4G is not a single technology but a collection of technologies that create fully packet-switched networks optimized for data transmission. 4G networks are projected to provide speeds of 100Mbps for mobile users and 1Gbps for stationary users. The development of wireless technology progressed from 1G which used analog signals for early mobile phones, to 2G which used digital signals and had better quality and capacity, to 3G which enabled broadband capabilities and multimedia support, to 4G which provides faster speeds and more services including mobile gaming and broadband access in remote areas. Research into 5G networks is already underway to continue advancing mobile communication technology beyond 4G.

1. 4G Technology Presented By Rinshad Akbar k

2. 4G Definition 4G is not one defined technology or standard, but rather a collection of technologies at creating fully packet-switched networks optimized for data. 4G Networks are projected to provide speed of 100Mbps while moving and 1Gbps while stationary.

3. 1G Technology 1G refers to the first-generation of wireless telephone technology was developed in 1970’s. Analog signals is used

4. 1G mobile phones

5. 2G Technology Around 1980’s Better quality & capacity - More people could use there phones at the same time Digital Signals – consist of 0’s & 1’s

6. 2G Technology

7. 2G mobile phones

8. 3G Technology Large capacity and broadband capabilities Allows the transmission of 384kbps for mobile systems and up to 2Mbps

9. 3G support Mobile phone

10. Reasons for New Research Even though 3G has successfully been introduced to mobile users, there are some issues that are debated by 3G providers and users. High input fees for the 3G service licenses Great differences in the licensing terms 3G phones are expensive

11. Fourth Generation

13. WHY 4G? 1G Analogy Communication 2G Digital Communication 3G Multimedia 4G More Services

14. What is 4G? Fourth Generation Technology Faster and more reliable 100 Mb/s Lower cost than previous generations Multi-standard wireless system Bluetooth, Wired, Wireless Ad Hoc Networking IPv6 Core Primary technologies that support 4G Eg::WiMax,LTE,UMB

15. Ad Hoc Networks Spontaneous self organization of networks of devices 4G will create hybrid wireless networks using Ad Hoc networks Form of mesh networking–Very reliable

16. Enhance Mobile Gaming Experience enhance wireless capabilities that deliver mobile gaming interaction with less than five seconds Play online multi player games while traveling at high speeds or sitting outside

17. Broadband access in Remote location 4G will provide a wireless alternative for broadband access It will provide first opportunity for broadband access in remote locations without an infrastructure to support cable

18. 4g mobile phone

21. CONCLUSION: 4G is not a final solution in mobile communication…..The research is going on… Now a days 5G ( 5th generation mobile networks or 5th generation wireless systems ) is a name used in some research papers and projects We can expect ‘NEW’ within some months
