Wireless industry’s newest gambit: terahertz communication bands
The terahertz band (0.3 THz to 10 THz) is the next frontier in wireless communications for its ability to unlock significantly wider segments of unused bandwidth. Though radio channels above 100 GHz are little known, several high-speed terahertz communication links have been demonstrated in recent years. … The research team at NYU Wireless has carried out penetration measurements at the 140 GHz band for various building materials. That includes drywall, clear glass, and glass doors. Here, the average penetration loss of clear glass has been 3.2 dB/cm at 28 GHz, while it amounted to 14 dB/cm at 140 GHz, showing how the penetration loss increases with frequencies.
