3G in India
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.
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
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.“
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.
3G has the following enhancements over
2.5G and previous networks:
Several times higher data speed.
Enhanced audio and video streaming.
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.
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
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.

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:
• North Korea
Factors of 3G
(Global System for Mobile Telecommunication)
- wide spread implementation of data comm.
- roaming arrangements.
(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
(Code Division Multiple Access)
-code channels are transmitted at full data.
-convolutional & turbo coding techniques used
-multilevel modulation format
(Time Division Multiple Access)
-channel access method for shared medium
-time slots are used.
(Frequency Division Multiple Access)
- combination of multiple signals.
- way of separating radio signals.
3G in INDIA
From 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
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.
- i.e HSDPA(high speed downlink package access)
-adaptive modulation & coding.
- fast scheduling.
- backward compatibility with 3G.
4G: Anytime,Anywhere Connection
- 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.
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.
