Researchers from the Tokyo Institute of Technology in Japan have successfully developed hardware capable of transmitting data 20 times faster than current Wi-Fi speeds using a portion of the electromagnetic spectrum between 300 GHz and 3 THz known as the “T-ray” band.
Using a resonant tunneling diode, researchers were able to generate signals at frequencies up to 542 GHz by tuning the current in the device to produce smaller voltages. The development may lead to the commercial development of extremely fast Wi-Fi networks in the near future.
