Frequency bands above 6 GHz are candidate for 5G mobile communications because there are up to tens of GHz of spectrum available. Promising 5G techniques include novel beamforming techniques using massive antenna arrays, low form factor chip-scale antennas for base stations and user devices, adaptive backhauling and various system and deployment issues. Recently, THz bands are becoming promising techniques for 5G enhancements or beyond 5G systems. The ultra-high data rate enables THz in applications to a wide range of short range communications. This workshop will provide a forum for both industry and academia to exchange views and visions.
