3. Evolution of Mobile Technology :
o 1G-First Generation (1979 in Japan)
• Speech
o 2G-Second Generation (1991 in Finland)
• SMS , MMS
• CDMA , GPRS , EDGE
• Voice Mail
o 3G-Third Generation (1998 in Japan)
• 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.

5. 3G vs 4G

Technology 3G 4G
Data Transfer Rate 14.1MB /sec 100MB/sec
Internet services Broadband Ultra Broadband
Mobile -TV
Resolution
Low High
Bandwidth 5 - 20 MHz 100 +MHz
Frequency 1.6- 2 GHZ 2 – 8 GHz
Network Architecture Wide Area Network Hybrid Network

6. What’s new in 4G ?
o IP (Internet Protocol) based
mobile systems.
o Digital in nature
o Wider Bandwidths 100Mhz
o 10 times faster than current
3G
o User Friendly.

7. Technology Standards :
• LTE (In Norway ,Sweden since 2009)
• The advantages of LTE(Long Term Evolution) are:
(i) 100 Mbps - download & 50 Mbps – upload.
(ii) It offers both FDD (Feature Design Document) and
TDD (Test Driven Development) duplexing.

8. 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

9. Applications :
• Virtual Presence :-for ex.-Always-on connections to
keep people on event and also video conferencing.
• Virtual Navigation :-A remote data base contains the
graphical representation of streets, building and
physical characteristics.
• Telegeoprocessing :-Dependent on location
information of several users.
• Security:-

10. 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.
