Abstract:
Commercial cellular wireless communications have a history of about 3 decades. Currently, the wireless industry is busy with the
standardization of the 4th generation (4G) cellular networks, namely, LTE/LTE- Advanced and WIMAX 802.16m. The 4G standards are
expected to be concluded in the next year or two. The early commercial deployments could initiate in subsequent years. With 4G networks,
wireless internet connectivity will be faster and more affordable which will result in substantial increase in wireless internet usage. Since the
4G concepts have already moved to the standardization phase, we must begin to work on the building blocks of the next generation (which we
refer to as 5G) wireless networks. These networks will facilitate the provision of omnipresent and affordable broadband with very high speed
wireless connectivity. This paper aims at highlighting some of the key concepts and technologies which will facilitate the affordable provision
of very high data rates with virtually ubiquitous coverage in 5G wireless networks. 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. Techniques with
certain advanced physical layer operations in the presence of advanced radio access network (RAN) architectures, we refer to this design
principle as the “integrated cross-layer cross-network design”.
INTRODUCTION
Classical 0G phones stood for the first generation of
mobile phones i.e. Satellite phones developed for boats
mainly. Networks such as Iridium, Global Star and
Eutelsat were truly worldwide (although for physical
reasons, think of a satellite as a fixed point above the
equator, some Northern parts of Scandinavia aren‟t
reachable), and everybody thought at that time that
satellite phones would become mainstream products as
soon as devices got smaller and cheaper. This vision
proved wrong when the GSM concretely came to life in
1990-91 in Finland.
1G: Firstly, there were analog GSM systems that existed
for a few years. And then came the digital systems.
2G: the second generation of mobile
telecommunications still is the most widespread
technology in the world; you‟ve basically all heard of the
GSM norm (GSM stands for Groupe Spécial Mobile in
French, renamed in Global System for Mobility). The
GSM operates in the 850Mhz. and 1900Mhz. bands in
the US, & 900Mhz. and 1.8Mhz. bands in the rest of the
world (eg did you know Bluetooth stands in the 2.4Ghz.
area, just like your…microwave!? But that‟s another
story, not related to this article) and delivers data at the
slow rate of 9.6 Kbytes/sec.
2.5G: For that last reason (9.6 Kbytes/sec doesn‟t allow
you to browse the Net or up/download an image), telco operators came up with the GPRS (remember all the hype
around the Wap) which could enable much faster
communications (115Kbytes.sec). But the market decided it
was still not enough compared to what they had at home.
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 rocks at downloading, it‟s protocol is
asymmetrical hence making EDGE suck at uploading ie
broadcasting videos of yours for instance. Still an
interesting achievement thanks to which data packets can
effectively reach 180kbytes/sec. EDGE is now widely
being used.
3G: also called UMTS (Universal Mobile
Telecommunications Standard). Aimed at enabling long
expected videoconferencing, although nobody seems to
actually use it (do you know any?). Its other name is
3GSM, which says literally that UMTS is 3 times better
than GSM. One issue though: depending on the
deployment level of the area you are in and your device,
your phone will (have to be) handle(d) from the GSM
network to the UMTS network, and conversely – making
billing more complex to understand for the consumers.
One of the major positive points of UMTS is its global
roaming capabilities (roaming is the process that allows
you, at a cost, to borrow bandwidth from a telco provider
that‟s not yours; you usually use roaming when calling
from abroad).
4G: still a research lab standard, at least to my
knowledge, that should combine the best of cell phone
network technologies with WiMax wireless Internet,
voice over IP and IPv6 (a post about the latter soon).
Data rates are expected to reach 100 Mbytes/sec[1].
After the launch of 4G technology in some countries
like Unites States of America and United Kingdom,
research has started towards the next generation of
mobiles that is the fifth generation. The name 5G has not
been used by any standardization bodies or any company
in telecom sector since 4G standards haven‟t been
standardized fully. After studying the increase in data
rates from generation to generation, one can roughly
predict that maximum data rates i.e. uploading or
downloading rates in 5G would be 10 Gbps. This
generation is expected to be rolled out in 2012-13 .
5G : 5th generation mobile networks or 5th generation
wireless systems is a name used in some research papers
and projects to denote the next major phase of mobile
telecommunication standards beyond the upcoming 4G
standards (which is expected to be finalized between
approximately 2011 and 2013)[4].
5G offers Peak per terminal throughput – 10 Gbps
outdoors, spectral efficiency. – 5 bps/Hz/cell, areal
reliability – 99.5%, round trip delay < 1 ms,
seamless coexistence with other radios. These goals are
significantly ahead of 4G performance. The new tools
that can take us these goals may include Opportunistic
OFDMA, 20-60 MHz channel bandwidth, cognitive and
opportunistic channel structure, flexible ,variable reuse,
cooperative methods, interference management, client
relay, hierarchical modulation, distributed MIMO and
WHAT IS 5G NETWORK?
5G network is very fast and reliable. The concept of
handheld devices is going to be revolutionized with the
advent of 5G. Now all the services and applications are going
to be accessed by single IP as telephony, gaming and many
other multimedia applications [5]. As it is not a new thing or
gadget in market and there are millions of users all over the
world who have experienced the wireless services and till
now they are obsessed to this wireless technology. It is not
easy for them to shrink from using this new 5G network
technology. There is only need to make it accessible so that a
common man can easily afford the profitable packs offered
by the companies so that 5G network could hold the
authentic place. There is need to win the customer trust to
build fair long term relation to make a reliable position in the
telecommunication field. To compete with the preceding
wireless technologies in the market 5G network has to tender
something reliable something more pioneering. All the
features like telephony, camera, mp3 player, are coming in
new mobile phone models. 4G is providing all these utility in
mobile phone. By seeing the features of 4G one can gets a
rough idea about what 5G Network could offer. There is
messenger, photo gallery, and multimedia applications that
are also going to be the part of 5G. There would be no
difference between a PC and a mobile phone rather both
would act vice versa. 5G technology going to be a new
mobile revolution in mobile market. Through 5G technology
now you can use worldwide cellular phones and this
technology also strike the china mobile market and a user
being proficient to get access to Germany phone as a local
phone. With the coming out of cell phone alike to PDA now
your whole office in your finger tips or in your phone. 5G
technology has extraordinary data capabilities and has ability
to tie together unrestricted call volumes and infinite data
broadcast within latest mobile operating system. 5G
technology has a bright future because it can handle best
technologies and offer priceless handset to their customers.
May be in coming days 5G technology takes over the world
market. 5G Technologies have an extraordinary capability to
support Software and Consultancy. The Router and switch
technology used in 5G network providing high connectivity.
The 5G technology distributes internet access to nodes within
the building and can be deployed with union of wired or
wireless network connections. The current trend of 5G
technology has a glowing future [6]
Features of 5G
According to some research papers on 5G technology, the
main features the technology might have are as follows:
A 5G user might be able to connect to different networks
at same time or switch between two networks. These
networks need not be 5G networks but they can be of
any generation.
Introduction of a new radio system is possible in which
different radio technologies will share the same
spectrum. This can be done by finding unused spectrum
and then adapting to the technology of the radio
technology with which the spectrum is being shared.
Every mobile in a 5G network will have an IP address
(IPV6) according to the location and network being
used.
5G technology is expected to bring a single global
standard.
The technology is also expected to support virtual
private networks and advanced billing interfaces.
With 5G enabled phone, you might be able to connect
your phone to your laptop to get access to broadband.
The other few features that might be offered by 5G are
transporter class gateway , subscriber supervision tools ,
remote diagnostics etc.
5G technology offer high resolution for crazy cell phone
user and bi-directional large bandwidth shaping.
The advanced billing interfaces of 5G technology makes
it more attractive and effective.
5G technology also providing subscriber supervision
tools for fast action.
The high quality services of 5G technology based on
Policy to avoid error.
5G technology is providing large broadcasting of data in
Gigabit which supporting almost 65,000 connections.
5G technology offer transporter class gateway with
unparalleled consistency
The traffic statistics by 5G technology makes it more
accurate.
Through remote management offered by 5G technology
a user can get better and fast solution.
The remote diagnostics also a great feature of 5G
technology.
The 5G technology is providing up to 25 Mbps
connectivity speed.
The 5G technology also support virtual private network.

th
GENERATION TECHNOLGY ARCHITECTURE
A first remarkable feature of 5G network is the broadband
internet in mobile phones that would be possible to provide
internet facility in the computer by just connecting the
mobile as depicted in figure 3.
Handheld Computer: Data sharing in 5G network is very
easy. It omits the condition of putting both mobile face to
face so that data could be shared. But 5G Bluetooth
technology removes this condition and data could be
transferred if it is shared in the range of 50m [2]. It is not far
away when we see the global mobiles all over the world. A
user can move everywhere in the world by holding just 5G
mobile network. All the roaming would be exempt from the
tariff plans. The rates of the call would not be different area
to area.
CONCLUSION
Nowadays, wireless technology is getting popular and
important in the network and the Internet field. In this paper,
we briefly introduced the history background of 1G to 5G,
compared the differences of 3G and 4G, and illustrated how
4G may work for more convenient and powerful in the
future. 4G just right started from 2002 and there are many
standards and technologies, which are still in developing
process. Therefore, no one can really sure what the future 4G
will look like and what services it will offer to people.
However, we can get the general idea about 4G from
academic research; 4G is the evolution based on 3G‟s
limitations and it will fulfill the idea of WW, World
Wide Wireless Web, offering more services and smooth
global roaming with inexpensive cost. A new
revolution of 5G technology is about to begin because 5G
technology is going to give tough competition to normal
computer and laptops. There are lots of improvements from
1G, 2G, 3G, and 4G to 5G in the world of
telecommunications. The novel impending 5G technology is
available in the market in affordable rates, high peak future
and much reliability than its preceding technologies.
