The Wireless Spectrum (PDF) is insane to look at. For the amount of communication we conduct it just isn’t enough. While the chart only goes up to 300 GHz it shows near the bottom that the Terahertz Band is in the Infrared range. Which is much faster than Microwaves. Imagine your Wi-Fi traveling extremely fast with this technology.
According to AllThingsD,
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.
Even though the article said its not going to replace Wi-Fi, I’m very hopeful. Now I think I’ll stare at the wireless spectrum again.
