The measure also sets aside 21.2GHz of spectrum to share for unlicensed devices. The airwaves in question were chosen to minimize possible interference with current “governmental and scientific” uses in those areas, such as space science.

These frequencies could lead to extremely fast wireless network data, advanced imaging and very fine-grained sensors, among other purposes. However, you might not want to get your hopes up for a cellphone with terahertz 6G any time soon. Even more so than with millimeter waves, the terahertz range would be limited by short ranges and difficulty penetrating objects. That’s what the experiments are for, though — it could establish uses that aren’t even on the radar yet.
