1G WIRELESS TECHNOLOGY
Using Analog signals
 Listen to handset
 Frequency typically 150MHz & above
Poor voice quality
 Poor battery life
 Large phone size
 No security
 Frequent call drops
 Limited capacity and poor handoff
reliability.
 2G phones using global system for mobile
communications (GSM) were first used in the
early 1990 s in Europe. GSM provides voice and
limited data services and uses digital
modulation for improved audio quality.
Digital AMPS , CDMA were some of the 2G
systems.
• Text
• SMS
• Fax
• 2 Dimensional
The GSM is a circuit switched , connection
oriented technology, where the end systems are
dedicated for the entire call session.
 This causes inefficiency in usage of
bandwidth and resources.The GSM enabled
systems do not support high data rates. They are
unable to handle complex data such as video.
Reduce range of sound.
Weaker digital signal.
o Phone calls/ Fax
o Voice mail
o Send/Receive e-mail messages
o web browsing
o camera phones
o speed: 64-144 kb/sec
o Time to download a 3 min MP3 song 6-9 min
THIRD GENERATION
 To meet the growing demand in network capacity, rates
required for high speed data transfer and multimedia
applications , 3G standards started evolving.
 It is based on the International
 Telecommunication Union (ITU) family of standards.
 3G technologies enable network operators to offer users a
wider range of more advanced services.
 Services include wide-area wireless voice telephony, video-
calls and broadband wireless data , all in a mobile
environment.
 The data are sent through the technology called
Packet switching.Voice calls are interpreted
through circuit switching.
Features includes


MOBILE WIRELESS TECHNOLOGY
 3G technology has taken the gaming to the
next level.
 Real-time multiplayer gaming is possible in
3G system.
 Innovative new services are being added by
developer daily.
EXTENDING TV TO
MOBILES
 Not simply rebroadcast of TV or website.
 Enhanced existing service for mobile
environment.
 Multi-faceted – 24*7 access to multiple live
streams , video , image & text content , voting ,
messaging.
 User interaction on multiple levels
 Video-Conferencing
ADVANTAGES OF 3G
MOBILE WIRELESS TECHNOLOGY
ANYTIME,ANYWHERE
CONNECTION ‘’4G’’
 Also known as “Mobile Broadband Everywhere”
One of the terms used to describe 4G is:
 Mobile Multimedia
Anytime Anywhere
Global mobility Support
Integrated wireless solution and
Customized personal service.
WHAT IS 4G???
 Faster and more reliable – 100 Mbps
 Lower cost than previous generations.
 Multi-standard wireless system
- Bluetooth , Wifi
 Coverage of wide area.
 Wide Variety of services capability.
 Ad Hoc networking
 IPv6 core
 Potentially IEEE standards 802.11
 Only packet switching used unlike previous generations.
 OFDMA(Orthogonal Frequency Division Multiple access)
and MIMO(Multiple In Multiple Out) replace CDMA
spread spectrum radio technology.
3G VS 4G
Specifications 3G 4G
Frequency band 1.5- 2.8 GHz 2-8 GHz
Band width 5-20 MHz 5-20 MHz
Data rate upto 2 Mbps 20 Mbps or more
Access wideband CDMA Multi-carrier-CDMA
or
OFDM(TDMA)
FEC Turbo codes concatenated codes
Switching Circuit/ Packet Packet
Top speeds 200kmph 200kmph
Estimation of Global
Wireless Subscriber
growth
ADVANTAGES OF 4G
 High usability: anytime, anywhere and with any
technology.
 Support for multimedia services at low
transmission cost.
 Higher bandwidth , tight network security.
DISADVANTAGES OF 4G
 The equipment required to implement a next
generation
network is still very expensive.
 Carriers and providers have to plan carefully to
make sure
that expenses are kept realistic.
