Prof. Ted Rappaport has featured a few times in our blog posts (see here and here). Today we look at his recent keynote at the EuCNC & 6G Summit 2023 on the topic ‘Looking Towards the 6G Era – What we may expect, and why’. The abstract of the talk says:
Recent work has shown that the fundamentals of the radio propagation channel will enable mobile communications all the way to 900 GHz, offering bandwidths of tens of GHz. An amazing fact that is all but disregarded is that the three fundamental technological breakthroughs of 5G, namely millimeter wave technology, small cell densification, and massive multiple-input multiple-output (massive-MIMO) antenna systems, are paving the way for the next several decades of the wireless industry. This talk demonstrates how the 5G era will futureproof wireless networks as we enter the 6G era and beyond — an era of wireless cognition and human-style computing. In fewer than 20 years, wireless networks will carry information at the computation speed of the human brain. Yet, how will engineers ensure that we build these networks with sustainability and power efficiency in mind? This talk offers some solutions and promising areas of exploration to ensure the future 6G era is lightning fast yet kind to planet earth.
Next G Alliance has a nice short report looking at ‘Terminology for Frequency Ranges’. Handy and useful charts – https://t.co/kfJFxcdUDo via @atisupdates @NextGAlliance #Free5Gtraining #3G4G5G #ATIS #NGA #5G #B5G #6G #Frequency #Spectrum #Bands #mmWave #cmWave #THz pic.twitter.com/Nyoh1X0asX

Recently I had a discussion about mmWave, sub-THz, THz, etc. This chart in the Tweet above is handy with deciphering the 5G/6G spectrum terminology.
Prof. Rappaport covered quite a few topics on spectrum above 100 GHz and made a strong case for mmWave and Terahertz. The mmWave adoption for 5G hasn’t yet taken off so we will have to see how enthusiastic the industry is for even higher frequencies. The other keynotes from the conference (see references below) argued for cmWave as the mid-band for 6G. We will have to wait and see where all this discussion goes.
