The document discusses the evolution of mobile network technologies from 1G to 4G. It provides an overview of each generation including key features and limitations. 4G is described as providing high-speed internet access anywhere, utilizing smart antennas and high resolution mobile TV. It offers significantly higher data transfer rates and bandwidth compared to 3G. The document also outlines applications of 4G, the current status of 4G in Pakistan, and challenges in implementing the new technology.

Signal Quality Good Best
Communication Type Circuit Switching Packet Switching

7. Why 4G is Better than 3G
Technology 3G 4G
Data Transfer Rate 3.1 MB/sec 100 MB/sec
Internet Services Broadband Ultra Broadband
Mobile - TV Resolution Low High
Bandwidth 5-20 MHz 100MHz
Frequency 1.6-2 GHz 2-8 GHz

8. Applications of 4G
 Better Usage of Multimedia Applications.
 Video Conferencing.
 Graphical Maps of streets, buildings, and
physical characteristics of a large metropolis
on a vehicle.

9. 4-G in PAKISTAN
 Government has already Auctioned the 3G and 4G Licenses
 Pakistan is among the latecomers in 3G but not very late in 4G
 3 Telecom Companies bided for 3G Technology. i-e. Ufone, Mobilink,
Telenor.
 Zong bided highest amount for only 4G Spectrum.
 3G auction was postponed by government for more than 1 year due to
some personal political wishes but at last Supreme Court of Pakistan
ordered PTA for the auction of 3G and 4G spectrum and hence it
happened.

10. Advantages of 4G
 Affordable communication services.
 High speed high capacity and low cost per bit.
 Support for interactive multimedia, voice ,
streaming video, Internet and other broadband
services.
 Global access, Service portability and scalable
mobile services and variety of quality of services
provided.
 Better spectral efficiency.

11. Disadvantages
 Battery usage is more.
 Hard to implement.
 Need complicated hardware.
 The equipment required to implement a next generation
network is still very expensive.
 4G Device Needed to avail services of 4G Technology.

12. Challenges
 Competition with the next forth coming 5G.
 5G technology is providing large broadcasting of
data in Gigabit which supports almost 65,000
connections.
 5G technology would provide better use of available
bandwidth.

13. Conclusion
