This makes sense from an economic scarcity standpoint, as a fairly large number of channels are available for use in unlicensed bands (more than 500MHz in many regions). It was introduced in 2015 and allows mobile users to simultaneously use both licensed and unlicensed spectrum bands at the same time. In short, Licensed Assisted Access (LAA) is the 3GPP’s effort to standardize LTE use inside of 5GHz WiFi spectrum. This will primarily be achieving using a new development called “Licensed Assisted Access.”
Qualcomm’s second bullet point is to basically make native use of Carrier Aggregation with LTE Advanced Pro by supporting up to 32 carriers at once across a much fatter bandwidth pipe. The first point describes delivering fiber-like speeds by using Carrier Aggregation (introduced with “LTE Advanced” networks in 2013) to aggregate both licensed and unlicensed spectrum across more carriers, and to use simultaneous connections to different cell types for higher spectral efficiency (for example: using smaller, single-user pCells combined with large, traditional cell towers).
In its new 4.5G presentation, Qualcomm has highlighted ten major bullet points that it expects to be present in its next-generation LTE “Advanced Pro” specification. Qualcomm – The road from LTE Advanced (2013 - Present) to LTE Advanced Pro (2016 - 2020) The company intends to make LTE Advanced Pro an opportunity to use up more spectrum before 5G networks launch next decade and wants it to support further backwards-compatibility with existing LTE deployments, extremely low latencies, and unlicensed spectrum access, among many other new features. This will be an “intermediate” standard before the wireless industry continues with “Release 15” in 2020 and beyond, also known as 5G technology.
