,
streaming video , internet and other
broadband services.
• Global access , service portability , scalable
mobile services and variety of quality of
service provided.
• Better spectral efficiency.
• Seamless network of multiple protocol and air
interfaces.

14. Disadvantages

15. • Battery use is more.
• Hard to implement.
• Need complicated hardware.
• The equipment required to implement the
next generation network is still very
expensive.
• Carriers and providers have to plan carefully
to make sure that expenses are kept realistic.

16. Applications

17. • Better usage of multimedia Applications.
• Virtual Presence.
• Virtual Navigation.
• Tele-geo processing.
• In Normal life
i)Traffic Control
ii)Mobile Phones
iii)Sensor on public vehicles.
