Scientists in Pisa, Italy claim to have set a new world record for the fastest wireless data transmission. They report that during an uninterrupted 12-hour experiment, they were able to achieve throughput speeds above 1.2 Terabits per second; which they say beats the previous wireless data transmission speed record of 160 Gigabits per second by Korean scientists. The researchers claim that speeds of this magnitude can typically only be achieved using fiber optics.
The technology that the Pisa scientists utilized to achieve such high bandwidth, actually shares a significant similarity with fiber optics: Both technologies use optical communications. Unlike Wi-Fi or microwave communications, which use radio-based transmissions, the Pisa scientists used a Technology called free-space optical communications, which transmits data using light. The Harvard Broadband Communication Laboratory provides this explanation of Free-Space Optical Communications[…]
