3G: International Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a generation of standards for mobile phones and mobile telecommunications services fulfilling specifications by the International Telecommunication Union.

3G is the third generation of wireless technologies. It comes with enhancements over previous wireless technologies, like high-speed transmission, 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.

History:The first pre-commercial 3G network was launched by NTT DOCOMO in Japan branded FOMA, in May 2001 on a pre-release of W-CDMA technology.

The first commercial launch of 3G was also by NTT DOCOMO in Japan on 1 October 2001, although it was initially somewhat limited in scope.

The NOKIA 6650, an early UMTS handset.

Features:

Data rates: ITU While stating in commentary of data rates - "it is expected that IMT-2000 will provide higher transmission rates: a minimum data rate of 2 Mb/s for stationary or walking users, and 384 Kb/s in a moving vehicle.“

Security: 3G networks offer greater security than their 2G predecessors. By allowing the UE (User Equipment) to authenticate the network it is attaching to, the user can be sure the network is the intended one and not an impersonator.

Advantages: 3G has the following enhancements over 2.5G and previous networks:

Several times higher data speed.

Enhanced audio and video streaming.

Video-conferencing support. Web and WAP browsing at higher speeds. IPTV (TV through the Internet) support.

The most interesting and useful aspect of 3G wireless technology is its ability to unify existing cellular standards such as GSM, CDMA and TDMA.

Applications:

The 3G devices give rise to applications not previously available to mobile phone users. Some of the applications are:

Mobile TV – a provider redirects a TV channel directly to the subscriber's phone where it can be watched.

Video on demand – a provider sends a movie to the subscriber's phone.

Video conferencing – subscribers can see as well as talk to each other

Tele-medicine – a medical provider monitors or provides advice to the potentially isolated subscriber.

Location-based services – a provider sends localized weather or traffic conditions to the phone, or the phone allows the subscriber to find nearby businesses or friends. For Business -High speed Teleworking -Sales Force Automation -Real time Financial Information

Adoption:

In December 2007, 190 3G networks were operating in 40 countries and 154 HSDPA networks were operating in 71 countries, according to the Global Mobile Suppliers Association (GSA). In Asia, Europe, Canada and the USA, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks.

3G IN VARIOUS COUNTRIES:

• Europe• Canada• Iraq• China• North Korea• India

Factors of 3G

GSM (Global System for Mobile Telecommunication) - wide spread implementation of data comm. - roaming arrangements. GPRS (General Packet Radio Service) -packed based data network. -well suited for non real time internet usage including retrieval email, faxes &web browsing. -supports multiuser network on dedicated GSM radio channels. -content handling.

CDMA (Code Division Multiple Access) -code channels are transmitted at full data. -convolutional & turbo coding techniques used -multilevel modulation format TDMA (Time Division Multiple Access) -channel access method for shared medium networks. -time slots are used.

FDMA (Frequency Division Multiple Access) - combination of multiple signals. - way of separating radio signals.

3G in INDIAFrom the time of telegraphs Indian telecom sector has witnessed an immense growth and has diversified into various segments like, Fixed Line Telephony, mobile telephony, GSM, CDMA, WLL etc. The telecom industry is growing at a fast pace introducing newer technologies. Even the network operators and handset providers are also coming up with newer value added services and advanced technology cell phones with multimedia applications.

Now it's time to welcome the much-awaited 3G Technology. Bharat Sanchar Nigam Limited has launched the technology on 19th of May,2010. Not only the network providers but also the handset providers in are waiting eagerly for the launch of 3G to earn very high revenues from the value added services provided by the technology.

Future Developments

3.5G - i.e HSDPA(high speed downlink package access) -adaptive modulation & coding. - fast scheduling. - backward compatibility with 3G. 4G: Anytime,Anywhere Connection -MAGIC - Mobile multmedia communication. - Anywhere ,anytime with anyone. - Global mobility support. - Integrated wireless solution. - Customized personal service

In India ,communication minister Mr.Dayanidhi Maran has announced a national centre of excellence to work in 4G arena.

Conclusion: The bandwidth and location information available to 3G devices gives rise to a broad avenue of applications. Thereby, making an exponential growth in the services provided in the telecom sector.
