Evolution of Mobile technology :

4. What is 4G ?
o Fourth Generationof CellularCommunications.
o Beyond 3G .
o Datatransferrate up to 100 Mbps for highmobility
and 1 Gbps for low mobility .

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

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

7. 4G Hardware :
oUltra Wide Band Networks
oSmart Antennas
4G Software :
oSoftware DefinedRadio
oPacket Layers
oPackets

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 therequired rate in a
high-densityarea .
o usefulwhenit is bundled withIPTV.
o The wireless bandwidth willbe roughly3Mbps/1.5Mbps; but
this is nowhere near the100Mbps/50Mbps thatLTE
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
frequencies.

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

• Virtual Presence
• Virtual Navigation
• Crisis ManagementApplication
• 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
• Need complicated hardware.
