Roads to 5G Communications 2021 Report: Cognitive Radio/Software Defined Radio, Small Cells, mmWave Radio, MIMO and Visible Light Communication

DUBLIN, May 11, 2021 /PRNewswire/ -- The "Roads to 5G Communications: Technologies, Applications and Markets Assessment" report has been added to's offering.

Research and Markets Logo

The goal of this report is to address several current technologies (as well as their markets, applications, and other characteristics) that, according to the ITU classifications, are transitioning to the 5G communications era.

Though based on the industry insiders statistics, in 2019 market share of 4G networks was not more than 7%-12% on the global scale, the industry is already (2018-2020) supporting commercial 5G introduction in several market regions and applications.

This new radio access generation will be built on the existing infrastructure, which will be modernized and expanded with new technologies.

The 5G wireless communication system will be a converged system with multiple radio access technologies integrated together. It will be able to support a wide range of applications and services to comprehensively satisfy the requirements of the information society by the year 2020 and beyond. From the technology perspective, 5G will be the continuous enhancement and evolution of the present radio access technologies, and also the development of novel radio access technologies to meet the increasing demand for the future. 5G can be characterized as data, connectivity and user experience.

There are two main views on 5G that exist today, which are frequently mixed together to form the basis of the 5G definition:

View 1 - The hyper-connected vision: In this view, 5G is seen as a blend of existing technologies (2G, 3G, 4G, Wi-Fi, and others) that can deliver greater coverage and availability, higher network density in terms of cells and devices, and the ability to provide the connectivity that enables machine-to-machine (M2M) services and the Internet of Things (IoT).

View 2 - Next-generation radio access tchnology: This perspective outlines 5G in 'generational' terms, setting specific targets that new radio interfaces must meet in terms of data rates (faster than 1Gbps downlink) and latency (less than 1ms delay).

The first view is connected with a gradual transition of 3G/4G (and other) technologies to the 5G era with appropriate enhancements and extensions. Some of such technologies are the subject of this report analysis.

In particular, the following technologies, their markets, industries, and applications are addressed in connection with their transition to 5G (they are being bundled under the title of 5G despite the fact that they are already being brought to market by vendors and deployed by operators):

CR/SDR - Cognitive Radio/Software Defined Radio

  • Though the concept of CR/SDR is well known and the industry supports these techniques for a number of years, the 5G era will bring new requirements to network characteristics that can be easy to fulfill with CR/SDR.
  • The 5G "Network of Networks" needs further development of the CR/SDR concept responding to particulars of 5G and using the existing base of smart radios.

Small Cells

  • It is expected that small cells will prevail in the 5G infrastructure due to advanced features that satisfy 5G requirements.

mmWave Radio

  • mmWave Radio will play an important role in the 5G RANs, allowing us to explore the vast amount of free spectrum.


  • Complex smart antenna systems such as MMIMO expected to be used extensively.

Visible Light Communication

  • VLC open several important applications, which were difficult to utilize in other spectrum windows.

The report also addresses general requirements to 5G networking and surveys current 5G standardization activities. It also contains the author's survey of recently approved patents related to VLC and MIMO technologies.

The report is intended for a wide audience of technical and managerial staff involved in the development of advanced wireless communications.
