came early in 1970s.
 Uses electromagnetic waves,
such as radio waves

7. 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.
wikipedia

8.  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

9.  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)

11.  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

12. • 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.

14. • 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)

15. • 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

 Take a time of 2-5 mins. to download a 3 mins. Mp3 song

19. Mobile Technology and communication
• 3G Technology is designed for multimedia communication
• 1st lunched in Japan by NTT, 2001
• 3G has the following enhancements over 2.5G
• Enhanced audio and video streaming;
• Several Times higher data speed;
• Video-conferencing support;
• Web and WAP browsing at higher speeds
• IPTV (TV through the Internet) support.
• There are many 3G technologies

20. FEATURES INCLUDES
• Mobile Application ( Banking , Social Media, Music, E-book)
• Mobile Store application ( ITunes store , Play Store , Apps world)
• Video Streaming (YouTube)
• GPS ( Google Maps , etc)
• Send/Receive Large Email Messages
• Multimedia Service
• Data transfer rate:
144 Kbps – 2 Mbps
• 11 sec – 1.5 min. time to download a 3 min Mp3 song

21. DRAWBACKS OF 3G TECHNOLOGY
Expensive fees for 3G Licenses Services
It was challenge to build the infrastructure
for 3G
 High Bandwidth Requirement
 Expensive 3G Phones.
 Large Cell Phones

26. What is 4G ?
oIn 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.

27. What’s new in 4G ?
o IP (Internet Protocol)
based mobile systems.
o Entirely packet-switched
networks.
o Digital in nature
o Wider Bandwidths 100
Mhz
10 times faster than
current 3G
o Global mobility and
service portability.
o User Friendly.

30. WHICH COUNTRIES HAVE 4-G
Except for the Scandinavian countries, a few countries have
started the 4G commercially
In the UK, 4G SERVICE LAUNCHED BY EE IN OCTOBER 2012 AND BY
BY VODAFONE IN AUGUST 2013
IN CHINA THERE WERE 13.97 MILIONS 4G SUBSCRIBERS IN JUNE
2014 AND ALMOST ON 13.93 MILIONS CHINA MOBILES
Countries expected to launch 4G by this year are Germany,
Spain, India and England Completely
6.6 billion GSM, HSPA and LTE subscriptions and still
growing!

31. • Bharti Airtel launched India's first 4G service, using TD-LTE
technology, in Kolkata on April 10, 2012. Fourteen
months prior to the official launch in Kolkata, , a group
consisting of CHINA mobiles ,bharati airtel .and soft bank
mobile came together ,called Global TD-LTE Initiative
• Airtel 4G services are available in
Kolkata, Bangalore, Pune and Chandigarh region (The
Tricity or Chandigarh region consists of a major city
Chandigarh, Mohali and Panchkula.
• Bharti Airtel is launching 4G services in Delhi by Jan 2014[
• India uses the TD LTE frequency #40 (2.3 GHz), Apple iPhone
5s supports the TD LTE 40 band.

36. 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

39. 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

40. COMPONENTS (CONTD..)
OFDMA: Orthogonal Frequency Division Multiple Access.
• It captures entire energy
• Only few signals are affected or lost in OFDM while compared to
CDMA in 3G.
MIMO(Multi Input Multi Output):
• improve the communication performance between sender and
receiver
• range, quality of received signal and spectrum efficiency are
high.

41. 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 specific
time.

42. COMPONENTS(CONTD..)
Smart antenna
• Switched Antenna: Based on the requirement of the
system ,signal is received at any given time.
• Adaptive Antenna: Steer the signal at any direction of
interest ,nullify the interfering signal.

43. High usability:
anytime,
anywhere, and
with any
technology.
• Support for
multimedia
services at
low
transmission
cost.
• Higher
bandwidth,
tight network
security.
