4G is the fourth generation of wireless technology that aims to provide faster broadband Internet access and support new multimedia applications. It succeeds 3G and earlier standards. Key features of 4G include support for high-speed multimedia services up to 100 Mbps for mobile users, global mobility between networks, and being fully Internet Protocol-based. The presentation provides an overview of 4G technology, its history and development from earlier generations, key characteristics and features of 4G networks and services, and how 4G compares to 3G.

4. WHAT IS 4G?
 A wireless access technology and is the successor of 3G.
 4G stands for the fourth generation of cellular wireless
standards.
 It is a successor to 3G and 2G families of standards. Speed
requirements for 4G service set the peak download speed at
100 Mbit/s for high mobility communication (such as from
trains and cars) and 1 Gbit/s for low mobility
communication.

5.  One of the terms used to describe 4G is MAGIC—
Mobile multimedia, Anytime anywhere, Global mobility
support, Integrated wireless solution, and Customized
personal service.
A 4G system is expected to provide a comprehensive
and secure all-IP based mobile broadband solution to
smart phones, laptop computer wireless modems and
other mobile devices.

6. WHAT'S NEW IN
4G?

7. HISTOR
Y
 This process began with the designs in the 1970s that have
become known as 1G. Based on analog technology and the
basic cellular structure of mobile communication.
 The 2G (second generation) systems designed in the 1980s
were still used mainly for voice applications but were based
on digital technology, including digital signal processing
techniques.
 During the 1990s, two organizations worked to define the
next, or 3G.
 The 3G system would have higher quality voice channels, as
well as broadband data capabilities, up to 2 Mbps.

8.  An interim step is being taken between 2G and 3G,
the 2.5G.
 A very important aspect of 2.5G is that the data
channels are optimized for packet data, which
introduces access to the Internet from mobile
devices, whether telephone, PDA
(personal digital assistant), or laptop.
 4G This new generation of wireless is intended to
complement and replace the 3G systems, perhaps in 5
to 10 years.

11. DRIVERS FOR
ADOPTING 4G11
 Opportunity for bundling with other services
 Reducing operational costs (OPEX)
 Introducing new applications and services
 Competition pressures
 Consolidating number of networks
 Multi-play devices available in the markets
 Multiple terminals
 Smart simplicity
 Outstanding performance

12. 4G
FEATURES12
 Support interactive multimedia, voice, video, wireless
internet and other broadband services.
 High speed, high capacity and low cost per bit.
 Global mobility, service portability, scalable mobile
networks.
 Seamless switching, variety of services based on Quality
of Service (QoS) requirements.
 Better scheduling and call admission control techniques.
 Ad hoc networks and multi-hop networks.

13. FEATURE OF 4G MOBILE
TECHNOLOGY
 Based on open wireless architecture (OWA)
 Congregate several RTTs (radio transmission
technologies) in one one device.
The device would enable detachable unused
modules.
Amalgamate home phone, office phone and
mobile
phone into one common Personal device.

14. FEATURES OF 4G
NETWORKS 4G networks are all-IP
(Internet Protocol) based
heterogeneous networks
 This will allow users to:
 Select any system at any time
and any where
 Use Multiple systems at the
same time (e.g. GPS and
WLANs and CDMA)
 A wide range of applications
using only one 4G integrated
terminal

15.  Support interactive multimedia services: teleconferencing,
wireless Internet, etc.
 Wider bandwidths, higher bit rates.
 Global mobility and service portability.
 Low cost.
 Scalability of mobile networks (>10 times the capacity of
3G).

17. This new generation of wireless is intended to complement and replace the 3G
systems, perhaps in 5 to 10 years. Accessing information anywhere, anytime,
with a seamless connection to a wide range of information and services, and
receiving a large volume of information, data, pictures, video, and so on, are
the keys of the 4G
infrastructures.

19. CONCLUSI
ON:
.
As the history of mobile communications shows, attempts have
been made to reduce a number of technologies to a single global
standard. Projected 4G systems offer this promise of a standard
that can be embraced worldwide through its key concept of
integration.
Future wireless networks will need to support diverse IP
multimedia applications to allow sharing of resources among
multiple users.
The fourth generation promises to fulfill the goal of PCC
(personal computing and communication)—a vision that
