Wireless network refers to any
type of computer network that is
wire-less
Mobile wireless technology
came early in 1970s.
Uses electromagnetic waves,
such as radio waves

WHAT IS G????
The use of G, standing for generation in mobile
technology covers the major advances of the
past 20-30 years. Since the first generation of
so-called “analog” mobile radio networks
was created in 1980, the mobile telephone has
seen many upheavals.

MTS(Mobile Telecommunication service)
• Analog system telecommunication
• Setup By Operator
• It is very heavy in weight and big size
• There were initially only 3 channels for all the
users in the metropolitan area
• Generally Mobile Radio Telephone system provides half
duplex communications i.e. only one person will speak
and other should hear
![Page 9: ppt on 4g in detail from og to 4g](https://reader034.fdocuments.us/reader034/viewer/2022042700/5598f6e21a28ab5f278b462a/html5/thumbnails/9.jpg)
In 1960, a system launched by Bell Systems, called IMTS, brought
quite a few improvements such as direct dialing and more
bandwidth.
IMTS(Improved Mobile Telecommunication service)
• Simultaneously Call
• Reduced Size and weight
• Eliminate Setup by Operator
• The total to 32 channels across 3 bands
Frequency 450 -470 MHz
• Feature Includes
• Voice Call Analog
• These mobile telephones were placed in vehicles (truck, cars
etc). The mobile telephone instrument had two main parts
those were transceiver (transmitter – receiver) and head
(instrument which had display and dial keys)

The first commercially automated cellular network (the
1G generation) was launched in Japan by NTP (Nippon
Telegraph and Telephone) in 1979.
NMT (Nordic Mobile Telephone) system in 1981,by Denmark, Finaland etc.
AMPS(Advanced Mobile Phone Service)
• Frequency 800 MHz
• Analog Systems

• Feature Includes
• Voice Call Analog
• Text message also possible with some sophisticate
devices
• It has low capacity, unreliable handoff
• poor voice links
• no security at all
• It allows the voice calls in 1 country.

• 2G technology refers to the 2nd
generation which is based on GSM.
• GSM ( Global System Mobile
Communication)
• It was launched in Finland in the year
1991.
• 2G network use digital signals.
• Sim Card
(Subscriber Identity Module)
![Page 15: ppt on 4g in detail from og to 4g](https://reader034.fdocuments.us/reader034/viewer/2022042700/5598f6e21a28ab5f278b462a/html5/thumbnails/15.jpg)
• It enables services such as text messages, picture messages.
• It provides better quality and capacity .
• 2G requires strong digital signals
to help mobile phones work. If there
is no network coverage in any specific
area , digital signals would weak.
• These systems are unable to
handle complex data such as Videos

What is 4G ?
o In telecommunication systems, 4G is
the fourth generation of mobile phone mobile
communication technology standards. It Is a
successor to the third generation (3G)
standards. A 4G system provides mobile ultra-
broadband Internet access, for example to
laptops with USB wireless modems,
to smartphones, and to other mobile devices.
Conceivable applications include a
mended mobile web access, IP telephony,
gaming services, high-definition mobile TV,
video conferencing, 3D television, and cloud
computing.

How 4G Works ?
• The IP address is based on IPv6.
• IPv4: X . X . X . X (32 bits)example: 10.0.17.189
• IPv6: 4 × IPv4 (128 bits)
• example:216.37.129.9 , 79.23.178.229 , 65.198.2.10 , 192.168.5.120

COMPONENTS OF 4G:• There are some components which makes the successful 4G systems
they are:
a) OFDMA
b) MIMO
c) IPv6.0
d) SDR(Software Defined Radio)
e) Smart antennas
![Page 40: ppt on 4g in detail from og to 4g](https://reader034.fdocuments.us/reader034/viewer/2022042700/5598f6e21a28ab5f278b462a/html5/thumbnails/40.jpg)
COMPONENTS (CONTD..)
OFDMA: Orthogonal Frequency Division Multiple Access.
• It captures entire energy
• Only few signals are affected or lost in OFDM while compared toCDMA in 3G.
MIMO(Multi Input Multi Output):
• improve the communication performance between sender andreceiver
• range, quality of received signal and spectrum efficiency arehigh.
![Page 41: ppt on 4g in detail from og to 4g](https://reader034.fdocuments.us/reader034/viewer/2022042700/5598f6e21a28ab5f278b462a/html5/thumbnails/41.jpg)
COMPONENT (CONTD..)
IPv6.0:
• Allows more address than IPv4.0
• IPv6 each device have own IP address.
SDR(Software Defined Radio):
• A SDR will allow increasing network capacity at specifictime.
