MOBILE SYSTEM GENERATIONS

.

First Generation (1G) mobile systems were designed to offer

single service, i.e., speech.

Second Generation (2G) mobile systems were also designed

primarily to offerspeech with a limitedcapability to offerdata at low rates.

Third Generation (3G) mobile systems are expected to offer

high-quality multi-media services andoperate in different environments

WHAT IS FOURTH GENERATION (4G)MOBILE SYSTEMS?

Fourth generation mobile communications systems that arecharacterized by high-speed data rates at 20 to 100 Mbps,

suitable for high-resolution movies and television, multimedia

Initial deployments are anticipated in 2010.

Convergence of High Speed Internet&

Mobility

The Wireless Industry has grown at enormous pace over

the past decade.

More than a billion subscribers to cellular services are enjoying

the benefits of staying connected while on the move.

with the growth in Internet, a wide range of services are

accessed by users through a wired infrastructure.

The introduction of mobile Internet brought about by

the convergence of Mobile & Internet technologies is

the future objective.

4G CONCEPT

The user has freedom and flexibility

to select any desired service with

reasonable QoS and affordable price,

anytime, anywhere.

Benefits for

USERS

Select network depending on service requirements and cost.

Connect to any network Worldwide roaming. Access to new services

OPERATORS

Respond to variations in traffic demand (Incorporate service enhancements and improvements. Correction of software bugs and upgrade

PERSONAL MOBILITY

In addition to terminal mobility, personal mobility is a

concern in mobility management.

Personal mobility concentrates on the movement of users

instead of users terminals, and involves the provision of personal communications and personalized operating

environments.

Once the callers agent identifies users location, the

callers agent can directly communicate with his agent.

MULTIMEDIA VIDEO SERVICES

4G wireless systems are expected to deliver efficientmultimedia services at very high data rates.

Basically two types of video services:

bursting

streaming.

Streaming is performed when a user requires real-time

video services,. Bursting is basically file downloading using a buffer and

this is done at the highest data rate taking advantage

the whole available bandwidth.

APPLICATIONS

TELEMEDICINE & EDUCATION-

4G will support remote health monitoring of patient

for people who are interested in life long education ,

4G provides the good opportunity.

CRISES MAAGEMENT-

Natural disasters can cause breakdown in communication

system in todays world it might take 7 weeks to restore the

system but in 4G it is expected to restore in few hours.

CONCLUSION

As the history of mobile communications shows

attempts have been made to reduce a number of

technologies to a single global standard.

4G seems to be a very promising generation ofwireless communication that will change the peoples

life in the wireless world.

4G is expected to be launched by 2010 and the world

is looking forward for the most intelligent technology

that would connect the entire globe.
