In this presentation we will discuss 5G wireless systems,
better known as 5th generation mobile technology.
Mobile wireless industry had started its technology creation,
revolution and evolution since early 1970’s.
5G wireless technology can change the way we use wireless
gadgets by providing very high bandwidth.
The 5G should be featured with intelligent technology that
interconnects the entire world without limits.
5G introduces a whole new concept of multi-path data path
scheme for a real wireless world, a complete wwww.
Thus, 5G should add a number of added advantages over
the present 4G technology.
1G: were designed to offer a single service, i.e., speech.
2G:were also designed primarily to offer speech with a
limited capability to offer data at low rates.
3G:are expected to offer high-quality multi-media services
and operate in different environments.
4G:dynamic information access ,variable devices.
At the end of the 1940’s, the first radio telephone
service was introduced, and was designed to users in
cars to the public land-line based telephone network.
In the 1960’s, a system launched by Bell Systems,
called, Improved Mobile Telephone Service (IMTS),
brought quite a few improvements such as direct dialing
and more bandwidth. The very first analog systems were
based upon IMTS and were created in the late 60s and
1G was an analogue system, and was
developed in the 70’s. 1G had two major improvements, this
was the invention of the micro-processor, and the digital
transform of the control link b/w the phone and the cell site.
AMPS was 1st
launched by the us and
is a 1G mobile system based on FDMA, it allows users to
make voice calls in country.
2G devices using GSM were 1st
used early of 90’s
in Europe. GSM provides voice and limited data service , and uses
digital modulation for improved audio quality. The development of 2G
cellular system was driven by the need to improve
2G uses the standards such as
3G technology adds multimedia facilities to 2G devices by allowing
video, audio, and graphics applications over 3G devices. You can
watch streaming video or have video telephony
3G networks provide the ability to transfer voice data and non-
voice data over the same network simultaneously
3G networks deliver broadband capacity and support greater
numbers of voice and data customers at lower incremental costs than
- W-CDMA: Wideband Code Division Multiple Access
- EVDO: Evolution-Data Optimized
4G technology refer to or short name of fourth Generation
which was started from late 2000s.
Capable of providing 100Mbps – 1Gbps speed.
One of the basic term used to describe 4G is MAGIC.
» Mobile Multimedia
» Anytime Anywhere
» Global Mobility Support
» Integrated Wireless Solution
» Customized Personal Services
» Also known as Mobile Broadband Everywhere.
High network capacity: more simultaneous users per cell
A data rate of at least 100 Mbit/s between any two points in the world
Seamless connectivity and global roaming across multiple networks
>WiMAX (IEEE 802.16e)
FDMA – Frequency Division Multiple Access
Each phone call is allocated one frequency for the entire
duration of the call
TDMA - Time Division Multiple Access
Each phone call is allocated a spot in the frequency for a
small amount of time, and "takes turns" being transmitted
CDMA –Code Division Multiple Access
Form of multiplexing
Does not divide up the channel by time or frequency
Encodes data with a special code associated with each
Long Term Evolution (LTE) is a radio platform technology that
will allow operators to achieve even higher peak throughputs than
HSPA+ in higher spectrum bandwidth.
The overall objective for LTE is to provide an extremely high
performance radio-access technology that offers full vehicular speed
mobility and that can readily coexist with HSPA and earlier
networks. Because of scalable bandwidth, operators will be able to
easily migrate their networks and users from HSPA to LTE over
LTE assumes a full Internet Protocol (IP) network architecture
and is designed to support voice in the packet domain.
Is a wireless communication standard designed to
provide 30 to 40Mbps data rates. With the 2011 update
providing up to 1Gbps for fixed stations.
The name wimax was created by the wimax forum,
which was formed in June 2001 to promote conformity
and interoperability of the standard
The forum describes wimax as a standard –based
technology enabling the delivery of last mile wireless
broadband access as an alternative to cable and DSL
World Interoperability for Microwave Access
There are two main applications of WiMAX:
– Fixed WiMAX (IEEE 802.16-2004) - Fixed WiMAX
applications are point-to-multipoint enabling the delivery of last
mile wireless broadband access as an alternative to cable and
DSL for homes and businesses.
– Mobile WiMAX (IEEE 802.16e-2005) - Mobile WiMAX
offers the full mobility of cellular networks at true broadband
Poor voice quality
Poor battery life of devices
Large device size
Frequent call drops
Limited n/w capacity
Poor hand off reliability
The GSM is circuit switched, circuit oriented technology,
where the end systems are dedicated for entire call session.
This causes inefficiency in usage of band width and
The GSM enabled systems do not support high data rates
They are unable to handle complex data such as video
Difficulty of CDMA to provide higher data rates
Need for continuously increasing data rate and
bandwidth to meet the multimedia requirements
Limitation of spectrum and it’s allocation
Inability to roam between different services
To provide a seamless transport end-to-end
>Battery uses is more
>Hard to implement
>Need complicated hardware
>Expensive equipment required
to implement next generation
WHY 5G IS REQUIRED
>These factors are enough to cause a substantial bottle neck in cellular
>Through the projected data rate around 100Mbps in 4G.Actual data rate
>Data service like multimedia are going to play modest role and will
dominate the cellular traffic instead of voice in future in such
scenario the present 2G and 3G system will saturated and will have no
room to survive.
>Demand for increasing data rate leads to higher band width
WHAT IS 5G...?
5G (5th generation mobile networks or
5th generation wireless systems) denotes
the next major phase of mobile
telecommunications standards beyond the
current 4G/IMT-Advanced standards. 5G
is also referred to as beyond 2020 mobile
5G networks are projected to provide
speeds above 1 Gbps.
>5G envisions to design a real wireless world, that is free from
obstacles of the earlier generations.
>This requires an integration of networks.
>5G aims to design a Multi-Bandwidth Data Path by integrating
the current and future networks for new network architecture
of 5G real wireless world.
Vision of 5G
Key Concepts of 5G
Real wireless world with no more limitation with
access and zone issues.
Wearable devices with AI capabilities.
Internet protocol version 6(IPv6).
One unified global standard.
The 5G terminals will have software
defined radios and modulation schemes as well as new error-control
schemes that can be downloaded from the Internet. The development is
seen towards the user terminals as a focus of the 5G mobile networks.
The terminals will have access to different wireless technologies at the
same time and the terminal should be able to combine different flows
from different technologies.
Basic Architecture of 5G
PHYSICAL LAYER :
Physical and Medium Access Control layers i.e. OSI layer 1 and OSI
layer 2, define the wireless technology. For these two layers the 5G
mobile networks is likely to be based on Open Wireless
All mobile networks will use mobile IP
Each mobile terminal will be FA (Foreign Agent)
A mobile can be attached to several mobiles or wireless
networks at the same time
Separation of network layer into two sub-layers:
(i) Lower network layer (for each interface)
(ii) Upper network layer (for the mobile terminal)
Wireless network differs from wired network regarding the
In all TCP versions the assumption is that lost segments are
due to network congestion
5G mobile terminals have transport layer that is possible to be
downloaded & installed – Open Transport Protocol (OTP)
Open Transport Protocol (OTP):
Application (service) Layer:
Provides Quality of Service (QoS)
QoS parameters, such as, delay, losses, BW, reliability, will be
stored in DB of 5G mobile
Presentation layer + Application layer = Application
Where we are.......
On 12 May 2013, Samsung Electronics stated that they have developed the
world's first "5G" system. The core technology has a maximum speed of tens
of Gbit/s (gigabits per second). In testing, the transfer speeds for the “5G”
network sent data at 1.056 Gbit/s to a distance of up to 2 kilometres.with the
use of an 8*8 MIMO
In July 2013, India and Israel have agreed to work jointly on development of
fifth generation (5G) telecom technologies.
On 1 October 2013, NTT (Nippon Telegraph and Telephone), the same
company to launch world first 5G network in Japan,
On 6 November 2013, Huawei announced plans to invest a minimum of $600
million into R&D for next generation 5G networks capable of speeds 100 times
faster than modern LTE networks
On 8 May 2014, NTT DoCoMo start testing 5G mobile networks with Alcatel
Lucent, Ericsson, Fujitsu, NEC, Nokia and Samsung.
At the end of September 2014, Dresden university inaugurates a 5G
laboratory in partnership with Vodafone
Uses UWB (Ultra Wide Band) networks with higher BW at low energy
BW is of 4000 Mbps, which is 400 times faster than today’s wireless
Uses smart antenna
UWB (Ultra Wide Band)
Uwb is an advanced transmission
technology that can be used in the implementation of 4G
network . The secret to uwb is that it is typically detected as
noise . This highly kind of noise does not cause interference
with current radio frequency devices
But it can be decoded by another device that recognizes uwb
and can reassemble it back to a signal.
It uses a frequency b/w 3.1 to 10.6 GHz.
Uwb uses frequency from high to low. There by passing
through objects like sea or layers of rocks , nevertheless
because of the weakness of the signal
Multiple “smart antennas” can be employed to help
find, tune, and turn up signal information. Since the
antennas can both “listen” and “talk,” a smart
antenna can send signals back in the same direction
that they came from. This means that the antenna
system cannot only hear many times louder, but
can also respond more loudly and directly as well.
There are two types of smart antennas:-
1.SWITCHED BEAM ANTENNA
Switched beam systems have several available fixed beam
A decision is made as to which beam to access, at given
point in time, based up on the requirements of system.
2.ADAPTIVE ARRAY ANTENNA
It represent the most advanced smart antenna
approach to date using a variety of new signal processing
algorithms to locate and track the user, minimize interference,
and maximize intended signal reception.
5G will be single unified standard of different wireless
networks, including LAN technologies, LAN/WAN,
WWWW- World Wide Wireless Web, unified IP &
seamless combination of broadband
Software defined radio, encryption, flexibility

Some major cities have deployed cameras on traffic
lights and send those images back to a central
command centre . This is generally done by using
fibre . Which limits where the cameras can be hung .
I.e. no fibre no camera. 5g network allows cities to
deploy cameras and backhaul them wirelessly .

Paramedic assisting a victim of a traffic
accident in a remote location could access
medical records and establish a video
conference that a remotely based surgeon could
provide “0n scene “ assistance .
Traffic Control during Disaster
If a hurricane hits the coast and cars start
driving south-east, 5g n/w can allow officials to access traffic
control boxes to change inland traffic lanes to green. Instead of
having to send officers to every box on the roads being
overwhelmed by civilians who are evacuating. It can be done
remotely and dynamically.
