3. INTRODUCTION
3GPP is a collaboration of several groups which is responsible for
developing LTE referred to as 4th generation of access technology.
Long Term Evolution (LTE) is the fourth generation of radio access
technology, also referred to as 4G.
LTE is IP based technology where voice and data services are delivered
in packets as compared to the Legacy networks.
3GPP, which has developed several mobile radio standards over the
years and were widely used.
4. HISTORY
4G is the latest and fastest generation of mobile phone communications.
4G is based on same 3G Technology with improvements named as LTE.
LTE was first used in Sweden in 2009.
4G speed ranges from 100MB/s to 1GB/s. LTE stands for Long Term
Evolution.
4G is the next generation mobile broadband technology.
It promises data transfer rates of 100 Mbps and is based on UMTS 3G
technology.
It is optimized for All-IP traffic.
5. Need for 5G
5G innovation offer high determination for insane mobile phone
client and bi-directional extensive data transfer capacity molding.
5G innovation offer transporter class passage with unparalleled
consistency.
Battery Consumption Alleviation
Improved scope range and higher information rate accessibility at
cell edge.
Multiple simultaneous ways for information transmission also, hand
over.
5G gives backing to intelligent sight and sound, voice, video,
Internet, and other broadband administrations
6. Traditional & Next Generation Features of LTE/VOLTE
Transmission Scheme
Spectrum Flexibility
Error Correction
System Architecture
MIMO
Enhanced MIMO Techniques
Relay Nodes
Carrier Aggregation
7. Spectrum Flexibility
Another important aspect of LTE is that it provides spectrum flexibility.
Radio spectrum for LTE mobile communication comes in different sizes
depending on the regulatory aspects for each geographical location.
LTE provides asymmetric spectrum utilization by using different uplink and
downlink bandwidths.
LTE can also assign different bandwidths to operate in spectrums of
different bandwidths to enable migration to LTE from other radio access
technologies.
Cell sizes can range from 1-100km.
8. OFDM Advantages
Adaptable to severe channel conditions without complex equalization.
High spectral efficiency.
Efficient implementation using FFT.
Low sensitivity to time synchronization errors.
Facilitates Single Frequency Networks(SFNs), i.e. transmitter macrodiversity.
9. 4G Services & Applications
Localized/Personalized Information.
Organizational Services
Communication services and applications
Entertainment services
Mobile commerce(M-Commerce)
10. Technologies used in 4G
Smart Antennas for Multiple-input and
multiple output(MIMO).
IPv6
VoIP (Voice Over Internet Protocol)
OFDM
Software Defined Radio (SDR) system.
11. Advantages of 4G
Affordable Communication Services.
High speed, high capacity and low cost per bit.
Support for interactive multimedia, voice, streaming video, Internet and
other broadband services.
Better spectral efficiency.
Seamless network of multiple protocol and air interfaces.
Higher bandwidth.
Better response time. 10 times better than 3G.
Works at 2.6 GHz frequency.
12. Disadvantages of 4G
New technology which makes it more expensive than 3G.
Battery usage is more.
Hard to implement.
Need complicated hardware.
The equipment required to implement a next generation network is still
very expensive.
Carriers and providers have to plan carefully that expenses are kept
realistic.
13. Why 4G over 3G?
4G(lte) is quicker than 3G.
4G plus network uses the 1800 &
2300 MHz frequency bands.
3G plus network uses the 900 &
2100 MHz frequency bands.
4G holds:
less buffering,
better audio quality,
improved gaming experience
Streaming services with reduced
lag.
15. MAGIC
Mobile Multimedia
Anytime Anywhere
Global Mobility Support
Integrated Wireless Solution
Customized Personal Services
Also Known as Mobile Broadband Everywhere.
16. Benefits of 5G
High speed, high capacity.
5G technology providing large broadcasting of data in Gbps.
Faster data transmissions that of the previous generations.
Large phone memory, dialing speed, clarity in audio/video.
Support interactive multimedia, voice, streaming video, Internet and other.
5G is more effective and more attractive.
17. CHALLENGES
No large user community for advanced mobile data applications.
Comparatively higher cost to use and deploy infrastructure.
Not possible to offer full internet experience due to limited speed and
bandwidth.
Improved User interfaces.
Advanced speech recognition and synthesis.
18. SWOT ANALYSIS
STRENGTHS
Strong position of telecom vendors expected in market.
Advantage for personalized multimedia communication tools.
WEAKNESSES
Growing divergence between telecom vendors an operators.
Comparatively higher cost to use and deploy infrastructure.
19. CONTD…..
Opportunities
Worldwide economy cover stimulates consumption and consumer
confidence.
Desirable higher data capacity rates the growth opportunity is very bright
and hopeful.
Threats
Since 3G mobile is still in the market, it squeezes the market competition
in mobile industry.
20. Future trend of LTE(5G)
5G technology refer to short name of fifth generation.
Complete wireless communication with no limitations.
It is highly supportable to WWWW( Wireless World Wide Web).
5G envisions to design a wireless world, that is free from obstacles of the
earlier generations.
5G requires an integration of networks.
21. CONCLUSION
Evolution to LTE-Advance from LTE was done to meet the requirements set
by IMT-Advance.
LTE has provided a good foundation for an evolution in mobile radio
communications industry.
Attempt has been made to reduce a no of technologies to a single global
standard.
Mobile Intelligent Internet and multimedia applications.
4G is best as compared with its predecessors.
