High Speed Wireless Transmission System at 190–320 GHz Band

The development of technology in the field of wireless communication is very rapid. It is predicted that the wireless transmission rates will reach several Terabits per second (Tbps) in the next few years. Currently, terhertz band (0.1-10 THz) communication channel is being developed to achieve a transmission rate of Tbps. Many applications in wireless communication require very high transmission rates, such as: autonomous vehicles while driving at high speeds, back-haul in 5G or 6G cellular networks, HD holographic video conferencing, and so on. Terahertz channel is characterized as very high path loss so that the suitable for short distance applications, i.e., only a few tens of meters. In this research, we investigated the communication performance at the operating frequency 190– 320 GHz sub-terahertz in term of channel capacity to determine the maximum transmission rate can be achieved and the image quality at the receiver for uncompressed image transmission applications. The results show that the transmission rate can reach speeds of 1 Tbps for distances less than 10 m and the quality of the received image is the same as transmitted image while the transmission is less than 2 m.
