4G is a collection of technologies providing fully packet-switched networks optimized for data transmission. 4G networks are projected to provide speeds up to 100Mbps for mobile use and 1Gbps when stationary. The document traces the development of wireless technologies from 1G analog networks to 2G digital networks to 3G which enabled multimedia. 4G aims to provide even faster speeds, lower costs, support for multiple wireless standards simultaneously, and new capabilities like enhanced mobile gaming and broadband access in remote areas not served by infrastructure. Research into 5G technologies is already underway as the next generation of wireless beyond 4G.

2. 4G Definition
 4G is not one defined technology or
standard, but rather a collection of
technologies at creating fully packet-
switched networks optimized for data.
 4G Networks are projected to provide
speed of 100Mbps while moving and
1Gbps while stationary.

3. 1G Technology
 1G refers to the first-generation of
wireless telephone technology was
developed in 1970’s.
 Analog signals is used

4. 1G mobile phones

5. 2G Technology
 Around 1980’s
 Better quality & capacity - More people
could use there phones at the same
time
 Digital Signals – consist of 0’s & 1’s

6. 2G Technology

7. 2G mobile phones

8. 3G Technology
 Large capacity and broadband capabilities
 Allows the transmission of 384kbps for
mobile systems and up to 2Mbps

9. 3G support Mobile phone

10. Reasons for New Research
 Even though 3G has successfully been
introduced to mobile users, there are some
issues that are debated by 3G providers and
users.
 High input fees for the 3G service licenses
 Great differences in the licensing terms
 3G phones are expensive

11. Fourth Generation

13. 4g mobile phone

14. WHY 4G?
 1G Analogy Communication
 2G Digital Communication
 3G Multimedia
 4G More Services

15. What is 4G?
 Fourth Generation Technology
 Faster and more reliable
 100 Mb/s
 Lower cost than previous generations
 Multi-standard wireless system
 Bluetooth, Wired, Wireless
 Ad Hoc Networking
 IPv6 Core
o Primary technologies that support 4G
Eg::WiMax,LTE,UMB

16. Ad Hoc Networks
 Spontaneous self
organization of networks
of devices
 4G will create hybrid
wireless networks using
Ad Hoc networks
 Form of mesh
networking–Very reliable

18. Enhance Mobile Gaming
 Experience enhance wireless capabilities
that deliver mobile gaming interaction
with less than five seconds
 Play online multi player games while
traveling at high speeds or sitting outside

19. Broadband access in Remote
location
 4G will provide a wireless alternative
for broadband access
 It will provide first opportunity for
broadband access in remote locations
without an infrastructure to support
cable

20. CONCLUSION:
 4G is not a final solution in mobile
communication…..The research is
going on…
 Now a days 5G (5th generation
mobile networks or 5th generation
wireless systems) is a name used in
some research papers and projects
 We can expect ‘NEW’ within some
months
