From Information Theory to Space Laser Comms

The Necessity of a Multi-disciplinary Approach to Optical Wireless!

Due to the increasing scarcity of RF spectrum and growing interference due to multiple users, deploying next generation high-speed wireless networks is becoming increasingly difficult. The use of unlicensed optical bands for wireless communications has been heralded as an exciting development for future broadband access for indoor, over long distances terrestrially, underwater and for space communication links.

Why Optical Wireless Communication is Ready for 6G!

Security, energy efficiency, data density and peak data rates of up to 1 Tbps are some of the key performance indicators (KPIs) of 6G. With current radio frequency (RF) technologies it will be difficult to advance all these KPIs jointly due to fundamental spectrum limitations in the RF domain. What is needed to achieve step-change improvements in all those areas of interest, is substantial new spectrum, devices at high optical-to-electrical (OE) conversion efficiencies and the ability to spatially control signal radiation tightly and at low energy cost.
