What is a wireless network..
 In the most general sense, a wireless system is
any collection of elements (or subsystems) that
operate interdependently and use unguided
electromagnetic-wave propagation to
perform some specified function
 Systems that convey information between two
or more locations, such as personal
communication systems (PCS), police and fire
department radio systems, commercial
broadcast systems, satellite broadcast systems,
telemetry and remote monitoring systems etc
come under this

Introduction to wireless networks
 The term "wireless" should not be confused with the
term “cordless", which is generally used to refer to
powered electrical or electronic devices that are
able to operate from a portable power source
(e.g., a battery pack) without any cable or cord to
limit the mobility of the cordless device through a
connection to the mains power supply.
 Wireless systems use different modes of
electromagnetic energy for the transmission of
information or data

Introduction to wireless networks
 TV remote controllers mostly use Infra-red light
energy to carry, or send the information from the
remote in your hand to the TV
 Remote garage door controllers use Radio
Frequency waves (usually just called RF).
This type of energy can usually penetrate glass
windows, walls and other non-metallic objects.
 The cellular phone system uses Microwaves
because it needs to carry such a vast amount of
information that it needs an extra-broadband
carrier and Microwaves can carry this big load. The
microwave transmitter and receiver work best in
line-of-sight with no objects in between.

Introduction
 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.

What is 5G ?
 5G as already mentioned also stands for 5th
generation wireless technology.
 It is a name which is used in some of the research
paper and going to become a next major phase
of mobile telecommunication beyond the current
4G standard.
 It is a concept which is only theory not real.
 It changes the way we are using wireless gadget
by providing very high bandwidth.
 It adds a no of advantages over the present 4g
technology.

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.

Architecture
OSI LAYERS 5G MOBILE NETWORK LAYER

 OWA stands for Open Wireless
Architecture. This layer is used to define
the wireless technology to be used.
Physical Layer + Data Link Layer=OWA
 Network Layer is divided into two sub
layers
1.Lower Network Layer
2.Upper Network Layer
 Network Layer is used to route the data
from source to destination
Architecture

Architecture
 Open Transport Layer perform the
operation of both transport layer and
session layer.
 Transport Layer + Session Layer=OTL
 Application Layer is responsible for
providing good quality of service.
 Application Layer makes the data into
proper format i.e. it decrypt the data
which is in encrypted form.

Hardware of 5g
 5G Hardware:
 Uses UWB (Ultra Wide Band) networks
with higher BW at low energy levels
 BW is of 4000 Mbps, which is 400 times
faster than today’s wireless networks
 Uses smart antenna
 Uses CDMA (Code Division Multiple
Access)

Millimeter waves
 The term millimeter waves generally refers to the
portion of electromagnetic spectrum between 30
and 300 GHz, corresponding to wavelength of 10 to
1 mm. Thus, the millimeter wave spectrum lies
between the microwaves and infrared portions.

Millimeter waves
Why mm wave may not be used
for communication systems….
 Unlike low frequency radio signals, millimeter waves
are not appropriate for long distance transmissions
through the atmosphere, due to higher signal loss
 Unless proper antenna designs are made mm
waves might not get materialized for high speed
wireless systems
 However because of their substantially higher
frequency comparing to conventional RF waves,
high speed wireless systems will have to depend
upon mm waves for transmission

Adaptive array transceiver
 In May 2013, Samsung electronics became the first
documented firm to have physically made a 5G
communication link. They used a part of the spectrum
which is known by the name millimeter band
 Samsung transmitted data in the millimeter-wave band at
a frequency of 28 GHz at a speed of up to 1.056 Gbps to
a distance of up to 2 kilometer The adaptive array
transceiver technology, using 64 antenna elements, can
be a viable solution for overcoming the radio
propagation loss.

Stages of development
The METIS project
• METIS, Mobile and wireless communications
Enablers for Twenty-twenty (2020) Information
Society.
• METIS is co-funded by the European
Commission as an Integrated Project under the
Seventh Framework Programme for research
and development (FP7).
• The project will provide an important platform
for a European-led early global consensus on
fundamental questions connected to the
development of the future mobile and wireless
communications system, and pave the way for
future standardisation of systems such as 5G.
