3G
Definition of 3G:
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.
How is 3G Better?
3G has the following enhancements over 2.5G and previous networks: * Several times higher data
speed; * Enhanced audio and video streaming; * Video–conferencing support; * Web and WAP
browsing at higher speeds; * IPTV (TV through the Internet) support

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.
Roll–out of 3G networks was delayed in some countries by the enormous costs of additional
spectrum licensing fees. (See Telecoms crash.) 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 were particularly high,
bolstered by government auctions of a limited number of licenses and sealed bid auctions, and initial
excitement over 3G's potential. Other delays were due to the expenses of upgrading equipment for
the new systems.
T–Mobile, a major Telecommunication services provider has recently rolled out a list of over 120
U.S. cities which will be provided with 3G Network coverage in the year 2009.
Europe
In Europe, mass market commercial 3G services were introduced starting in March 2003 by 3 (Part
of Hutchison Whampoa) in the UK and Italy. The European Union Council suggested that the 3G
operators should cover 80% of the European national populations by the end of 2005.

History of Cellphone
History of Cell Phones The history of mobile phones records the development of interconnection
between the public switched telephone systems to radio transceivers. From the earliest days of
transmitting speech by radio, connection of the radio system to the telephone network had obvious
benefits of eliminating the wires. Early systems used bulky, high power consuming equipment and
supported only a few conversations at a time, with required manual set–up of the interconnection.
Today cellular technology and microprocessor control systems allow automatic and pervasive use of
mobile phones for voice and data. The transmission of speech by radio has a long and varied history

In 1969 Amtrak equipped commuter trains along the 225–mile New York–Washington route with
special pay phones that allowed passengers to place telephone calls while the train was moving. The
system re–used six frequencies in the 450 MHZ band in nine sites, a precursor of the concept later
applied in cellular telephones. [2] In December 1971, AT&T submitted a proposal for cellular
service to the Federal Communications Commission (FCC). After years of hearings, the FCC
approved the proposal in 1982 forAdvanced Mobile Phone System (AMPS) and allocated
frequencies in the 824–894 MHz band.[6] Analog AMPS was eventually superseded by Digital
AMPS in 1990. A cellular telephone switching plan was described by Fluhr and Nussbaum in 1973,
[7] and a cellular telephone data signaling system was described in 1977 by Hachenburg et al.[8] In
1979 a U.S. Patent 4,152,647 was issued to Charles A. Gladden and Martin H. Parelman, of Las
Vegas for an emergency cellular system for rapid deployment in areas where there was no cellular
service. Emergence of commercial mobile phone service Alongside the early developments outlined
above, a different technology was also growing in popularity. Two–way mobile radios (known as
mobile rigs) were used in vehicles such as taxicabs, police cruisers, and ambulances, but were not
mobile phones, because they were not connected to the telephone network. The first fully automated
mobile phone system for vehicles was launched in Sweden in 1960. Named

This hardware also contains memory chips onto which the software is loaded. The software residing
on the memory chip is also called the µfirmware¶. The embedded system architecture can be
represented as a layered architecture as shown in Fig. The operating system runs above the
hardware, and the application software runs above the operating system. The same architecture is
applicable to any computer including a desktop computer. However, there are significant
differences. It is not compulsory to have an operating system in every embedded system. For small
appliances such as remote control units, air conditioners, toys etc., there is no need for an operating
system and you can write only the software specific to that application. For applications involving
complex processing, it is advisable to have an operating system. In such a case, you need to
integrate the application software with the operating system and then transfer the entire software on
to the memory chip. Once the software is transferred to the memory chip, the software will continue
to run for a long time you don¶t need to reload new software. 2.2 Characteristics 1. Embedded
systems are designed to do some specific task, rather than be a general–purpose computer for
multiple tasks. Some also have real–time performance constraints that must be met, for reasons such
as safety and usability; others may have low or no performance requirements, allowing the system

Reliability in Smart Grids
In many areas of the United States, the only way a utility knows there's an outage is when a
customer calls to report it. A challenge faced by smart grid systems is to provide highly reliable
transmission to improve the energy efficiency of the system. If a proper command couldn't be send
in the event of an emergency it could result in disastrous consequences. As a result, quantitative
reliability evaluation of information infrastructures should be addressed.
A smart grid is a modernized electrical grid that uses analogues or digital information and
communications technology to gather and act on information, such as information about the
behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability,
economics, and sustainability of the production and distribution of electricity.
To provide the reliability of data communication of smart grids we are proposing wireless
communication infrastructure. In this paper we will discuss pros and cons along with the
applicability of wired, wireless and hybrid communication systems for the smart grid application.
For reliability we have to optimize both power consumption and power supply. Smart grid works on
the mechanism of data communication infrastructure. Smart grids has one of the most important
feature meter data management system which is designed to collect exchange and process the meter
data for optimization of power consumption and supply.

How Wireless Technology Has Changed Improved
Abstract: The purpose of this research paper is to demonstrate how much Wireless Technology has
really improved, since the year James Clerk Maxwell developed and explained the theory of
electromagnetic waves on 1865; And Heinrich Hertz put into practice Maxwell 's theory by
experimenting with electromagnetic waves–measuring their speed and wavelength between the
years 1885–1889; Until present days. As this type of technology grows, it is perceivable to what
extent people have learned how to manipulate electromagnetic waves at will. For the purpose of this
paper, I have done a very extensive research looking for remarkable improvements that would take a
substantial and detailed portion that would explain the what, when and how of each major
breakthrough, on the body of this research. Wireless Technology has become a very important part
of our daily lives–as individual users, groups, or even businesses–since radio waves were
discovered, and we learned how to manipulate it to some extent. It isn't odd to see a device which
doesn't depend of a cable to receive/transmit a signal or radio waves nowadays. We often see people
using smartphones, laptops without requiring any external connection to the LAN, or even our own
radios. All of these wouldn't be possible without the existence of Wireless Technology. But, has
there really been a whole deal of improvements on this type of technology? According to (Merriam–
Webster, Inc., n.d), to

Chapter 1
Introduction
The cellular technology has developed a long way from its existence in the early 1980's. In the past
few decades it has grown into one of the biggest market with the rise of cell phone users, the cellular
network providers and cell phone makers have grown in immense amount. Cellular technologies
have evolved from first generation (1G), second generation (2G), third generation (3G) and to its
current technology which is fourth generation (4G) which is also known as Long Term Evolution
(LTE). Fig 1.1 Evolution of Cellular technology
The first generation (1G) only provided users with voice communication in its second generation
(2G) the service was expanded to voice and data communication in which the system capacity was
also improved. Second generation or 2G wireless technology is also known as Global Systems for
Mobile Communications (GSM) and Code Division Multiple Access (CDMA). The third generation
(3G) was a revolution in the cellular technology the data rates increased immensely from 2G, 3G is
also known as Wideband CDMA (WCDMA) and CDMA–2000. The current cellular technology that
are in existence is fourth generation (4G) also known as Long Term Evolution (LTE), which can
theoretically provide data rates up to 100 Mbps.
Evolution of Cellular Technology
The first generation (1G) system was developed and implemented in 1981 in Norway which used
Advanced Mobile Phone System (AMPS), US and UK later followed similar technology for

By 2001, there were an estimated 128,000,000 subscribers in the US. THE CURRENT
CELLPHONE INDUSTRY Industry Structure During the late 90s, the number of subscribers
doubled every two years, wireless stocks grew as fast as those of many dot–coms, and IPOs raised
record amounts of money. These vertiginous events shaped the new telecommunications landscape
we know today (Exhibit 1– US Wireless Industry Statistics) However, recently things changed
dramatically as industry growth began to level off. Growth in new subscribers went from 50%
yearly to 15%–20% in 2002 and analysts predict a meager 10% for 2003 and stabilization in the low
single digits by 2009 (Exhibit 2 – Wireless Penetration). The first victim in this scenario was the
ARPU (Average Revenues per User). Companies enticed new subscribers by offering them "better
deals" while sacrificing margin. Before long, roaming revenues (fees a company receives when
another carrier's subscriber utilize its network) had become the most important ARPU growth
engine. Unfortunately this source of cash didn't last long. Recent statistics showed that in spite of an
increase in minutes of use, US roaming revenues consistently have declined approximately 5% year
to year (Exhibit 3 – Roaming Services). With high–margin revenues relegated to the history books,
wireless carriers focused their efforts on expanding their geographic availability, lowering their
service costs and ultimately

Disadvantages Of Wireless Technology
No doubt, in last few decades technologies involved in the communication systems have been
developed exponentially along with attractive features and facilities. Wireless communication
system is one of the biggest inventions of the century and its developments can be processed in
diﬀerent terms of generation having approx. 10 years for each one. At every step of each generation
is to provide to link with persons at every corner of globe with set of quality services. Today we are
in Fourth Generation; it is categorized based on its characteristic services and features like
transmission signals, data transmission rate, bandwidth frequency and nature of the services
provided. First generation (1G) is introduced in 1980, so each generation had been comes at the end
of every decade. First generation used analog signals, circuit switching and FDMA with 30 kHz
channels occupying the 824MHz 894MHz frequency band .First generation supports only voice
transmission .The data was not reliable; there were interrupted communication and few other
problems in First Generation [1]. Second Generation (2G) technology was established in 1990,
which used digital signals for transmission and two digital modulation schemes TDMA and CDMA
with circuit switched network . Second Generation uses the existing radio spectrum to provide the
services. It was developed to overcome the previous generation's drawbacks, and to have data and
voice transmission. But this generation also has few drawbacks like

Wimax vs. Long Term Evolution
Wimax vs. LTE:
LTE and Wimax are 4G technologies. LTE is Long Term Evolution project which is been proposed
by 3GPP (3rd generation partnership project) which is nothing but collaboration between various
telecommunication companies. So LTE has its background from the GSM technology. Wimax is
IEEE 802.16 standard and it's mainly roots in CDMA.
Frequency of operation: LTE operates at lower frequency as compared to wimax. Higher the
frequency of operation, higher the attenuation.
Both wimax and LTE uses OFDM (Orthogonal Frequency Division Multiplexing). OFDM uses
orthogonal frequencies as carrier frequencies so that there will be no interference between the
signals i.e. it uses the principle of orthogonality. This in turn improves the spectral efficiency.
Multiple Access: Both LTE and wimax uses MIMO (Multiple Input Multiple Output), which a
Space Division Multiple Access technique. It is a smart technique in which the same signal is
transmitted in different streams to the receiver. The receiver choses the best of the transmitted signal
streams and decodes the signal. It is chosen such a way that, the best quality signal is obtained. So,
even the weaker signals are boosted up by this technique.
Infrastructure: Both LTE and wimax uses ip infrastructure. The flat structure of ip helps the mobile
as well as the base station.
Latency: Latency is less in LTE when compared to wimax.
Range: Theoretically LTE has better rang than wimax.
Speed: speed of LTE is way higher than

3G (3rd generation mobile telecommunications)
3G wireless technology represents the convergence of various 2G wireless telecommunications
systems into a single global system that includes both terrestrial and satellite components. One of
the most important aspects of 3G wireless technology is its ability to unify existing cellular
standards, such as CDMA, GSM, and TDMA, under one umbrella. It improves the efficiency of data
can be transferred through the cellular phone. The data transfer rates for third generation mobile
telecommunications is up to 2 Megabits per second. Aside from this feature, 3G cellular phones also
have conventional voice, fax and data services, as well as high–resolution video and multimedia
services which can be used while on the move. It also includes mobile office services such as virtual
banking and online–billing, video conferencing, online entertainment and access to the Internet.

most common and most demanded device. This device not only used to communication but it also
supports data communication. Earlier there were different generations of mobiles which are used to
access the bet work. But the second generation mobile uses the GSM services and hence the GSM

combination of Time and FDM, the mobile is used to demultiplex the given channel and also it is
responsible for accessing the channel more effectively and efficiently. The mobile device is used to
transmit and receive the required data within in a given time frame and with if a give condition.

head of all industries due to the increasing in mobile usage day after day. It passed through several
generations until it reached this great evolvement which we see now. It started with the first
generation 1G with analog communication. In the second generation 2G the digital messaging was
added to the analog communication. In the 3G, both calls and messages became digital. In the 4G –
which we have now– the improvement was in the usage of a large bandwidth. The generation which
is expected to appear is the 5G. The 5G is purely based on the 4G and will give a huge level of
bandwidth which we cannot imagine. Furthermore, there are two predicted generations 6G and 7G.
The 6G will be a satellite based network with speed up to 1 GB. This leads to the space roaming

Abstract – Conventional wireless communication schemes use radio/micro wave frequencies for
data transmission, primarily because of the availability of high sensitivity receivers and ability to
provide broad coverage at low frequencies and line of sight communication at high frequencies. But,
RF can support only a limited bandwidth due to confined spectrum availability. Therefore the
expanding demand for wireless data has led to clogging of the radio spectrum. Thus there is a need
to study and use new communication technologies in near future that will reduce interference and
will be a clean source of communication. Communication is providing new advances constantly,
people are depending more and more on the benefits they provide.

Advantages And Disadvantages Of 4g Communication
INTRODUCTION :
Wireless communication is the transfer of information over a distance without the use of enhanced
electrical conductors or "wires". The distances involved may be short (a few meters as in television
remote control) or long (thousands or millions of kilometers for radio communications). When the
context is clear, the term is often shortened to "wireless". It encompasses various types of fixed,
mobile, and portable two–way radios, cellular telephones, Personal Digital Assistants (PDAs), and
wireless networking. 1895, Guglielmo Marconi opened the way for modern wireless
communications by transmitting the three–dot Morse code for the letter 'S' over a distance of three
kilometers using electromagnetic waves.

ABSTRACT
Mobile devices are getting smaller, lighter, and more powerful; they have bigger screens and longer
battery life, more features and more capabilities .With the rapid growth of user demands, and the
limitations of third generation (3G) mobile communication systems, it is expected that fourth
generation (4G) mobile systems are likely to reach the consumer market in another 4–5 years. 4G
systems are expected to become a platform capable of providing increased bandwidth, higher data
rates, and greater interoperability across communication protocols, and user friendly, innovative,
and secure applications. This system will primarily focus on seamlessly integrating the existing
systems like GSM, wireless LAN, and Bluetooth. Since 4G is ... Show more content on

Widespread deployment of WiFi is expected to start in 2005 for PCs, laptops and PDAs. In
enterprises, voice may start to be carried by Voice over Wireless LAN (VoWLAN). However, it is
not clear what the next successful technology will be. Reaching a consensus on a 200 Mbit/s (and
more) technology will be a lengthy task, with too many proprietary solutions on offer.
A third path is IEEE 802.16e and 802.20, which are simpler than 3G for the equivalent performance.
A core network evolution towards a broadband Next Generation Network (NGN) will facilitate the
introduction of new access network technologies through standard access gateways, based on ETSI–
TISPAN, ITU–T, 3GPP, China Communication Standards Association (CCSA) and other standards.
3. Key 4G Technologies
Some of the key technologies required for 4G are briefly described below:
3.1 OFDMA:
Orthogonal Frequency Division Multiplexing (OFDM) not only provides clear advantages for
physical layer performance, but also a framework for improving layer 2 performance by proposing
an additional degree of free– dom. Using ODFM, it is possible to exploit the time domain, the space
domain, the frequency domain and even the code domain to optimize radio channel usage. It ensures
very robust transmission in multi–path environments with reduced receiver complexity. As shown in
Figure 2 the signal is split into orthogonal subcarriers, on each of which the signal is "narrowband"
(a few kHz) and therefore immune to

Consumer Behaviour
A STUDY ON CONSUMER BUYING BEHAVIOUR OF MOBILE PHONES IN INDIA Synopsis
of Introduction Consumer behavior refers to the mental and emotional process and the observable
behavior of consumers during searching, purchasing and post consumption of a product or service.
Consumer behavior involves study of how people buy, what they buy, when they buy and why they
buy. It blends the elements from psychology, sociology, socio– psychology, anthropology and
economics. It also tries to assess the influence on the consumer from groups such as family, friends,
reference groups and society in general. Buyer behavior has two aspects: the final purchase activity
visible to any observer and the detailed or short ... Show more content on Helpwriting.net ...
Reference groups can be family, school or college, work group, club membership; citizenship etc.
Reference groups serve as one of the primary agents of consumer socialization and learning and can
be influential enough to induce not only socially acceptable consumer behavior but also socially
unacceptable and even personal destructive behavior. For example, if fresher student joins a college
/ university, he/she will meet different people and form a group, in that group there can be behavior
patterns of values, for example style of clothing, handsets which most of group member prefer or
even destructive behavior such as excessive consumption of alcohol, use of harmful and addictive
drugs etc. So, according to how an individual references him / herself to that particular reference
group, this will influence and change his/her buying behavior. Psychological Factors These are
internal to an individual and generate forces within that influence her/his purchase behavior. The
major forces include motives, perception, learning, attitude and personality. Example: Attitude is an
enduring organization of motivational, emotional, perceptual and cognitive processes with respect to
some aspect of our environment. Consumers form attitude towards a brand on the basis of their
beliefs about the brand. For example, consumers of Sony products might have the belief that the
products offered by Sony are durable; this will influence those customers to buy

Background In the past it was never clear that the cell phone would have such an important status in
today's society. But the development of the cell phone into a smartphone proves this statement right.
This includes transformations, besides the normal functionalities of a phone like text messaging,
receiving and making calls. A smartphone's operating system reflects the users lifestyle because it
controls the choice of applications, the general features and functionality in a phone. However the
mobile market is fragmented amongst the following software platforms or operating systems;
WebOS, BlackBerry OS, Windows phone formerly known as (Windows Mobile OS), Android OS,
Meego OS, Bada OS, Symbian OS, iPhone OS, and Tizen OS. Due to the continues advancement in
the technology of a smartphone, each smartphone needs an operating system in order for it to reach
its full capacity in today's world, however a phone is not smart on till it is powered by an operating
system. i.e. phone manufacturers such as Samsung, HTC, LG, SonyEricson etc. Play a role by
manufacturing a phone (hardware) with the demand and capability of running this software, which
is the OS inside. This simply means that the phone (hardware) is the infrastructure, while an

ABSTRACT
Mobile networks have made a remarkable growth in the last 20 years. In our time 4G is the main
network used to ensure IP connectivity for real time and non–real time services. It will be wrong not
to mention that in most 3rd world countries 3G and 2G networks are still of great importance in the
field of communication due to poor connectivity issues preventing them to utilize the services of 4G
services. This paper will mainly talk about the growth of mobile networks from say 3G to 4G and
also mention in details what we expect from 5G network. It will also mention some of the positive
and negative impacts to our Kenyan society and ways to ensure that we benefit fully from the
services. The proposal in this paper is fundamental shift in the mobile networking philosophy
compared to existing 3G and near–soon 4G mobile technologies, and this concept is called here –

It was commercially introduced in the Americas in 1978, Israel in 1986, and Australia in 1987.
AMPS was a pioneering technology that helped drive mass market usage of cellular technology, but
it had several serious issues by modern standards. It was unencrypted and easily vulnerable to
eavesdropping via a scanner; it was susceptible to cell phone "cloning;" Many of the iconic early
commercial cell phones such as the Motorola DynaTAC Analog AMPS were eventually superseded
by Digital AMPS (D–AMPS) in 1990, and AMPS service was shut down by most North American
carriers by 2008.
Digital cellular networks – 2G
In the 1990s, the 'second generation' mobile phone systems emerged. Two systems competed for
supremacy in the global market: the European developed GSM standard and the U.S. developed
CDMA standard. These differed from the previous generation by using digital instead of analog
transmission, and also fast out–of–band phone–to–network signaling. The rise in mobile phone
usage as a result of 2G was explosive and this era also saw the advent of prepaid mobile phones.
In 1991 the first GSM network (Radiolinja) launched in Finland. In general the frequencies used by
2G systems in Europe were higher than those in America, though with some overlap. For example,
the 900 MHz frequency range was used for both 1G and 2G systems in Europe, so the 1G systems
were rapidly closed down to make space for the 2G systems. In America the IS–54 standard was
deployed

Quality of Service Challenges In wireless networks, Quality of Service (QOS) refers to the
measure of the performance for a system reflecting its transmission quality and service availability
(e.g., 4G is expected to have at least a reliability of 99.99%). Supporting QOS in 4G networks will
be a major challenge. When considering QOS, the major hurdles to overcome in 4G include: varying
rate channel characteristics, bandwidth allocations, fault tolerance levels, and handoff support
among heterogeneous wireless networks. Fortunately, QOS support can occur at the packet,
transaction, circuit, and network levels. QOS will be able to be tweaked at these different operating
levels, making the network more flexible and possibly more tolerant to QOS issues. Varying rate
channel characteristics refers to the fact that 4G applications will have varying bandwidth and
transition rate requirements. In order to provide solid network access to support the anticipated 4G
applications, the 4G networks must be designed with both flexibility and scalability. Varying

The earliest systems were implemented based on analog technology and the basic cellular structure
of mobile communication. Many fundamental problems were solved by these early systems.
Numerous incompatible analog systems were placed in service around the world during the 1980s.
The 2G (second generation) systems designed in the 1980s were still used mainly for voice
applications but were based on digital technology, including digital signal processing techniques.
These 2G systems provided circuit‐switched data communication services at a low speed. The
competitive rush to design and implement digital systems led again to a variety of different and
incompatible standards such as GSM (global system mobile), TDMA (time division multiple
access); PDC (personal digital cellular) and CDMA (code division multiple access).These systems
operate nationwide or internationally and are todayʹs mainstream systems, although the data rate for
users in these system is very limited.

networks in contest of future of mobile communications. What are their drawbacks and what are the
main differences between these different generations along with the issues that make the new
network take over that network.
2– Background:
A look back in the history, the first generation of telephony (1G) started in the early of 1980s. This
network was designed to carry analog voice data. The (1G) networks were based on these standard
TACS, NMT, C–Nets and AMPS. In the early of 1990s the (2G) networks came as a digital network
comparing to the analog in (1G). That was the first digital cellular network after the switches that
were supported digital calls by using actual 0s and 1s. The (2G) networks were supported by these
standards D–AMPS, Code Division Multiple Access One (CDMAOne) and Global System of
Mobile Communication (GSM). The second generation of telephony (2G) was offered a higher
capacity, improved security and improved the voice quality. The (2G) technology was offered a
