4. 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
5. 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
6. 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.

9. 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.
10. 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.

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.

20. 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
21. 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.
23. 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)
24. 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.
25. 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
26. 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.
30. Proposed software of 5g
5G Software:
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, Anti-Virus

Integration of various standards: Each engineering practice has their own standard, To integrate these various standards, requires systematic and time consuming approach.
Common Platform: There is no common architecture for interconnecting various engineering practices. One common governing body is required, which creates a common platform for all engineering practices to regularize the interconnectivity issues as well as knowledge sharing
