  1. 1. Presented by : Krishna Mohan Shakya BCA- III sem Section-A
  2. 2. OVERVIEW: o Evolution of Mobile Technology o What is 4G? o 3G vs 4G o Technologies Standard o How 4G Works? o Applications o Advantages and Disadvantages o Conclusion
  3. 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. 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. 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. 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. 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. 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 Home Address Care of Address Mobile IP address Local network address
  9. 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. 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.
  11. 11. CONCLUSION  4G Can be best described in word MAGIC : M : Mobile Multimedia A : Anytime / Anywhere G : Global Mobility Support I : Integrated C : Customized Personal Network
