Sub-THz
Sub-terahertz frequencies (100–300 GHz) are candidate bands for 6G and 7G networks. They offer massive bandwidth — up to 10 GHz per channel — enabling multi-gigabit wireless links. However, sub-THz signals are blocked by walls, absorbed by rain, and require highly directional antennas.

Terahertz waves occupy the electromagnetic spectrum between 0.3 and 10 THz. They are the target frequencies for 7G networks, theoretically capable of delivering 10+ Tbps data rates over short distances
Millimeter wave (mmWave) refers to radio frequencies between 24 and 100 GHz, characterized by short wavelengths (1–10 mm). In 5G, mmWave enables high-capacity urban hotspots with speeds exceeding 1 Gbps
Beamforming is a signal processing technique that uses multiple antenna elements to focus radio signals in specific directions rather than broadcasting omnidirectionally. It is essential at mmWave and terahertz frequencies where signals are highly directional
