LTE Advanced Pro - Overview                             Home :




What is LTE-Advanced Pro ?


Everybody would know what LTE Advanced mean ? Then what does 'Pro' mean ? 3GPP document would not explain it :). According to Reference [3], it would have multiple meaning as listed below (It sounds like marketing terms to me though).

  • Propel
  • Progress
  • Proliferate

Whatever it means, you may easily guess LTE-Advanced Pro will be an evolution of LTE Advanced.  

Then, what are the major technical features of LTE-Advanced Pro ? Let's find some clue from 3GPP official description (Ref [1]). It states as follows :


The major advances achieved with the completion of Release 13 include: MTC enhancements, public safety features such as D2D and ProSe - small cell dual-connectivity and architecture, carrier aggregation enhancements, interworking with Wi-Fi, licensed assisted access (at 5 GHz), 3D/FD-MIMO, indoor positioning, single cell-point to multi-point and work on latency reduction. Many of these features were started in previous Releases, but will become mature in Release 13.


Summarizing these features in bullets, it is as follows. I will update further details with focus on these features down the road.



UE Category


As you see here, a new Category 17 is added and theoretically it can support max 25 Gbps throughput. I think this can be achievable by taking 32 CC Carrier Aggregation and each carrier with 20 Mhz bandwidth.
