Over the last few years, wireless data traffic has drastically increased due to a change in the way today’s society creates, shares and consumes information. In parallel to the massive growth in the total number of mobile connected devices, there has been an increasing demand for higher speed wireless communication anywhere, anytime. Wireless data rates have doubled every eighteen months for the last three decades. Following this trend, Terabit-per-second (Tbps) links will become a reality within the next five years.
In this context, Terahertz (THz)-band (0.1–10 THz) communication is envisioned as a key wireless technology to satisfy such demand. This frequency band, which lies in between millimeter-waves and the far infrared, remains still one of the least explored regions in the EM spectrum. For many decades, the lack of compact high-power signal sources and high-sensitivity detectors able to work at room temperature has hampered the use of the THz band for any application beyond sensing. However, many recent advancements with different electronic, photonic and plasmonic technologies is finally closing the so-called THz gap.
THz-band communication brings many new opportunities to the wireless communication community. The THz band supports huge transmission bandwidths, which range from almost 10 THz for distances below one meter, to multiple transmission windows with bandwidth of tens to hundreds of GHz, for distances in the order of a few tens of meters. The THz band opens the door to a plethora of applications in very diverse domains, ranging from Terabit Wireless Personal and Local Area Networks to Wireless Nanosensor Networks or the Internet of Nano-Things. Nevertheless, there are many challenges from the device, communication and networking perspectives, which require fundamentally new solutions.
The First IEEE International Workshop on Terahertz Band Communication Networks (TBCN) will be held in Shanghai, China, on May 2019, in conjunction with the IEEE International Conference on Communications (ICC). The twofold mission of this workshop is to increase the visibility of THz communications and to bring together researchers from diverse disciplines that can foster and develop this very fast developing field. The workshop aims to attract researchers and academics from various fields of study, ranging from THz materials, devices and packaging, to THz communication and networking researchers.
