3Gbps Wireless Demoed in Japan

Megan Geuss reporting … Terahertz frequencies bring Japanese researchers 3Gbps in a WiFi prototype

:

The terahertz wireless radio is small enough to fit in portable devices.

A team of researchers at the Tokyo Institute of Technology have transmitted data on the terahertz range of spectrum using a wireless radio no bigger than a 10-yen coin (roughly the size of a penny). The tiny contraption can access spectrum between 300GHz and 3Tbps (otherwise known as T-Rays for terahertz), and was able to transfer data at a speed of 3Gbps. But this was only a test run—researchers suspect that using terahertz spectrum could get data transfer up to rates of 100 Gbps.
