3. Introduction
4G
An abbreviation for Fourth-Generation
Provide wireless network access at a higher speed
approx. 100 mbps
Quick to surf the web on your mobile, tablets and
laptops
It uses different frequencies for transmit data
More faster because of Orthogonal Frequency-
Division Multiplexing (OFDM).

4. LTE
• Stands for Long Term Evolution
• It is a 4G wireless broadband technology by
the Third Generation Partnership Project
(3GPP), an industry trade group.
• The goal of LTE was to increase the capacity
and speed of wireless data networks using
new DSP (digital signal processing) techniques.

5. 4G-LTE
• An accurate name for 4G LTE technology is 4G
candidate LTE.
• To use this technology we get the actual speed
of 4G network and become an accepted 4G
standard.
• Achieving higher speed in two ways-:
• uses existing bandwidth more efficiently than
older technologies
• they transmit and receive via multiple inputs
and outputs.

6. Objectives
• High network capacity.
• A nominal data rate of 100 Mbps while the client
physically moves at high speeds relative to the station,
and 1 Gbps while client and station are in relatively
fixed positions,
• A data rate of at least 100 Mbps between any two
points in the world.
• Seamless connectivity and global roaming across
multiple networks,
• High quality of service for next generation multimedia
support (real time audio, high speed data, HDTV video
content, mobile TV, etc)

7. History
• The first generation of mobile communications started
with the Advanced Mobile Phone Systems (AMPS),
which was an analogue system. AMPS can be thought
of as 1G.
• From there, we progressed to GSM and CDMA-one
(pretty much regarded as 2G) and then to UMTS and
EV-DO, which are 3G technologies.
• The latest technologies that are regarded as candidates
for 4G are LTE (from the 3GPP group) and 802.16m
(from the IEEE).
• LTE progresses through versions known as releases.
The latest release that qualifies as being 4G is release
10, often called LTE-Advanced.

8. Uses
• Large file transfer
• Rapid workplace set-up
• Rich machine to machine and remote
monitoring applications
• Videoconferencing, tele-presence and rich
media collaboration
• Remote access to business applications

10. Applications
• E-readers,
• Mobile IPTV,
• Mobile marketing and geo-targeted
advertising,
• Location-based mobile applications
embedded in social networking

11. Advantages
• It transmits and receives data very quickly.
• It provides considerably higher data
bandwidth, which means more data capacity
per user.
• Makes quick connections when changing cells,
and it doesn’t drop connections.
• It is compatible with previous generations of
mobile network technology as well future
versions.

• DL and UL schemes
• Protocol Architecture
• Spectrum Flexibility
• Cell size support
• Network architecture

16. Conclusion
• LTE-A helps in integrating the existing
networks, new networks, services and
terminals to suit the escalating user demands
• LTE-Advanced will be standardized in the 3GPP
specification Release 10 (LTE-A) and will be
designed to meet the 4G requirements as
defined by ITU
