Terahertz-Band Communications for Ultra-High-Speed Wireless Links
Quick fact
Terahertz waves can carry more than 100 gigabits per second over short distances—that’s roughly 10 times faster than current 5G peak speeds—but they are absorbed by water vapor in the air, making them travel only tens of meters.
Why this is interesting
Your phone downloads a movie in seconds over Wi‑Fi, but what if you could do that 100 times faster? The terahertz band might hold the key—yet it's so finicky that even the air gets in the way.
