INTRODUCTION

4G is the short term for fourth-generation wireless. It is still a researchlab standard , the stage of broadband mobile communications that willsupersede the third generation (3G). it is expected that end-to-end IPand high-quality streaming video will be among 4G's distinguishingfeatures.

A 4G system will be able to provide a comprehensive IP solutionwhere voice , data and streamed multimedia can be given to theusers on Anytime Anywhere basis and higher data rates than theprevious generations.

It will be a fully IP based integrated system capable of providing

between 100 Mbps to 1 Gbps in both indoor and outdoor withpremium quality and high security.

It is going to be launched in the year 2010.

OBJECTIVE

4G is being developed to accommodate the Quality of Service(QOS) and rate requirements set by forth coming applications like

1. MMS (Multimedia Messaging Service)

2. Wireless Broadband Service

3. Video Chat4. Mobile TV

5. Digital Video Broadcasting

6. High Network Capacity

7. Data Rate of 100 Mbps for mobile and 1 Gbps while stationary .8. Smooth handoff across heterogeneous network..

9. Seamless Connectivity and Global Roaming across multiplenetworks

ITU designed 4G in 2002 with the officialname 3G Long-Term Evolutions or 3.9G

Will allow users to download a full-lengthfeature film within five minutes

Will also be able to stream high-definition

television and radio to hand-held devices The basic difference between 3G and 4G

is in data transfer and signal quality


5/18

The highest download and upload speed in 3Gare 14 Mbps and 5.8 Mbps respectively

In 4G the download speed is up to 100 Mbps for

moving users and 1 Gbps for stationary users 4G is adoption of packet switching instead of

circuit switching in voice and video calls

With packet switching, resources are only usedwhen there is information to be sent across

4G uses spiral multiplexing


6/18

There are three primary technologies that

support 4G WiMax, LTE, and UMB

The main doubt is whether to implement WiMaxor LTE

The advantages of LTE are:

(i) Faster speed with 100 Mbps for download and

50 Mbps for upload

(ii) It makes CDMA and GSM database moot

(iii) It offers both FDD and TDD duplexing

TECHNOLOGY USED IN 4G

Time-line from 1G to 4G and beyond:

The first generation, 1G wireless mobile communication systems, wasintroduced in the early 1980s. 1G wireless was analogandsupportedthe first generation of analog cell phones with the speeds up to 2.4kbps.

The second generation, 2G system, fielded in the late 1980s.It wasplanned mainly for voice transmission with digital signal and the speedsup to 64kbps.

The third generation, 3G wireless system also called UMTS (Universal MobileTelecommunications Standard). , was developed in the late 1990s .3G is notonly provided the transmission speeds from 125kbps to 2Mbps, but alsoincluded many services, such as global roaming, superior voice and videoquality.

The fourth generation (4G) is a conceptual framework just raised in2002. The speeds of4G can theoretically be promised up to 1Gbps. Thebeyond will be 5G with incredible transmission speed with no limitationfor access and zone size

GENERATIONS TIMELINE :


9/18

Has already begun the process of introducing4G

India is among the latecomers in 3G

It is felt that by the time the implement 3G fully,

4G technologies such as LTE will be availablecommercially

It has taken three years for the government todecide on 3G-spectrum auction policy

4G could face the same delay unless Indiawants to catch up with the rest of the world

Telecom Companies Devloping 4G

1. NTT DoCoMo (JAPAN)

2. DIGIWEB (IRELAND)

3. SPRINT (CHICAGO)4. VERIZON WIRELESS

5. VODAFONE GROUP

6. AMERICAN WIRELESS PROVIDERCLEARWIRE ETC..

APPLIICATIONS

The applications of 4G are called KILLERAPPLICATIONs as it is going to bring to

revolution in the internet world.

-- High Speed Data Rate due to which a moviecan be downloaded in 2 to 3 minutes.

-- More Security

-- Video Conferencing-- Higher Bandwidth

-- Global Roaming


12/18

High Speed: Data Rate of 100 Mbps for mobile and1 Gbps while stationary

Global Standard:-4G will be a global standard that

provides global mobility and service portability so thatservice provider will no longer be limited by single-system.

Low cost:access technologies, services andapplications can unlimitedly be run through wirelessbackbone over wire-line backbone using IP address.

FUTURE OF 4G:5G (completed WWWW:World Wide Wireless Web):

The idea of WWWW, World Wide Wireless Web, isstarted from 4G technologies. The followingevolution will based on 4Gand completed its ideato form a REAL wireless world. Thus, 5G shouldmake an important differenceand add more

services and benefit to the world over 4G; 5Gshould be a more intelligent technology thatinterconnects the entire world without limits


16/18

CONCLUSION

As the history of mobile communicationsshows, attempts have been made to reduce anumber of technologies to a single global

standard. 4G seems to be a very promising generation of

wireless communication that will change thepeoples life in the wireless world.

4G is expected to be launched by 2010 and the

world is looking forward for the most intelligenttechnology that would connect the entire globe.
