3G is the third generation of wireless

technologies. It comes with enhancements over

previous wireless technologies, like high-speedtransmission, advanced multimedia access and

global roaming. 3G is mostly used with mobile

phones and handsets as a means to connect the

phone to the Internet or other IP networks in

order to make voice and video calls, to download

and upload data and to surf the net.



This first generation (1G) analog system for mobile

communications saw two key improvements during

the 1970s: the invention of the microprocessor and

the digitization of the control link between themobile phone and the cell site.

Second generation (2G) digital cellular systems

were first developed at the end of the 1980s. These

systems digitized not only the control link but alsothe voice signal. The new system provided better

quality and higher capacity at lower cost to

consumers.



Third generation (3G) systems promise faster

communications services, including voice, fax andInternet, anytime and anywhere with seamless

global roaming. ITU¶s IMT-2000 global standard

for 3G has opened the way to enabling innovative

applications and services (e.g. multimediaentertainment, infotainment and location-based

services, among others). The first 3G network was

deployed in Japan in 2001. 2.5G networks, such as

GPRS (Global Packet Radio Service) are alreadyavailable in some parts of Europe.

Work has already begun on the development of

fourth generation (4G) technologies in Japan.



The data are Packet-based which provides several

advantages over the existing circuit-switched

techniques. These techniques are used for carryingmobile voice. It allows higher call volumes and

support for multimedia data applications, such as

video and photography.

The charges are based on amount of data transmittedand not on time taken to connect to the network.

3 G network is one of the leading technologies in

today¶s wireless technology. This service is

available with any wireless phones. Verizon isthe first one to use this. It was first implemented

on CDMA phones .now this service is coming

soon with GSM. If we describe 3g is nothing but

fast stream and high bandwidth.

2.Pictures

You can take and send pictures to your friends and colleagues

faster than ever before. A 3G phone is 30 times quicker than a

GPRS phone.

3.Games

You can play even faster and better games with a 3G phone.



4.Location Services

You have access to location based services which can show

you where you are. Also,You can find a recommended

service or place like a cinema.

5.Watch TV On Your 3G Phone

In Korea, users have access to TV channels via their 3G

phones already.

A great deal of potential exists for new

applications in the future as 3G packet based

networks will allow users to be on line all thetime. The capabilities of wireless networks in

terms of bandwidth must still, however, be

improved upon.



3G is an exciting new technology that is being

incorporated into mobile devices across the

globe. Users are now able to make person-to- person calls, download data and do a variety of

other tasks they never imagined possible all via

their 3G cell phones.
