INTRODUCTION
• What is 5G technology?
• 5G Technology stands for 5th Generation Mobile technology. 5G
mobile technology has changed the means to use cell phones within
very high bandwidth. User never experienced ever before such a high
value technology. Nowadays mobile users have much awareness of the
cell phone (mobile) technology. The 5G technologies include all type
of advanced features which makes 5G mobile technology most
powerful and in huge demand in near future.

GENERATIONS OF MOBILE
NETWORK 1G :
system (NMT) was introduced in 1981, It support
speed up to 2.4kbps. Major contributors were
AMPS, NMT, and TACS.
It has low capacity, unreliable handoff, poor voice
links, and no security at all since voice calls were
played back in radio towers, making these calls
susceptible to unwanted eavesdropping by third
parties.

NETWORK 2G :
 The second generation of digital mobile phones
appeared in 1990s along with the first digital
mobile networks
 Mainly used for Voice communication and
supports speed up to 64kbps
 Offered additional services such as SMS and e-
mail
 Major prominent technologies were

NETWORK
2.5G :
 General Packet Radio Service (GPRS), are an
extension of 2G networks
 they use circuit switching for voice and packet
switching for data transmission
 The first full internet service on mobile phones
was introduced by NTT DoCoMo in Japan in
1999

NETWORK 3G :
 NTT DoCoMo launched the first commercial 3G
network on 1 October 2001, using the WCDMA
technology
 bandwidth of 3G network is 128 Kbps for mobile
stations, and 2 Mbps for fixed applications
 The current trend in mobile systems is to support
the high bit rate data services at the downlink via
High Speed Downlink Packet Access (HSDPA)

NETWORK provides a smooth evolutionary path for UMTS networks
to higher data rates in the same way as Enhanced Data
rates for Global Evolution (EDGE) do in Global Systems
for Mobile communication (GSM)
 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
 Initially, the peak data rates of 10 Mbps may be
achieved using HSPDA. The next target is to reach 30
Mbps with the help of antenna array processing
technologies followed by the enhancements in air
interface design to allow even higher data rates

NETWORK 4G :
 launched in November 2011
 Use of a higher Layer Protocol (IP) as transport
medium affords intelligence at every stage within the
network relative to a service
 Airtel is using the TD-LTE (Time-Division Long-Term
Evolution), which is a variant of LTE developed by
China, to provide its 4G services

NETWORK
 4G features: next generation of wireless
applications and services, such as e-
readers, mobile IPTV, mobile marketing and geo-
targeted advertising, location-based mobile
applications embedded in social networking are
likely to become the key applications in the
upcoming 4G apps space

NETWORK ARCHITECTURE
 The basic architecture of wireless mobile system
consists 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
 The mobile station communicates via the BS using
one of the wireless frequency sharing technologies
such as FDMA, TDMA, CDMA etc. Each BS is
connected to a Mobile Switching Center (MSC)
through fixed links, and each MSC is connected to
others via Public Switched Telephone Network

 MSC also locates the current cell location of a
mobile user via a Home Location Register (HLR) that
stores current location of each mobile
 the MSC contains a Visitor Locations Register
(VLR) with information of visiting mobiles from other
cells
 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

MOBILE SYSTEM/WLAN
INTEGRATION

 The second generation implementations consist of
TDMA/CDMA implementations with 900, 1800 MHz
frequencies
 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
 3G mobile offers access to broadband multimedia
services, which is expected to become all IP based in
future 4G systems
Conti…

 4G architecture includes three basic areas of
connectivity; PANs (such as Bluetooth), WANs
and cellular connectivity
 4G will provide a wide range of mobile devices
that support global roaming
 4G architecture is designed to optimize
network performance, improve cost efficiency
and facilitate the uptake of mass market IP-
based services

 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
 IPv6 is needed for many addresses and the multiple
layers of subnetting
 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

COMPARISON OF 1G-5G TECHNOLOGIES

 The third part (III) of IPv6 address may be
used for tunneling to establish a connection
between wire line and wireless network. In this
case an agent (a directory server) will use the
mobile IP address to establish a channel to cell
phones
 The fourth and last part (IV) of IPv6 address
may be used for local address for VPN sharing.
Figure 4 illustrates the concept

KEY CONCEPTS OF 5G
 Real wireless world with no more limitation with
access and zone issues
 Internet protocol version 6 (IPv6), where a visiting care-
of mobile IP address is assigned according to
location and connected network
 One unified global standard
Additional features such as Multi-Media
Newspapers, also to watch T.V programs with the
clarity as to that of an HD T.V

KEY CONCEPTS OF 5G
 We can send Data much faster that that of
the previous generations
 5G will bring almost perfect real world
wireless or called “WWWW: World Wide
Wireless Web

FEATURES OF 5G NETWORKS
TECHNOLOGY 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
 high quality services of 5G technology based on
Policy to avoid error
 traffic statistics by 5G technology makes it more
accurate

FEATURES OF 5G NETWORKS
TECHNOLOGY
 5G technology offer transporter class gateway with
unparalleled consistency
 Through remote management offered by 5G
technology a user can get better and fast solution
 The 5G technology also support virtual private
network
 The uploading and downloading speed of 5G
technology touching the peak
 5G technology will take all delivery service out of
business prospect

CONCLUSION
 The current and future trends in mobile systems
is considered that includes the evolutionary path
starting from first generation mobile phone
systems and is continuing to the development of
5th generation systems
 There are some other projects, which are
undertaken by 5G technologies. Here we want to
mention that 4G mobiles are working these days
in some countries, and 5G technologies are
coming in future

CONCLUSION
 It is very interesting that all the nearby
countries are locally connected in 5G
Network that is if you like to call in Pakistan
or China from India, this call should be local
rates, it is not consider as ISD calls
