What is 4G and Long Term Evolution Advanced? - Explained

After introducing Long Term Evolution which is considered as 3.9G or Cellular network generation 3.9, 3GPP made enhancements and released the release version 10 in March 2011.


What is Long Term Evolution Advanced?

LTE Advanced or Long Term Evolution Advanced considered as the 4th Generation or the 4G cellular network that we use in most of the countries.

LTE Advanced uses the same frequencies which used by the LTE or long term evolution cellular networks.
