LTE Pro will be an "intermediate" standard before the wireless industry continues with "Release 15" in 2020 and beyond, also known as 5G technology. LTE Advanced Pro is essential Rel 13/14. Below is what LTE Advanced Pro will deliver. Carrier Aggregation Delivering fiber-like speeds by using Carrier Aggregation (introduced with "LTE Advanced" networks in 2013) to aggregate more carriers, and to use simultaneous connections to different cell types for higher spectral efficiency LAA In short, Licensed Assisted Access (LAA) is the 3GPP's effort to standardize LTE use inside of 5GHz WiFi spectrum. It was introduced in 2015 and allows mobile users to simultaneously use both licensed and unlicensed spectrum bands at the same time.  Full Dimension MIMO This technology uses elevation beamforming by using a 2D antenna signal array in order to exploit 3D beamforming. Later down the road in 3GPP Releases 14 and beyond, we can expect support for higher-order "
