“Progress in Optical Wireless Communications – Visible Light Communications and Free Space Fiber” Technologies, Applications and Markets

This Practel report continues the company’s project on optical wireless communications (OWC).  It revises and updates Practel reports on this subject published previously.

Particular, the report concentrates on: 

  VLC – Visible Light Communication
  FSF – Free Space Fiber.

In connection with VLC development, the report is addressing Light Emitting Diode (LED) technologies and markets. LED, in the near future, will be a dominate source of illumination; and used also as a transmitting device.  The VLC LED-based channels promise to deliver high-speed data in office, home and other environments with high signal-to-noise ratio, and minimum infrastructure expenses.

The report is analyzing the emerging VLC industry, economics, technologies, standardization and applications. It shows that the spectrum of VLC applications is increasing each year to support such developments as Intelligent Transportation Systems, Localization and other. The report also surveys VLC-related patents (2017-2019).

FSF devices are solving access issues in metro and LAN environments. They are relatively inexpensive, support Gb/s rates of transmission; they are also offering low maintenance cost, guarantee a short installation time and security of communications. The report presents the FSF technologies and market analysis as well as discusses their applications together with the survey of vendors and their portfolios.

This report is important to a wide population of researches, technical and sales staff involved in the developing of advanced Optical Wireless Communications methods.  It is recommended for both service providers and vendors that are working with related technologies.
