Unlocking the potential of Terahertz spectrum

Ofcom is seeking opinions on how to maximise the long-term value of Terahertz spectrum. Terahertz spectrum is between around 100 GHz and 3 THz – at the very top of the spectrum range currently authorised for use. It’s currently used for limited scientific applications – including to deliver high-sensitivity measurements for weather forecasting and climate change predictions. Nonetheless advances in technology are starting to open up further opportunities.

Terahertz spectrum could, for example, enable:
• Terabit-speed downloads for very short-range computer communication
• Robotic controls
• Autonomous vehicles
• High-definition holographics and high-speed wireless data distribution
• Applications likely to evolve in 6G networks

To help realise the full advantages of Terahertz, Ofcom intend to ensure their approach to managing spectrum is as flexible and efficient as possible – both to enable existing services to grow as well as supporting innovative new ones.

The unique properties and capabilities of new technologies mean the rules and approaches to spectrum authorisation that apply at lower frequencies need not dictate the way we approach the authorisation and use of Terahertz spectrum. Greater collaboration and cooperation between the different types of emerging spectrum users in these bands will be essential in underpinning an alternative approach. More details can be found here.
