Abstract — The wireless industry is busy with standardization of
fourth generation cellular networks. The 4G standards are expected
to be concluded in the next year or two. 4G wireless system cannot
exist in today’s market without standardization. The 4G concept
already moved to the standardization phase, we must begin to work
on building blocks of the 5G wireless networks. The major difference,
from a user point of view, between current generations and expected
5G techniques must be something else than increased maximum
throughput; other requirements include low battery consumption,
more secure. We refer to this goal as enabling the 4A’s paradigm i.e.
Any rate, Anytime, Anywhere and Affordable. In particular, this paper
focuses on the features such as broadband internet in mobile phones
with a possibility to provide internet facility in the computer by just
connecting the mobile and with a speed of 10Gbps and more. In 5G
researches are being made on development of World Wide Wireless
Web (WWWW), Dynamic Adhoc Wireless Networks (DAWN) and
Real Wireless World.
Keywords—1G, 2G, 3G, 4G, 5G, GSM
INTRODUCTION
We are living in modern science. We cannot think a
single moment without science. Science makes our life easy
and comfortable. Modern world is being compressed due to
the development of science and its technologies. During the
last few decades, the world has seen phenomenal changes in
the telecommunications industry due to science and
technology. We have different mobile and wireless
communication technologies, which are mass deployed, such
as WiMAX, Wi-Fi, LTE (Long Term Evolution), 3G mobile
networks (UMTS, cdma2000) and 4G as well as
accompanying networks, such as personal area networks (e.g.,
Bluetooth, ZigBee) or sensor networks. Mobile terminals
include variety of interfaces, such as GSM is one, which are
based on old-fashioned circuit switching, the technology that
is going into its last decade of existence. These technologies
(mainly cellular generations) differ from each other based on
four main aspects: radio access, data rates, bandwidth and
switching schemes . These differences have been noticed in
previous generations (1G, 2G, 2.5G and 3G etc.). In
accordance to, we are exploring the most advance cellular
technology, could be 5G.
5G Technology stands for 5th Generation Mobile
Technology. 5G technology has changed to use cell phones
within very high bandwidth. 5G is a packet switched wireless
system with wide area coverage and high throughput. 5G
technologies use CDMA and BDMA and millimeter wireless
that enables seed is greater than 100Mbps at full mobility and
higher than1Gbps at low mobility. The 5G technologies
include all types of advanced features which make 5G
technology most powerful and in huge demand in the near
future. It is not amazing, such a huge collection of technology
being integrated into a small device. The 5G technology
provides the mobile phone users more features and efficiency.
A user of mobile phone can easily hook their 5G technology
gadget with laptops or tablets to acquire broadband internet
connectivity. Up till now following features of the 5G
technology have come to surface- High resolution is offered
by 5G for extreme mobile users, it also offers bidirectional
huge bandwidth , higher data rates and the finest Quality of
Service (QoS).
EVOLUTION FROM 0G TO 5G
Classical 0G
Wireless telephone started with what you might call 0G. the
great ancestor is the mobile telephone service that became
available just after World War II. Technologies use in 0G
systems included PTT (Push To Talk), MTS (Mobile Telephone
System), IMTS (Improved Mobile Telephone Service), AMTS
(Advanced Mobile Telephone System).
1G:GSM
0G vision proved wrong when the GSM concretely came to
life in 1990-91 in Finland.1G was old analog system and
supported the 1st generation of analog cell phones speed up to
2.4kbps. Advance mobile phone system (AMPS) was first
launched by the US and is a 1G mobile system. It allows users
to make voice calls in one country.
Fig.1: 1G Mobile Phone
1G technology replaced 0G technology, which featured mobile
radio telephones and such technologies as Mobile Telephone
System (MTS), Advanced Mobile Telephone System (AMTS),
Improved Mobile Telephone Service (IMTS), and Push to Talk
(PTT).

2. 2G
2G cellular telecom networks were commercially launched
on the GSM standard in Finland by Radio linja in 1991. 2G
technologies enabled the various mobile phone networks to
provide the services such as text messages, picture messages
and MMS (multimedia messages). 2G technology is more
efficient.. It was planned for voice transmission with digital
signal and the speeds up to 64kbps.2G technology holds
sufficient security for both the sender and the receiver. All text
messages are digitally encrypted. This digital encryption
allows for the transfer of data in such a way that only the
intended receiver can receive and read it. Second generation
technologies are either time division multiple access (TDMA)
or code division multiple access (CDMA). TDMA allows for
the division of signal into time slots. CDMA allocates each
user a special code to communicate over a multiplex physical
channel. Different TDMA technologies are GSM, PDC, iDEN,
I.S-136. CDMA technology is IS-95.
GSM has its origin from the Group Special Mobile, in
Europe. GSM is also stands for Global System for mobile
communication. Now GSM is used in more than 212 countries
in the world. GSM technology was the first one to help
establish international roaming. In comparison to 1G's analog
signals, 2G's digital signals are very reliant on location and
proximity.
Fig.2: 2G Mobile Phone
2.75G:EDGE
Which is a pretty recent standard allows for downloading
faster. Since mobile devices have become both a TV and a
Walkman or music player, people needed to be able to watch
streaming video and download mp3 files faster that´s precisely
what EDGE allows for and that’s for the good news. The bad
news is that if EDGE rock sat downloading, it´s protocol is a
symmetrical hence making EDGE suck at uploading i.e.
broadcasting videos of yours for instance. Still an interesting
achievement thanks to which data packets can effectively
reach 180 Kbytes/sec. EDGE is now widely being used.
3G:UMTS
Third generation (3G) services combine high speed mobile
access with Internet Protocol (IP)-based services. The main
features of 3G technology include wireless web base access,
multimedia services, email, and video conferencing. The 3G
W-CDMA air interface standard had been designed for
―always-on‖ packet-based wireless service, so that computer,
entertainment devices and telephones may all share the same
wireless network and be connected internet anytime,
anywhere. 3G systems offer high data rates up to 2 Mbps, over
5 MHz channel carrier width, depending on mobility/velocity,
and high spectrum efficiency. The data rate supported by 3G
networks depends also on the environment the call is being
made in; 144 kbps in satellite and rural outdoor, 384 kbps in
urban outdoor and 2Mbps in indoor and low range outdoor.
The frequency band is 1.8 - 2.5 GHz.
Fig.3: 3G Mobile Phone
3.5G:HSDPA
It is theoretically six times faster than UMTS. Practically
speaking this would mean, downloading a mp3 file would take
about 30 seconds instead of something like 2 minutes.
4G
The basic feature of 3G Technology is fast data transfer
rates. However this feature is not currently working properly
because, ITU 200 is still making decision to fix the data rates.
Network authentication has won the trust of users, because the
user can rely on its network as a reliable source of transferring
data. . 4G is a conceptual framework and a discussion point to
address future needs of a high speed wireless network. It is
expected to emerge around 2010 – 2015. 4G should be able to
provided very smooth global roaming ubiquitously with lower
cost.
Some of the applications are:
1. Mobile TV – a provider redirects a TV channel directly to
the subscriber's phone where it can be watched.
2. Video on demand – a provider sends a movie to the
subscriber's phone.
3. Video conferencing – subscribers can see as well as talk to

3. each other.
4. Location-based services – a provider sends localized
weather or traffic conditions to the phone, or the phone allows
the subscriber to find nearby businesses or friends
5. Mobile ultra-broadband (gigabit speed) access and multi-
carrier transmission.
6. Mobile WiMAX (Worldwide Interoperability for
Microwave Access)

5G
5G Wireless Communication System is not deployed yet.
The big challenge for the design and deployment of 5G
wireless system can be faced easily as proposed features and
architecture (mentioned below) that will increase system
capacity and quality within the limited available frequency
spectrum, whose frequency band and Data Bandwidth will be
‗3-300GHz‘ and ‗1Gbps & higher (as demand)‘ successively.
The remarkable issue, there don‘t have any limitation in 5G as
respect to user demands in the next 200 years. The 5G also
implies the whole wireless world interconnection (WISDOM
—Wireless Innovative System for Dynamic Operating Mega
communications concept), together with very high data rates
of the Quality of Service (QoS) applications.

techniques must be something else than increased maximum
throughput. 5G is to be a new technology that will provide all
the possible applications, by using only one universal device,
and interconnecting most of the already existing
communication infrastructures. The 5G terminals will be an
upgradable multimode and cognitive radio- enabled. It will
have software defined radio modulation schemes. All the
required upgradable software should be downloaded from the
Internet on the run. The 5G mobile networks will focus on the
