This document summarizes the key technologies and evolution from 1G to 5G mobile networks. It discusses the major standards and technologies used in each generation including TDMA, CDMA, HSDPA, LTE, WiMAX and more. It then covers the expected architecture and capabilities of 5G networks, including support for ultra-high bandwidth, low latency connections; integration of different network standards; and a converged "super core" network infrastructure. The conclusion reiterates that 5G will provide convergence of networks, flexible services, and change people's lives through wireless innovation.

6. 5G is a packet switched wireless system with wide area
coverage(wwww) or world wide wireless web.
freedom of movement from one technology to another.
The intelligent Internet phone concept where the mobile phone
can choose the best connections by selected constraints and
dynamically change them during a single end-to-end connection.
The 5G terminals will have software defined radios and
modulation scheme as well as new error-control schemes can be
downloaded from the Internet on the run.
user-centric concept instead of operator-centric as in 3G or
service-centric concept as seen for 4G.

7. 
5G being developed to accommodate QoS rate
requirements set by further development of existing 4G
applications.

Flexible channel bandwidth between 5 and 20MHz,
optionally up to 40MHz.

Data rate of atleast 1Gb/s between any two points in the
world.

Increase system spectral efficiency of up to 3bit/s/Hz/cell
in the downlink and 2.25bit/s/Hz/cell for indoor usage.

8. Architecture Of 5G
IT DEFIES MOORE’S LAW
Moore’s law "the number of transistors that can be fit onto a
square inch of silicon doubles every 12 months." Moore's law
describes a longterm trend in the history of computing
hardware but it also prove true for wireless technologies. From
1G (1st Generation) to 4G (4th Generation).
5G wireless architecture will be generation will defy the Moore
law and it will be phase of integration of network technologies,
rather expansion or evaluation of new wireless standard.

10. Architecture Of 5G(cont..)
Ubiquitous Computing
Ability to access all the applications we
want from any platform, anywhere, any
time.
Human life will be surrounded by
intelligent sensors, which will bring radical
change to human life’s daily approaches of
doing things

11. Architecture Of 5G(cont..)
Aggregator
All network operators (GSM, CDMA,
Wimax, and Wireline) can be connected to
one Super core with massive capacity. This
is realization of single network
infrastructure.
The concept of aggregator will eliminate
all
interconnecting
charges
and
complexities.
It will also reduce number of network
entities in end to end connection, thus
reducing latency considerably

12. Architecture Of 5G(cont..)
Flat IP network
It is the key concept to make 5G
acceptable for all kind of technologies.
Flat IP architecture provides a way to
identify devices using symbolic names,
unlike the hierarchical architecture such as
that used in "normal“ IP addresses.
This is of more interest to mobile
broadband network operators.

13. Architecture Of 5G(cont..)
The 5G Nancore
It is a convergence of below mention
technologies. These technologies have
their own impact on exiting wireless
network which makes them in to 5G.
Nanotechnology.
Cloud Computing.
All IP Platform.

14. The system will consists of a user
terminal and a number of independent,
autonomous radio access technologies
(RAT).Each of the RAT is seen as the IP
link to the outside Internet world.
Different radio interface for each RAT in
the mobile terminal.
Example, to access four different RATs,
we need to have four different access specific interfaces in the mobile
terminal, and to have all of them active
at the same time, with aim to have this
architecture to be functional

Performance Measurement
Execution Functional Entity (PMEFE)
Performance Measurement
Processing Functional Entity (PMPFE)
Performance Measurement
Reporting Functional Entity (PMRFE)

18. 
High capacity, and low cost per bit.

Support interactive multimedia, voice, streaming video, Internet,
and other broadband services ,more effective and more
attreactive ,Bi directional ,accurate traffic statistics.

Global access, service portability, and scalable mobile services.

The high quality services to avoid error.

5G technology will provide large broadcasting of data in
Gigabits.

Remote management better and fast solution.

19. Integration of various standards: Each engineering practice has their own
standard . To integrate thesevarious standards, requires systematic and time
consuming approach.
Common Platform: There is no common architecture for interconnecting
various engineering practices.
High redundancy: Under Super core concept, all network operators will be
moving to single core infrastructure, high redundancy and security among core
network entities is required. A failure of single node will impact huge number
of subscribers across various network operators
Transparency among network operators, regarding Subscriber data, churn
management, etc. Government regulatory framework for Super core.

20. Conclusion
Migration to 5G networks ensures convergence of networks,
technologies, applications and services.
5G can serve as a flexible platform.
Wireless carriers have an opportunity to shorten Investment
return, improve operating efficiency and increase revenues.
5G - a promising Generation of wireless communication that
will change people’s lives.
