EVOLUTION OF MOBILE
NETWORK FROM 1G TO 5G
First Generation wireless technology (1G) is the original
analog (An analog or analogue signalAn analog or analogue signal is any variable
signal continuous in both time and amplitude.), voice-only cellular telephone
standard, developed in the 1980s. The prominent ones among 1G system were
advanced mobile phone system (AMPS), Nordic mobile telephone (NMT), and total
access communication system (TACS). And it has no additional feauture

2 Based on analog system
3 Speed up to 2.4 kbps
2G-5G NETWORKS
The starting phase of the mobile networks are the analog
phones that has the capability to only supports voice telephony. After an interval
of 10 years in 1990 the second generation digital telephony comes into existence
during this period the telecom industry has a significant boom in terms of both
the subscriber and the value added services. Second generation of network
supports limited data support in the range of 9.6 kbps to 19.2 kbps. These network
use the circuit switching for voice
telephony. After this the development does not stop the 2g network are further
developed to 2.5g which uses circuit switching for voice and for data transmission
they use packet swithching. They are commonly called as GPRS OR Gernal packet
radio switching. In this the user
packet compete for bandwidth and user are gernally charged for data only
3g networks are also known as International mobile
telecommunication -2000 . IT is a generation of standard that fulfill the criteria specified by
international telecommunication union.With the development of the 3g networks the
problems that user faced in the 2g and
2.5 g networks, mainly the low speed and incompatible technologies like TDMA and CDMA . 3G has more bandwidth and
find
services in wireless voice telephony, mobile Internet access, fixed
wireless Internet access, video calls and mobile TV.
.There is also a concern that in many countries 3G will
never be deployed due to its cost and poor performance. Although it is possible
that some of the weaknesses at physical layer will still exist in 4G systems,
an integration of services at the upper layer is expected.
The development ion the mobile networks is mainly dependent
on the business challanges and the direction depends on the subscribers demands. It
is also effecte by the radio spectrum and the restrictions deployed over it by
the government. Hower as the major advancement are occurring in mobile networks
the standardization is becoming more and more complex . Many mobile system
standards are present there for large area network and are umts , cdma2000, hspa
etc. In addition there are evolving standards for Personal Area Networks
(PANs), such as Bluetooth wireless, and for WLANs, such as IEEE 802.11.
The current in mobile
system is to support the high bit data rate transfer at the downlink via hspda. It
provides a smooth advancement path for UMTS network to higher data rates in the
same way as the EDGE( ENHANCED DATA RATE FOR FOR GLOBAL EVOLUTION) do in GSM. ). HSPDA uses shared channels that
allow different users to access the channel resources in packet domain. It
provides an efficient means to share spectrum that provides support for high
data rate packet transport on the downlink, which is well adapted to urban
environment and indoor applications.
At the starting phase data rates of 10 mbps is achieved
using HSPDA but with the technical
advancements it has reached to 21.6 mbps and further can be increased to 30
mbps with the help of anteena array processing technologies followed by the
enhancements in air interface to aloow higher rates.
Another recent development is a new framework for mobile
networks that is expected to provide multimedia support for IP
telecommunication services, called as IP Multimedia Subsystems (IMS). Real-time
rich multimedia communication mixing telecommunication and data services couldhappendue
to IMS in wireline broadband networks. However, mobile carriers cannot offer
their customers the freedom to mix multimedia components (text, pictures,
audio, voice, video) within one call. Today a two party voice call cannot be
extended to a multi-party audio and video conference. IMS overcomes such
limitations and makes these scenarios possible.
The destinyof mobile
networks is mainly dependent upon the development and evolution of 4G
system , multimedia networking, and upto some extent, photonic network . It is
expected that at staring phase the 4G mobile systems will be used independently
from other presently used technologies. With gradual
development of high speed data support to multimegabits per second, athe integrations of present services will happen. In addition,
developments in photonic switching might allow mobile communication on a
completely photonic network using Wavelength Division Multiplexing (WDM) on
photonic switches and routers. The evolutionary view of 4G systems to 5G
include a support of wireless world wide web allowing a highly flexible and
reconfigurable dynamic adhoc networks.
TABULAR FORM OG THE EVOLUTION IS SHOWN BELOW
NETWORK ARCHITECTURE
The basic design of
wireless mobile system consist of a mobile phone connected to the wired world
via a single hop wireless connection to a Base Station (BS), which is
responsible for carrying the calls within its region called cell (Figure 1).
Due to limited coverage provided by a BS, the mobile hosts change their
connecting base stations as they move from one cell to another.
A handoff occur when the mobile user change its location
from one Base station to another base station. The mobile station communicate with
the BS by using multiplexing techiques also known as wireless
shairing techniques like FDMA, TDMA , CDMA etc.
Each Base station is connected to a Mobile Switching Center
(MSC) through fixed links, and each MSC is connected to others via Public
Switched Telephone Network (PSTN). The MSC is a local switching exchange that
handles switching of mobile user from one BS to another. It also locates the
current cell location of a mobile user via a Home Location Register (HLR) that
stores current location of each mobile that belongs to the MSC. In addition,
the MSC contains a Visitor Locations Register (VLR) with information of
visiting mobiles from other cells. The MSC is responsible for determining the current
location of a target mobile using HLR, VLR and by communicating with other
MSCs. The source MSC initiates a call setup message to MSC covering target area
for this purpose.
The first generation cellular implementation consisted of
analog systems in 450-900 MHz frequency range using frequency shift keying for
signaling and Frequency Division Multiple Access (FDMA) for spectrum sharing.
The second generation implementations consist of TDMA/CDMA implementations with
900, 1800 MHz frequencies. These systems are called GSM for Europe and IS-136
for US. The respective 2.5G implementations are called GPRS and CDPD followed
by 3G implementations.
Third generation mobile systems are intended to provide a
global mobility with wide range of services including voice calls, paging,
messaging, Internet and broadband data. IMT-2000 defines the standard
applicable for North America. In Europe, the equivalent UMTS standardization is
in progress. In 1998, a Third Generation Partnership Project (3GPP) was formed
to unify and continue the technical specification work. Later, the Third
Generation Partnership Project 2 (3GPP2) was formed for technical development
of CDMA-2000 technology.
3G mobile offers access to broadband multimedia services,
which is expected to become all IP based in future 4G systems. However, current
3G networks are not based on IP; rather they are an evolution from existing 2G
networks. Work is going on to provide 3G support and Quality of Service (QoS)
in IP and mobility protocols. The situation gets more complex when we consider
the WLAN research and when we expect it to become mobile. It is expected that
WLANs will be installed in trains, trucks, and buildings. In addition, it may
just be formed on an ad-hoc basis (like ad-hoc networks) between random
collections of devices that happen to come within radio range of one another
(Figure 2).
In general, 4G architecture includes three basic areas of
connectivity; PANs (such as Bluetooth), WANs (such as IEEE 802.11), and
cellular connectivity. Under this umbrella, 4G will provide a wide range of
mobile devices that support global roaming. Each device will be able to
interact with Internet-based information that will be modified on the fly for
the network being used by the device at that moment (Figure 3). In 5G mobile
IP, each cell phone is expected to have a permanent "home" IP
address, along with a "care-of" address that represents its actual
location. When a computer somewhere on the Internet needs to communicate with
the cell phone, it first sends a packet to the phone's home address.
Figure 3: Seamless Connection of Networks in 4G
A directory server on the home network forwards this to the
care-of address via a tunnel, as in regular mobile IP. However, the directory
server also sends a message to the computer informing it of the correct care-of
address, so future packets can be sent directly. This should enable TCP
sessions and HTTP downloads to be maintained as users move between different
types of networks. Because of the many addresses and the multiple layers of
subnetting, IPv6 is needed for this type of mobility.
For instance, 128 bits (4 times more than current 32 bit
IPv4 address) may be divided into four parts (I thru IV) for supporting
different functions. The first 32-bit part (I) may be defined as the home
address of a device while the second part (II) may be declared as the care-of
address allowing communication between cell phones and personal computers. So
once the communication path between cell and PC is established, care-of address
will be used instead of home address thus using the second part of IPv6
address.
The goal of 4G and 5G is to replace the current
proliferation of core mobile networks with a single worldwide core network
standard, based on IPv6 for control, video, packet data, and voice. This will
provide uniform video, voice, and data services to the mobile host, based
entirely on IPv6.
The objective is to
offer seamless multimedia services to users accessing an all IP-based infrastructure
through heterogeneous access technologies. IPv6 is assumed to act as an
adhesive for providing global connectivity and mobility among networks.
Figure 4: IPv6 address divided into four IPv4 addresses for
supporting 4G/5G functions.
Most of the wireless companies are looking forward to IPv6,
because they will be able to introduce new services. The Japanese government is
requiring all of Japan's ISPs to support IPv6 with its first 4G launch.
Although the US upgrade to IPv6 is less advanced, WLAN’s advancement may
provide a shortcut to 4G.

A new revolution of 5G technology is about to begin because
5G technology going to give tough completion to normal computer and laptops
whose marketplace value will be effected.
There are lots of improvements from 1G, 2G, 3G, and 4G to 5G
in the world of telecommunications. The new coming 5G technology is available
in the market in affordable rates, high peak future and much reliability than
its preceding technologies.
Features that are getting embedded in such a small piece of
electronics are huge. Today you will hardly witness a cell phone without an mp3
player with huge storage memory and a camera. You can use the cell phone as a
Walkman. Even every latest set being launched by the cell phone companies have
a mega pixel camera in it, which produces extraordinary digital image just like
a specialized camera for photography. Here are some an examples about mobile
technology in our future, A man’s phone detects that it hasn’t moved for more
than 2 hours during the man’s regular waking hours. It issues an audible alarm,
but no response! So it emits a signal that triggers a RFID chip implanted
inside his body. The RFID chip responds by verifying the identity of the man
and also a brief burst of telemetry that indicates that he is experiencing
heart beat irregularities and his blood pressure is dangerously low. The phone
quickly sends an automated text message to a medical alarm system, including
not only the identity and the health data of the owner but also the fact that
the man is not in his own apartment but in a reading room of a library.
This is what I think of a “Fifth Generation” world, also
sometimes referred as the 5G world. The next logical step is to bring
high¬speed broadband to police cars and other emergency vehicles," stated
Brian Corty, Chief Technology Officer for 5G Wireless Communications. "We
believe our solution is capable of bringing high¬speed connectivity to these
vehicles at a relatively low cost." "We're really taking 802.11b
technology to new heights and new applications," stated Jerry Dix,
President and CEO of 5G Wireless. "We're in the field testing, mapping and
demonstrating speeds upward of 1 Mbps, while traveling at 35 MPH and we are in
the process of proving that the vehicle units would remain connected as they
move between multiple 5G Access Points for seamless roaming capabilities."
The Mobile Wi-Fi capability is an extension of 5G's recently
announced WiFi Hot Zone. Whereas local hot spot "only reach an area of 300
ft. from an access point, 5G's enhanced package provides coverage over a mile
away. Augmented by strategically
placed "repeaters," it is possible to provide the entire fleet of
police cars and emergency vehicles total coverage within the 7-square-mile city
limits. The 5G technology has been able to penetrate both manmade and natural
obstacles while delivering speeds consistent with line-of-sight
locations. This enables the company to provide innovative wireless solutions in
response to increased national security and emergency management concerns.
Having a wireless infrastructure is critical to our Public
Safety operations, We now have a reliable means of providing critical
information as well as normal municipal functions in the event of an emergency.
And it's gratifying to know we're doing it at an affordable level at a time
when we are under intense pressure to reduce costs due to the State's budget crisis."

FUNCTIONAL ARCHITECTURE
Below figure shows the system model that proposes design of
network architecture for 5G mobile systems, which is all-IP based model for
wireless and mobile networks interoperability. The system consists of a user
terminal (which has a crucial role in the new architecture) and a number of
independent, autonomous radio access technologies. Within each of the
terminals, each of the radio access technologies is seen as the IP link to the
outside Internet world. However, there should be different radio interface for
each Radio Access Technology (RAT) in the mobile terminal. For an example, if
we want to have access to four different RATs, we need to have four different
access - specific interfaces in the mobile terminal, and to have all of them
active at the same time, with aim to have this architecture to be functional
applications and servers somewhere on the Internet. Routing of packets should
be carried out in accordance with established policies of the user.
HARDWARE OF 5G
It uses UWB (Ultra Wide Band) networks with higher BW at
low energy levels.
