PROFILE

MEANING OF 3G

3G refers to the “third generation” of developments in wireless technology,

especially mobile communications. 3G technologies enable network

operators to offer users a wider range of more advanced services while

achieving greater network capacity.

Third generation (3G) wireless networks will offer faster data transfer rates

than current networks.

A general term that refers to technologies that offer increased capacity and

capabilities delivered over digital wireless networks.

digital wireless phones. An updated GSM system that allows high-speed

data transfers as well as voice communications.

Simplex vs. Duplex

When people use walkie-talkie radios to communicate, only one person can

talk at a time (the person doing the talking has to press a button). This is

because walkie-talkie radios only use one communication frequency - a form

of communication known as simplex:

4

Simplex: Using a walkie-talkie you have to push a button to talk one-way.

of course, this is not how mobile phones work. Mobile phones allow

simultaneous two-way transfer of data - a situation known as duplex (if

Omore than two data streams can be transmitted, it is called multiplex):

5

Duplex: Allows simultaneous two-way data transfers.

The communication channel from the base station to the mobile device is

called the downlink, and the communication from the mobile device back

to the base station is called the uplink. How can duplex communication be

achieved? Well, there are two possible methods which we will now

consider: TDD and FDD.

Symmetric Transmission vs. Asymmetric Transmission

6

Data transmission is symmetric if the data in the downlink and the data in

the uplink is transmitted at the same data rate. This will probably be the case

for voice transmission - the same amount of data is sent both ways.

However, for internet connections or broadcast data (e.g., streaming video),

it is likely that more data will be sent from the server to the mobile device

(the downlink).

FDD transmission is not so well suited for asymmetric applications as it uses

equal frequency bands for the uplink and the downlink (a waste of valuable

7

spectrum). On the other hand, TDD does not have this fixed structure, and

its flexible bandwidth allocation is well-suited to asymmetric applications,

e.g., the internet .For example, TDD can be configured to provide 384kbps

for the downlink (the direction of the major data transfer), and 64kbps for

the uplink (where the traffic largely comprises requests for information and

acknowledgements)..

The 3G network might be divided up in hierarchical fashion:

Macro cell - the area of largest coverage, e.g., an entire city.

Micro cell - the area of intermediate coverage, e.g., a city centre.

Pico cell - the area of smallest coverage, e.g., a "hot spot" in a hotel or

airport.

8

aller regions s(shorter ranges) allow higher user density and

faster transmission rates. This is why they arWhy is there this

sub-division of regions? It is because sme called "hot spots".

HISTORY

Canada and the USA, telecommunication companies use W-CDMA

technology with the support of around 100 terminal designs to operate 3G

mobile networks.

In Europe, mass market commercial 3G services were introduced starting in

March 2003 by 3 (Part of Hutchison Whampoa) in the UK and IThe 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

October 1, 2001, although it was initially somewhat limited in scope;

broader availability was delayed by apparent concerns over reliability. The

second network to go commercially live was by SK Telecom in South Korea

on the 1xEV-DO technology in January 2002. By May 2002 the second

South Korean 3G network was by KTF on EV-DO and thus the Koreans

were the first to see competition among 3G operators.

The first European pre-commercial network was at the Isle of Man by Manx

Telecom, the operator then owned by British Telecom, and the first

commercial network in Europe was opened for business by Telenor in

December 2001 with no commercial handsets and thus no paying customers.

These were both on the W-CDMA technology.

10

The first commercial United States 3G network was by Monet Mobile

Networks, on CDMA2000 1x EV-DO technology, but this network provider

later shut down operations. The second 3G network operator in the USA was

Verizon Wireless in October 2003 also on CDMA2000 1x EV-DO and this

network has grown strongly since then.

The first pre-commercial demonstration network in the southern

hemisphere was built in Adelaide, South Australia by m.Net Corporation in

February 2002 using UMTS on 2100 MHz. This was a demonstration

network for the 2002 IT World Congress. The first commercial 3G network

was launched by Hutchison Telecommunications branded as three in April

2003.

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, Canataly. The

European Union Council suggested that the 3G operators should cover 80%

of the European national populations by the end of 2005.

Roll-out of 3G networks was delayed in some countries by the enormous

costs of additional spectrum licensing fees. In many countries, 3G networks

do not use the same radio frequencies as 2G, so mobile operators must build

entirely new networks and license entirely new frequencies; an exception is

the United States where carriers operate 3G service in the same frequencies

as other services.

The license fees in some European countries particularly high, bolstered by

government auctions of a limited number of licenses and sealed bid auctions,

11

and initial excitement over 3G's potential. Other delays were due to the

expenses of upgrading equipment for the new systems.

By June 2007 the 200 millionth 3G subscriber had been connected. Out of 3

billion mobile phone subscriptions worldwide this is only 6.7%. In the

countries where 3G was launched first - Japan and South Korea - 3G

penetration is over 70%. In Europe the leading country is Italy with a third

of its subscribers migrated to 3G. Other leading countries by 3G migrations

include UK, Austria, Australia and Singapore at the 20% migration level. A

confusing statistic is counting CDMA 2000 1x RTT customers as if they

were 3G customers. If using this definition, then the total 3G subscriber base

would be 475 million at June 2007 and 15.8% of all subscribers worldwide.

Still several major countries such as Indonesia have not awarded 3G

licenses and customers await 3G services. China delayed its decisions on 3G

for many years. China announced in May 2008, that the telecoms sector was

re-organized and three 3G networks would be allocated so that the largest

mobile operator, China Mobile, would retain its GSM customer base.

China Unicom would retain its GSM customer base but relinquish its

CDMA2000 customer base, and launch 3G on the globally leading

WCDMA (UMTS) standard. Finally in January 2009, Ministry of industry

and Information Technology of China have awarded licenses of all three

standards -SCDMA to China Mobile, WCDMA to China Unicom and

CDMA2000 to China Telecom.

In November 2008, Turkey has auctioned four IMT 2000/UMTS standard

3G licenses with 45, 40, 35 and 25 MHz top frequencies. Turk cell has won

the 45MHz band with its €358 million offer followed by Vodafone and Avea

12

leasing the 40 and 35MHz frequencies respectively for 20 years. The

25MHz top frequency license remains to be auctioned.

The first African use of 3G technologies was a 3G video call made in

Johannesburg on the Vodacom network in November 2004. The first

commercial launch of 3G in Africa was by EMTEL in Mauritius on the W-

CDMA standard. In North African Morocco in late March 2006, a 3G

service was provided by the new company Wana.

Rogers Wireless began implementing 3G HSDPA services in eastern Canada

early 2007 in the form of Rogers Vision. Fido Solutions and Rogers

Wireless now offer 3G service in most urban centers.

Evolution from 2G to 3G

2G networks were built mainly for voice data and slow transmission. Due to

rapid changes in user expectation, they do not meet today's wireless needs.

Evolution from 2G to 3G can be sub-divided into following phases:

From 2G to 2.5G (GPRS)

The first major step in the evolutio to 3G occurred with the introduction of

General Packet Radio Service (GPRS). So the cellular services combined

with GPRS became' 2.5G.'

15

GPRS could provide data rates from 56 Kbit/s up to 114 Kbit/s. It can be

used for services such as Wireless Application Protocol (WAP) access, Short

Message Service (SMS), Multimedia Messaging Service (MMS), and for

Internet communication services such as email and World Wide Web access.

GPRS data transfer is typically charged per megabyte of traffic transferred,

while data communication via traditional circuit switching is billed per

minute of connection time, independent of whether the user actually is

utilizing the capacity or is in an idle state.

GPRS is a best-effort packet switched service, as opposed to circuit

switching, where a certain Quality of Service (QoS) is guaranteed during the

connection for non-mobile users. It provides moderate speed data transfer,

by using unused Time division multiple access (TDMA) channels.

Originally there was some thought to extend GPRS to cover other

standards, but instead those networks are being converted to use the

GSM standard, so that GSM is and newer releases. It was originally

standardized by European Telecommunications Standards Institute (ETSI),

but now by the 3rd Generation Partnership Project (3GPP)., .m

From 2.5G to 2.75G (EDGE)

GPRS networks evolved to EDGE networks with the introduction of 8PSK

encoding. Enhanced Data rates for GSM Evolution (EDGE), Enhanced

GPRS (EGPRS), or IMT Single Carrier (IMT-SC) is a backward-compatible

digital mobile phone technology that allows improved data transmission

16

rates, as an extension on top of standard GSM. EDGE can be considered a

3G radio technology and is part of ITU's 3G definition, but is most

frequently referred to as 2.75G. EDGE was deployed on GSM networks

beginning in 2003—initially by Cingular (now AT&T) in the United States.

EDGE is standardized by 3GPP as part of the GSM family, and it is an

upgrade that provides a potential three-fold increase in capacity of

GSM/GPRS networks. The specification achieves higher data-rates by

switching to more sophisticated methods of coding (8PSK), within existing

GSM timeslots.

.

From 2.75G to 3G (pure 3G)

From EDGE networks the introduction of UMTS networks and technology

is called pure 3G. 3G Bandwidth 5 MHz

Data rates

The ITU has not provided a clear definition of the data rate users can expect

from 3G equipment or providers. Thus users sold 3G service may not be

able to point to a standard and say that the rates it specifies are not being

met. While stating in commentary that "it is expected that IMT-2000 will

provide higher transmission rates: a minimum speed of 2Mbit/s and

maximum of 14.4Mbit/s for stationary users, and 348 Kbit/s in a moving

17

vehicle, the ITU does not actually clearly specify minimum or average rates

or what modes of the interfaces qualify as 3G, so various rates are sold as

3G intended to meet customers expectations of broadband speed. It is often

suggested by industry sources that 3G can be expected to provide 384 Kbit/s

at or below pedestrian speeds, but only 128 Kbit/s in a moving car. While

EDGE is part of the 3G standard, some phones report EDGE and 3G

network availability as separate functionality.

Network standardization

The International Telecommunication Union (ITU) defined the demands

for 3G mobile networks with the IMT-2000 standard. An organization

called 3rd Generation Partnership Project (3GPP) has continued that

work by defining a mobile system that fulfills the IMT-2000 standard. This

system is called Universal Mobile Telecommunications System (UMTS).

18

Empowering Communities Worldwide through 3G

Information and Communication Technology (ICT) is the world’s leading

consumer product. In its relatively short lifetime, the reach of technology has

already spurred tremendous changes in the way people interact and has re-

defined relative distances. As a central component of ICT, wireless

technology, in particular, has proven to have intrinsic social and economic

benefits, and its convergence with other sectors — entertainment, Internet,

navigation — has brought about a new level of access and convenience to

people all over the world.

The wireless industry’s commitment to worldwide The developed world is already

accustomed to the advantages of advanced and readily available ICT, to the

point that technology’s pervasive presence renders it expected and

commonplace. But for countries still struggling to develop socially and

economically, the ways that proliferating wireless access can positively

impact populations and economies are inspiring.

In the last few years, mobile phones have become more than just a tool of

convenience in emerging nations; they now have the capability to empower

people worldwide through immediate connectivity that eliminates isolation

and enables learning and growth.

We are at the early stages of a world that benefits from providing ubiquitous

connectivity to its entire people. The vision our industry shares is one of a

fully connected society, a global community that has access to information

and one another, regardless of location or economic position. More times

than not, powerful visions such as these are easier to conceive than to

implement. However, if there is one thing I’ve witnessed during my career,

it is that our industry has risen to meet the tremendous challenges set before

19

us. Who could have imagined that the bulky, expensive cellular phones of

the early days, which could only be used by the wealthiest people, would

morph into the tiny devices of USD 20 that are spreading voice and data

communications throughout places like rural India?

connectivity is employed with an eye towards global improvement,

especially in developing countries that are lacking basic necessities.

Significant initiatives have been executed in the categories of education,

health care, public safety, the environment and entrepreneurship, setting up a

solid base for continued development. Through Qualcomm’s Wireless Reach

initiative, I have experienced how the industry can work together with local

and global partners to bring wireless technology to communities in need to

develop better health care, improve education and provide new business

opportunities. While a mobile phone can never substitute for a well-trained

teacher or doctor, the capabilities it offers to communities that have neither

are significant.

Empowering Entrepreneurs

The role of wireless technology in furthering economies and businesses is

increasingly critical and an important economic stimulus. Research has

established a strong correlation between ICT development and overall eco-

nomic growth. Improvements in either mobile phone or Internet penetration

are strongly correlated with significant improvements to a country’s GDP: A

1 percent increase in Internet penetration in developing countries is

correlated with an increase of 10.5 percent of average per capita income. i

“I have experienced how the industry can work together with local and

trained teacher or doctor, the capabilities it offers to communities that

have neither are significant.”

21

Whether it is found in a mobile phone, fixed wireless phone, wireless

modem or data card, 3G is the most affordable way to provide voice and

data access to rural areas where landline access is limited or simply doesn’t

exist. For governments, wireless broadband is a fundamental way of

increasing their countries’ teledensity and Internet penetration rates. For

citizens, 3G may represent their first (or only) experience in accessing the

Internet, primary way of making a phone call or vital tool to improve their

economic condition.

Just as I have seen 3G make a fundamental difference in the way children

learn and are taught, I have seen 3G empower entrepreneurs in developing

communities that had limited or no telecommunications access. In Neglasari,

a small village on the island of Java in Indonesia, Mrs. Halimah serves her

community as a Village Phone Operator. Members of the community

recognize Mrs. Halimah and trust her to give them affordable mobile phone

services.

Mrs. Halimah’s important role in connecting her neighbors with their

families is a result of her being able to leverage micro-financing to purchase

a “business in a box” consisting of a wireless 3G CDMA-based phone,

marketing materials, tariff posters, business cards and training. These

entrepreneurs can operate their businesses in rural areas where

telecommunication services did not previously exist, renting the use of their

phones within their communities on a per-call basis. From communication

with relatives, to updates on commodity prices and knowledge of new

business opportunities, the information that these villagers now have

available to them is making a very real impact on their lives.

22

Enabling Health Care

In the southern province of Phang Nga, in Thailand, beautiful limestone rock

formations jut out of the Andaman Sea. There, people have built floating

villages, creating the habitable islands of Koh Panyee and Koh Yoa Yai. But

this beautiful and peaceful scene can easily become the backdrop for a

difficult situation when villagers from this remote region face health

emergencies that require assistance from the closest hospital, which is at

least 45 minutes away by boat.

The challenge of providing adequate health care to remote and rural areas of

the population is an ideal example of how 3G technologies have proved to

be effective. Koh Panyee and Koh Yao Yai have been equipped with EV-

DO high-speed wireless services, in collaboration with Thailand’s CAT

Telecom. Two remote health clinics are now connected to the mainland

hospital with telemedicine equipment, by which staff can send diagnostic

data in graphs and images.

We can significantly contribute to the development of rural communities by

joining forces with other organizations from outside the wireless industry

that also are committed to making a difference in the world. Together, we

are already creating sustainable projects that empower these communities to

enjoy an improved quality of life.

23

A Brighter, Connected Future

The ICT industry is poised to affect monumental change in industries and

geographies worldwide, but its potential to initiate immediate and impact

socio-economic development in developing countries is especially signifi-

cant. The improvements that can be achieved in education, health care and

burgeoning entrepreneurship will not only progress the future of countries

and their communities, but also give testament to the robust promise and

strength of the technology.

Through continued industry collaboration and open innovation, we can help

drive real growth and advancement for citizens globally. If we continue our

history as an industry that spreads innovative new devices, networks and

applications worldwide, the ability to improve the lives of millions around

the world is no further away than our fingertips.

24

EXPANDING EDUCATION 3G Internet access has the unique ability

to instantly and effectively bring knowledge and resources to schools that

are under-funded and under-served.

sI have seen how 3G can transform lives by enhancing the ways by which

people learn. With 3G access, teachers and students can explore the world

like never before – via the Internet. We’ve witnessed newfound success in

schools equipped with 3G wireless Internet access on computers and

Smartphone’s. The technology has opened up an entirely new world.

Teachers are amazed bys how quickly they can download and access

materials on the Internet, while students are able to visit faraway lands

virtually or join classroom discussions and receive lesson plan assistance

when away from school.

During a project launch in Guatemala, another Qualcomm executive was

showing an elementary school student how to access the Internet from a

computer. He asked the girl about her favorite animal, a rabbit, and im-

mediately brought up a picture of a rabbit with a world map that identified

all the countries where those rabbits lived – including Guatemala. As he

continued to tell her about the power of the Internet, she began looking

around the room and under the desk.

After all, 3G networks go beyond the delivery of voice connectivity to

address issues of public importance such as Internet connectivity, education,

entrepreneurship, health care and public safety in a sustainable, efficient and

cost effective manner.

25

Issues

Although 3G was successfully introduced to users across the world, some

issues are debated by 3G providers and users:

Expensive input fees for the 3G service licenses & agreements

Numerous differences in the licensing terms

Large amount of debt currently sustained by many telecommunication

companies, which makes it a challenge to build the necessary

infrastructure for 3G

Lack of member state support for financially troubled operators

Expense of 3G phones

Lack of buy-in by 2G mobile users for the new 3G wireless services

Lack of coverage, because it is still a new service

, including Internet High prices of 3G mobile services in some

countries access. Current lack of user need for 3G voice and

data services in a hand-hed d

26

Security

3G networks offer a greater degree of security than 2G predecessors. By

allowing the UE to authenticate the network it is attaching to, the user can be

sure the network is the intended one and not an impersonator. 3G networks

use the KASUMI block crypto instead of the older A5/1 stream cipher.

However, a number of serious weaknesses in the KASUMI cipher have been

identified.

In addition to the 3G network infrastructure security, end to end security

is offered when application frameworks such as IMS are accessed, although

this is not strictly a 3G property.
