CONCLUSION
3. INTRODUCTION
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.
4. 1G Technology
1G refers to the first-generation of
wireless telephone technology was
developed in 1970’s.
Analog signals is used
6. 2G Technology
Around 1980’s
Better quality & capacity - More people
could use their phones at the same
time
Digital Signals – consist of 0’s & 1’s
11. 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
14. 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
17. Enhanced 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
21. 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
