Terahertz (THz)
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. Major engineering challenges include power amplifier efficiency, atmospheric absorption, and the need for extremely precise beamforming.

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
mmWave
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
