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.

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.

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

Traditional & Next Generation Features of LTE/VOLTE

Transmission Scheme

Spectrum Flexibility

Error Correction

System Architecture

MIMO

Enhanced MIMO Techniques

Relay Nodes

Carrier Aggregation

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.

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.

4G Services & Applications

Localized/Personalized Information.

Organizational Services

Communication services and applications

Entertainment services

Mobile commerce(M-Commerce)

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.

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.

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.

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.

Basic Applications of 4G

Virtual Presence.

Virtual Navigation.

Better usage of multimedia applications.

Crisis management application.

Security

Tele geoprocessing, telemedicine

MAGIC

Mobile Multimedia

Anytime Anywhere

Global Mobility Support

Integrated Wireless Solution

Customized Personal Services

Also Known as Mobile Broadband Everywhere.

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.

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.

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.

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.

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.

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.
