LTE-Advanced, just like 4G will become 4.5G and 4.9G before 5G is released. You
will see great increases in speed and LTE will become more and more advanced. It
is quite impressive what the OEMs are doing.
The HetNet will be an applicable term. Networks will handoff between so many
different types of systems. However, I do believe that the 5G systems may be a type
of LTE to hand off to each other properly. Remember that there will be multiple
systems running simultaneously. They would need to have a seamless handoff for
the best user experience.
I will use an example. The carriers have truly adopted wi-fi because of the
complexity of the shift from LTE to Wi-Fi, that is why the carriers are so excited
about LTE-U. The see a viable way to make the best use of unlicensed spectrum.
The Wi-Fi carriers don’t like it because they invested a lot of money into their
license free Wi-Fi networks.
The 5G systems will need to have a way to such seamless handoffs without
dropping a call or a session.
