The main objective of the 3G is to provide

faster communication service which

include voice, fax, multimedia, video

calling.

And to provide high speed internet access,

data, video and CD-quality music.


3/33

1G Technology

2G Technology

2G+ Technology


4/33

Analog radio signals

Implemented in North America

Known as Analog Mobile Phone Systems(AMPS) based on circuit-switchedtechnology and designed for voice, not

data. Technology used Frequency Division

Multiple Access (FDMA)


5/33

It has low capacity, unreliable handoff, poorvoice links, and no security at all since voicecalls were played back in radio towers,

making these calls susceptible to unwantedeavesdropping by third parties.

If a user moved to a different cell area, thecall was often lost as handoffs would not

always occur correctly. Users often had to re-dial numbers or reconnect to the base stationin the new cell area.


6/33

Used Digital Radio Signals

Mostly based on circuit switched

technology

These are digital and expand the range of

applications to more advanced voice

services.


7/33

2G technologies may be categorized by

whether they are based on time division

multiple access (TDMA) or code division

multiple access (CDMA)

2G makes use of a CODEC (compression-

decompression algorithm) to compress

and multiplex digital voice data.


8/33

It transmitted data through digital signals

Offered additional services such as SMS

and e-mail.

Less Power required

Error checking

improved sound quality


9/33

In less populous areas, the weaker digitalsignal will not be sufficient to reach a cell

tower.

Low band width

Low data transmission speed

May not support Multimedia messages

not suitable for web browsing and

multimedia application


10/33

It is as same as 2G Technology

But it is based on Packet switching

technology

It increases the data communication

speed up to 384kbps

Based on : General Packet Radio Service(GPRS) and Enhanced Data Rates for

Global Evolution (EDGE) technologies.


11/33

The GPRS and EDGE are data

transmission techniques

GPRS has the data transmission speed upto 114 kbps

EDGE has up to 384 kbps

2G+ networks support services such asMMS, SMS, mobile games, and search

and directory.

3G is the third generation of wirelesstechnologies.

It comes with enhancements over previouswireless technologies, like high-speedtransmission, advanced multimedia accessand global roaming.

3G is mostly used with mobile phones andhandsets as a means to connect the phone tothe Internet or otherIP networks in order tomake voice and video calls, to download andupload data and to surf the net.

Services include:

Global roaming

Superior voice quality and video conference

Data always addon services (e-mail,

personal organizer, etc.)

Information for web surfing, music, news,

corporate intranet, transportation service etc. Purchasing on-line shopping / banking,

ticketing, gambling, games, etc


16/33

A device with 3G compatibility, that may

be mobile phone or data card.

3G phones commonly have two cameras

since the technology allows the user to

have video calls


17/33

First pre-commercial 3G network waslaunched by Japan in May 2001

First post-commercial launch by Japan in Oct2001

The second network is SK Telecom of SouthKorea in Jan 2002

First commercial 3G network of US is Monet

Mobile Network on CDMA 2000 Second network id Verizon Wireless in Oct2003 on CDMA 2000


18/33

Japan is the first country having

introduced 3G nationally, and in Japan the

transition to 3G is being largely completedduring 2005/2006


19/33

1. Enhanced multimedia(voice, data, video,and remote control)

2. Usability on all popular modes (cellular

phone, e-mail, videoconferencing, andweb browsing)

3. Broad bandwidth and high speed

(upwards of 2Mbps)4. Routing flexibility(repeater, satellite, LAN)

5. Roaming capability


20/33

3G wireless networks consist of a Radio

Access Network (RAN) and a core

network. The core network consists of a

packet-switched domain, which includes3G SGSNs(Serving GPRS Support Node)

and GGSNs(Gateway GPRS Support

Node). In this used both packet switching and

circuit switching technologies

Brief Description about Protocols

1.Global Mobility Management (GMM): protocol thatincludes attach, detach, security, and routing area updatefunctionality.

2.Node B Application Part (NBAP): provides proceduresfor paging distribution, broadcast system information andmanagement of dedicated and logical resources.

3. Packet Data Convergence Protocol (PDCP): mapshigher level characteristics onto the characteristics of theunderlying radio-interface protocols. PDCP also providesprotocol transparency for higher layer protocols.

4. Radio Link Control (RLC): provides a logical linkcontrol over the radio interface.

5. Medium Access Control (MAC): controls the accesssignaling (request and grant) procedures for the radiochannel.

6. Radio resource Control (RRC): manages theallocation and maintenance of radio communication paths.

7. Radio Access Network Application Protocol(RANAP): encapsulates higher layer signaling. Managesthe signaling and GTP connections between RNC and

3G-SGSN, and signaling and circuit-switched connectionsbetween RNC and 3G MSC.

8. Radio Network Service Application Part (RNSAP):provides the communication between RNCs.

9.GPRS Tunnel Protocol (GTP): protocol that tunnels the

protocol data units through the IP backbone by addingrouting information. GTP operates on top of TCP/UDPover IP.

10. Mobile Application Part (MAP): supports signalingbetween SGSN/GGSN and HLR/AuC/EIR.


26/33

Two types of roaming.

1.Basic (inter-PLMN) Roaming

No handover between the involvednetworks

Subscriber services are determined by

capabilities of the visited network and HLRinformation.


27/33

2. Regional National roaming

When the Visited and the Home PLMNs

belong to the same country, specific

mechanisms may be required in order to

allow the access to only a part of the

visited network (regional roaming).


28/33

The main reason to use USIM is to offer

enhanced security to your customers,

because USIM is the only one supporting

3G Authentication.


29/33


30/33

More bandwidth, security, and reliability.

Support video calling

Fixed and variable data rates. High data rate for fast net accessing

Rich multimedia services

Always-online devices. 3G will use IPconnectivity, IP is packet based (not circuit

based).


31/33


32/33

3G environments offer the ability to deliver

mass-market, high-quality, wireless

multimedia applications that include

extraordinary capabilities such as location-based services and global roaming.
