Potential of THz Broadband Systems for Joint Communication, Radar, and Sensing Applications in 6G

The potential of broadband THz communication system is not limited to extremely high data rate transmissions up to several TBit/s. Rather, the true application potential of THz systems will be created by the combination of the communication and radar/sensor functionality under the use of the enormous available bandwidth with partially more than 10 GHz. This enables to develop new applications in the areas of 3D imaging radar systems, sensor systems, car‐to‐car communication in combination with car radar, and security application like private alarm system via Wi‐Fi router. The reuse of future standard 3GPP and IEEE802 THz technology will allow the implementation of low‐cost THz communication systems, which enable the joint use of THz systems as a high‐resolution sensor systems, which optimize themselves by the use of artificial intelligence to provide never‐before‐achieved resolutions for radar and sensor applications additional to high‐speed Tbit/s data transmissions.
