A new record for terahertz transmission [News]

Engineers achieve amazing data rates in a once-inaccessible band. The problem with the radio spectrum between 3 and 3000 megahertz is that it?s crowded. Television, radio, mobile phones, Bluetooth, GPS, two-way communication devices, and Wi-Fi all operate in this high- to ultrahigh-frequency range. So with nowhere to go but up, researchers have been working for decades to utilize the 3- to 3000-gigahertz span. In October, a team reported a hopeful sign-a record 100-gigabit-per-second wireless data transmission.
