Rain Attenuation Characterization for 6G Terahertz Wireless Communication

High bandwidth, high speed data rate, and low latency are the demand of wireless connectivity over few decades. The demand is increasing and will be very high in near future. Terahertz (THz) frequency band (275 GHz to 3 THz) have some powerful characteristics to satisfy the demand through establishing ultra-high speed link. Existing millimeter wave (mm wave) has incapability of meeting high data rate with huge bandwidth for sixth generation (6G) communication systems. Though a terahertz link has a noticeable impact of weather condition, however, the powerful resources and minimization of attenuation by using high directional antenna opens the promising door for future use. In this paper, we show different losses, terahertz application, a brief comparison between mm wave and terahertz and we simulate the rain attenuation characteristics of terahertz link. To address this issue, this paper provides different field of application, its different losses and attenuation profile for rainy weather thus help to open the new door for the ultra-high speed world.
