Interest is rising in transmission at THz frequencies, an order of magnitude or more above mmWave, for a variety of potential use cases – with R&D focused on overcoming power dissipation and reliability issues. The better these challenges can be addressed, the greater the range of possible use cases. These higher frequencies are attractive for the same reasons as mmWave, but even more so. The main draw is the huge amount bandwidth available following in principle from the bigger numbers and therefore wider spectral bands involved, and also more accurate location detection. The latter follows from the shorter wavelengths, which equates roughly to the position sensing accuracy possible. In fact, frequencies defined as lying in the THz range are between…
