Hiroshima University, the National Institute of Information and Communications Technology, and Panasonic Corporation announced the development of a terahertz (THz) transmitter capable of signal transmission at a per-channel data rate of over ten gigabits per second over multiple channels at around 300 GHz. The aggregate multi-channel data rate exceeds one hundred gigabits per second. The transmitter was implemented as a silicon CMOS integrated circuit, which would have a great advantage for commercialization and consumer use.
This technology could open a new frontier in wireless communication with data rates ten times higher than current technology allows.
Details of the technology were presented at the “International Solid-State Circuit Conference (ISSCC) 2016,” held from January 31 to February 4 in San Francisco, California.
The THz band is a new and vast frequency resource not currently exploited for wireless communications. Its frequencies are even higher than those used by the millimeter-wave wireless local area network (from 57 GHz to 66 GHz), and the available bandwidths are much wider.
Since the speed of a wireless link is proportional to the bandwidth in use, THz is ideally suited to ultrahigh-speed communications.
