FCC puts spectrum above 95 GHz on the map, terahertz looms

Even before regulators outside the USA have decided on their timescales and policies for millimeter wave spectrum, researchers are already casting their eyes upwards to the airwaves above 95 GHz. Last week, the USA’s FCC approved experiments in these very high bands. Just as mmWave spectrum up to 90 GHz is synonymous, for many, with 5G, so vendors and academics often link even higher bands with ‘6G’. Bluesky projects looking at post-5G generations of wireless technology are heavily focused on new spectrum options, and the technologies to address their implementation challenges. None of this will become real for a decade at least, but the FCC’s decision does take very high frequencies out of the realm of fantasy and put them…
