3. Evolution of Mobile technology :
o 1G-First Generation
• Speech
o 2G-Second Generation
• SMS , MMS
• CDMA , GPRS , EDGE
• Voice Mail
o 3G-Third Generation
• Wireless Internet
• Video Calling
• Mobile TV

4. What is 4G ?
o Fourth Generation of Cellular
Communications .
o Beyond 3G .
o Data transfer rate up to 100
Mbps for high mobility
and 1 Gbps for low mobility .

5. What’s new in 4G ?
o IP (Internet
Protocol) based
mobile systems.
o Entirely packet-
switched networks.
o Digital in nature
o Wider Bandwidths
100Mhz

6. o 10 times faster than current 3G
o Global mobility and service
portability.
o User Friendly.
MAGIC :
M : Mobile Multimedia
A : Anytime / Anywhere
G : Global Mobility Support
I : Integrated
C : Customized Personal Network

7. 4G Hardware :
o Ultra Wide Band Networks
o Smart Antennas
4G Software :
o Software Defined Radio
o Packet Layers
o Packets

8. Technology Standards :
• WiMAX ,LTE
• The advantages of LTE are:
(i) 100 Mbps - download & 50 Mbps –
upload
(ii) It offers both FDD and TDD duplexing
(iii) Uses OFDM

9. WIMAX:
o WiMax technology might not
achieve the required rate in a high-
density area .
o useful when it is bundled with IPTV.
o The wireless bandwidth will be
roughly 3Mbps/1.5Mbps; but this is
nowhere near the 100Mbps/50Mbps
that LTE promises

10. OFDM :
• OFDM stands for
Orthogonal
Frequency Division
Multiplexing.
• It distributes the
data over a
large number of
carriers that are
spaced apart at
precise

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

12. Applications :
• Virtual Presence
• Virtual Navigation
• Crisis Management Application
• Telegeoprocessing, telemedicine
• Security

13. Advantages :
• High usability: anytime, anywhere, and
with any technology.
• Support for multimedia services at low
transmission cost.
• Higher bandwidth, tight network security.
Disadvantages :
• Expensive.
• Battery uses are more.
• Hard to implement
