Applications of 4G
4-G in PAKISTANo Government has already Auctioned the 3G and 4G Licenses
o Pakistan is among the latecomers in 3G but not very late in 4G
o 3 Telecom Companies bided for 3G Technology. i-e. Ufone, Mobilink, Telenor
o Zong bided highest amount for only 4G Spectrum
o 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.
Disadvantages
o Battery usage is more
o Hard to implement
o Need complicated hardware
o The equipment required to implement a next generation network is still very expensive.
o 4G Device Needed to avail services of 4G Technology
Challenges
o 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……..
