Sub-THz
Sub-Terahertz Frequency Spectrum (90 GHz to 300 GHz)
The newly unlocked electromagnetic spectrum band between 90 GHz and 300 GHz offering tens of gigahertz of contiguous bandwidth for Tbps data rates.
Technical Explanation
Sub-THz represents the primary frontier for extreme throughput and centimeter-level sensing in 6G. Situated between traditional millimeter waves and optical infrared, Sub-THz bands (including the 90-110 GHz W-band, 110-170 GHz D-band, and 220-300 GHz G-band) provide massive contiguous channel bandwidths (up to 10-30 GHz per carrier). These bands enable terabits-per-second (Tbps) data rates for wireless backhaul, chip-to-chip interconnects, and holographic streaming, but require extreme beamforming to overcome atmospheric attenuation and molecular absorption.
Key Functions
- Contiguous bandwidth allocations exceeding 10 GHz for peak throughput >100 Gbps to 1 Tbps
- Extremely narrow beam angles (<1 degree) providing high angular resolution for radar sensing
- Miniaturized antenna components enabling thousands of elements in smartphone form factors
- High-capacity wireless fronthaul/backhaul replacing physical fiber in dense urban cores
- Short-range ultra-secure data kiosks and chip-to-chip wireless communications
