3. Introduction about 4G Wireless
Technology
1. 4G=4th Generation Mobile Communication
2. A 4G Wireless System provides an end to end IP
solution where voice, data and streamed multimedia
can be served to users on an “Anytime,Anywhere”basis
at higher data rates than previous generations.
3. Data rates=50-100 Mbps
4. It has wider bandwidth
5. End to end Quality of Service
6. Higher Security

4. General 4G Services and 4G Applications
1) Localized/Personalized Information
2) Organizational Services
3) Communication services and applications
4) Entertainment Services
5) Mobile commerce

5. Evolution of 1G to 4G System
A. 1G Wireless System:-Developed in 1980s and
completed in early1990s.
B. 2G Wireless System:-2G phase began in 1990s and
much of this technology is in use.
C. 3G Wireless System:-It was developed in 1990s until
present days,Japan is first country having introduced
3G nationally.
