Why 4G is Better than 3G

Better Usage of Multimedia Applications.

Video Conferencing.

Graphical Maps of streets, buildings, and

physical characteristics of a large metropolis on a vehicle.

Applications of 4G

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.

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.

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.

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.

Conclusion

Mobile…. Multimedia …..Anytime….. Anywhere….. Global mobility…..Integrated wireless…..Personalized services…..

That’s……..
