History of GSM

GSM began in 1991

GSM was a European wide project frombeginning

GSM used in more than 170 countries

Originated from 1G ->2G->2.5G->3G

3G version is named as UMTS 3G Network provide higher capacity than

the older generations

MOBILE COMMUNIC TION

1 G -analog (cellular revolution)

- only mobile voice services

2 G - digital (breaking digital barrier)- mostly for voice services & data delivery

possible

3 G - Voice & data ( breaking data barrier)

- Mainly for high speed data services where voice

will also be possible

Beyond 3G -Wide band CDMA ?

- But

surely higher data rates


6/44


First Generation & Second GenerationMobile System

Analog cellular systems are commonly referred toas first generation systems.

The digital systems currently in use, such as GSM,

PDC, CDMA one (IS-95), and US-TDMA (IS-136)are second generation system. These systemshave enabled voice communications to gowireless and customers are increasing finding

value also in other services such as textmessaging and access to data networks.

2G Mobile systems

2G Cellular Networks were first commerciallylaunched in Finland by Radiolinja in 1991

2G Cellular Networks are fully digital

2G Cellular Networks are very secure use

encryption

2G Cellular Networks provide basic data services

also

Have advanced Fraud Mechanisms

Spectrum for 2G Systems

At present GSM is operating in 900 MHz band - 890-915 MHz Uplink

935-960 MHz Downlink 1800 MHz band - 1710-1785 MHz Uplink

1805-1880 MHz Downlink 1900 MHz band - 1850-1910 MHz Uplink

1930-1990 MHz Downlink




No Global standards

No common frequency band Low information bit rates

LIMITATIONS OF 2nd GENERATION SYSTEMS

Low voice quality

No support of Video

Various categories of systems to meet specificrequirements



Data Rates too slowabout 9.6 kbps

Connections setup too long & complicated

Proves expensive for bursty traffic utilization

Inefficient resource utilization for bursty

traffic

No efficient method for packet transfers

GPRS..

GPRS is a new set of GSM-bearerservices that provide packet mode

transmission within the GSMnetwork & interconnects withexternal packet data networks.

General Packet Radio Service

2.5 G system standardized by ETSI

Migration Path to 3G Networks

Very Little change to GSM infrastructure

Direct support for Data Network

Better Billing Mechanisms

No need to reorganize spectrum

Introduce packet-switched routing functionality Better data transfer rates

Low cost and connectivity-oriented

EDGE enhances GPRS services

By bringing higher speedHigher video quality

Lower download time

Faster access

Enriching the end-user experience

Increase addiction

Boost usage of the services

and meeting your challenges

Attract new customers and lock-in existing customers

Increase the ARPU

3G Mobile systems

3G is designed to enhance the end user experience

many-fold Superior voice quality

Broadband data speeds

Certain applications are possible only with 3G services

Multimedia

High speed mobile broadband

3G services allows simultaneous use of voice and high

speed data rates

In 2G, simultaneous voice and data usage is restricted

Basics & Context

Third Generation System

Third generation systems are designed formultimedia communications;

With them person to person communication

can be enhanced with high quality imagesand video,

And access to information and services onpublic and private networks will beenhanced by higher data rates.

What is WCDMA?

One of the Access type used in RF network ofUMTS ( Universal Mobile TelecommunicationServices) for migration to GSM to UMTS ( 2 G to

3 G) network. It is different from conventional CDMA access (
