After 5G, where do we go?
At the Brooklyn 5G Summit 2019, NYU Professor Ted Rappaport, whom I consider a communication visionary, gave a keynote talk about Terahertz Communication. 5G addresses mmWave technology at the high end which covers the 30 GHz to 300 GHz part of the spectrum. The next generation Terahertz region spans 300 GHz to 3 THz where the wavelengths go from 1 mm to as low as 100 μm. Rapport commented that all of the 5G work done for mmWave 5G will help carry developers over to the THz regime.
