Scientists in Italy Set Wireless Network Speed Record

A team of Scientists in Pisa, Italy are reported to have set a new world record in wireless data transmission speed. Italian researchers from Sant’Anna University along with the Japanese Waseda University and the National Institute of Information and communication technology in Tokyo, for the “first time in the history of telecommunications” achieved throughput speeds of above 1.2 Terabits per second. Previous record, set in Korea, had been160 Gigabits per second.

The technology used in the experiment is known as free-space optical communications which the Harvard Broadband Communications Laboratory defines as:

“Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of light, operating in the TeraHertz portion of the spectrum, are focused on a receiving lens connected to a high sensitivity receiver through an optical fiber.”
