5. What is 4G?
It is 4th generation wireless technology.
It will provide a comprehensive IP solution where
voice, data and multimedia can be given to user on “any
time , anywhere” basis.
It includes several types of broadband wireless
communication system access including cellular
telephone system.
It will provide seamless mobility and internet access at a
rate of 100 Mbps.
6. Why 4G is required?
Due to substantial growth in overall number of
subscribers.
Due to massive demand of new services like data , audio
, image or video .
7. Features of 4G TECHNOLOGY
High performance
Easy roaming
Fully converged services
Low cost
More user friendly devices
Enhanced GPS Services
Scalability
Crisis Management application
8. Technology used in 4G
OFDM: orthogonal frequency division multiplexing
UWB: ultra wide band
Smart antennas
IPv6:internet protocol version6
11. Application
In traffic control.
Multimedia – video services
Telemedicine.
Crisis Management
Virtual Navigation
12. Limitations
Cost is another factor that could hamper the progress of
4G technology . The equipment required to implement
the next-generation network are still very expensive.
A Key challenge facing deployment of 4G technologies
is how to make the network architectures compatible
with each other. This was one of the unmet goals of 3G.
As regards the operating area, rural areas and many
buildings in metropolitan areas are not being served well
by existing wireless networks.
13. Conclusion
4G systems offer to reduce a number of technologies to
a single global standard.
Future networks need to support diverse IP multimedia
applications to allow sharing of resources among
multiple users.
4G fulfilled the goal of PCC ( personal computing and
communication ).
