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.
