Summary
Which frequency bands 6G will use, including THz frequencies above 100 GHz and the candidate 7–24 GHz range, and the semiconductor challenges involved in delivering adequate output power at sub-THz bands. How artificial intelligence and machine learning can replace traditional signal-processing blocks with trained autoencoder models, and how joint communications and sensing (JCAS) enables the mobile network to serve both data transmission and environmental perception. How reconfigurable intelligent surfaces use programmable metamaterials to control the radio propagation environment, and how photonics technologies including visible light communications and quantum key distribution extend network capacity and security. How ultra-massive MIMO, full-duplex communications, new waveforms, non-terrestrial networks, and cell-free architectures converge to create a unified 3D “network of networks” with ubiquitous coverage and dramatically higher spectral efficiency.
