New Terahertz Wireless Connection Faster Than Your Microwave Oven

With the lower-frequency bands of the wireless spectrum becoming increasingly more crowded, scientists are searching out new swathes of spectrum over which to transmit our data. Among the most promising of those: The terahertz band, a completely unregulated range that lies somewhere between the microwave and infrared regions of the spectrum.

Typically, transmitting data across this band has required large, power-hungry equipment. But now researchers in Japan have managed to do it with far less complex equipment, and in doing so, have broken the terahertz wireless-transmission speed record.

Using a device called a resonant tunneling diode, Tokyo University researchers were able to achieve a 3 gigabits-per-second data transmission over the terahertz band — double the speed of the previous record set back in November by chipmaker Rohm.

Truly an impressive speed, though, as is often the case with advanced technologies like these, it comes with a caveat. The connection over which the data is transmitted is only good over distances of about 30 feet. So it’s not really an outright replacement for Wi-Fi. That said, there are plenty of short-range applications for which it would be perfect — transmitting media among home entertainment devices, backing up a PC to a wireless hard drive, etc.

Just as the atom bomb was the weapon that was supposed to render war obsolete, the Internet seems like capitalism’s ultimate feat of self-destructive genius, an economic doomsday device rendering it impossible for anyone to ever make a profit off anything again. It’s especially hopeless for those whose work is easily digitized and accessed free of charge.
