Ofcom is asking for views on how to maximise the long-term value of the Terahertz (THz) spectrum, extremely high frequencies that could provide huge bandwidth for applications of the future and enable 6G networks.
The Terahertz band sits at the very top of the spectrum range between 100GHz and 3THz and is currently only used for limited scientific applications, such as weather forecasting.
