Introduction to 3G

3G STANDS FOR :

THIRD GENERATION OF WIRELESS COMMUNICATIONS.

MOBILE TELEPHONY + INTERNET SERVICES = 3G


8/24

Whats new about 3G:

IT MERGES ALL THE STANDARDS INTO ONE.

Europe pursued NMT and TACS for analog and GSM for digital,

North America pursued AMPS for analog and a mix of TDMA,CDMA and GSM for digital. 3G will bring these incompatible

standards together.


9/24

3G is designed to deliver:

# A wide range of market- focused applications.

# Long-term market-driven creativity driving genuine market

demand .

# Advanced, lightweight, easy-to-use terminals with intuitive

interfaces Instant, real-time multimedia communications.

# Global mobility and roaming.

# A wide range of vendors and operators, offering choice,

competition and affordability.

# High-speed e-mail and Internet access.

3G Standards

The idea behind 3G is to unify the disparate standards that todays

second generation use.

The Operators Harmonization Group (OHG) - a group of major

operators from all parts of the world - has played a key role in thisprocess, and agreed on a set of standards in May 1999.


11/24

In fact the final ITU recommendations forIMT-2000stipulated five

terrestrial radio interface standards when DECT (IMT FT) and EDGE(IMT SC

orIWC 136) are included

TITLE ORIGIN SUPPORTERS

IMT DS

WCDMA

Direct

Spread FDD

Based on the first

operational mode of ETSIs

UTRA (3G Terrestrial Radio

Access) program

Japans ARIB (Association of

Radio Industries and

Businesses, the Japanese

standards setting body) and

GSM network operators andvendors.

IMT MC

cdma2000

Multi-Carrier

FDD

Based on the cdma2000

RTT proposal from the US

Telecom Industry Association

(TIA).

Consists of the 1XRTTand 3XRTTcomponents

Cdma One operators and

members of the CDMA

Development Group (CDG).

Likely to be deployed in the U.S.A

IMT TC

UTRA TDD

(Time

Division

Duplex)

The second operational

mode of ETSIs UTRA (3G

Terrestrial Radio Access) RTTproposal.

An unpaired

band solution to better andfacilitate

indoor cordlesscommunications.

Harmonized with Chinas TD-SCDMA

RTT proposal. Will work in China

transmission speed:144kbpsspeed is expected and by 2005 the speedwould be of 2mbps

INTERNET EVERYWHERENEW APPLICATIONS, BETTER APPLICATIONS.

3G NETWORKS - The complexities behind them.

The core network is the physical network infrastructure to which the radioaccess network is connected in a mobile network.

A radio access network is the portion of a mobile network that handlessubscriberaccess, including radio base stations and other nodes.

In the case of 3G, a different approach is being taken. There is onestandardization process for the radio network and another for the core network.

The 3G radio access network will comprise a RNC (Radio Network Controller)and Node B.


14/24

What would a 3g core network look like


15/24

Where is the new radio spectrum?

International standards and regulatory bodies have set aside radiofrequency in the 2GHz band.

In 1992, theWorld Administrative Radio Conference (WARC)

allocated 230MHZ of new radio spectrum to terrestrial and satellite

services. Of this, the ITU has set aside 155MHZ in the 2GHZ band for

terrestrial 3G services, as shown in the chart.


16/24

Applications:

AudioVideo

Voice over Internet Protocol(VOIP)

Still images

Moving images

Virtual Home EnvironmentMobile Commerce

Electronic agents

Home automation systems

Downloading software

Interactive video

(Video Conferencing,Telemedicine,TelelearningVirtual reality etc)

When will 3G be rolled out?

NTTDoCoMo already launched the world's first commercialised third-

generation "FOMA" mobile communication service on October 1, 2001.

"FOMA" is the name used in Japan for NTTDoCoMo's 3G service.

The key threats to 3G include:

Limited spectrum.

Complexity.

High Costs.

Working with data

.

Killer Content.

Security and Privacy

Alternate technologies.

Wide Area availability.


20/24

Inspite OfThe Doubts ,Delays And Debts AssociatedWith 3g

Service ProvidersWill Make 3g Succeed Simply Because They HaveAlready Invested Too Much In The New Technology To Let It Fail

3GWONTHAPPENOVERNIGHT.. BUT AS THE SYSTEMS,

EQUIPMENT, AND SERVICES ARE STARTING TO EMERGE, AND

WELL SEE 3G STARTTO BLOSSOM OVERTHE NEXT YEAR OR

TWO.

So basically 3G has to work!!!!


21/24

Who can access 3G service?

To use 3G users specifically need:

A mobile phone or a terminal which supports 3G

A subscription to a mobile network which provides 3G

Knowledge of how to send/receive information using their specific

model of mobile phone and hardware and software requirements. A destination to send and receive information using 3G.


22/24

What will future 3G terminals be like??

Many of these will have larger screens to display Internet pages or the

face of the person being spoken to.

There will be smaller "smart-phones" with limited web browsing and e-

mail capabilities.

Addition of mobile communication facilities to laptops and palmtops willspeed up the convergence of communications and computing

There will be videophones, wrist communicators, palmtop computers, and

radio modem cards for portable computers.

Innovative new voice based interfaces will allow people to control their

mobile communication services with voice commands.

Mobile services will be built into business equipment, vehicles and

household appliances, for dedicated applications.


23/24

THE FUTURE..

Advent of 4G is expected in 2010.

Three dimensional virtual reality will be enabled for the first time- imagine

personal video avatars and realistic holograms the ability to feel as if you are

present at an event even if you are not .

People, places and products will be able to interact, as the cyber and real

worlds merge.

3G is a substantial leap forward in mobile bandwidth and capacity.

4G will be another giant leap forward providing unprecedented broadband

communications
