Design Considerations for Terahertz Wireless Communication Systems

Current trends in the evolution of mobile communication systems address the data throughput demand by expanding to higher frequency bands as the usable spectrum in lower frequency bands is almost depleted. As the Third Generation Partnership Project (3GPP) specified the support of mmWave band operations for 5G New Radio (NR), it is expected that the next generation mobile communication system, namely 6G, will consider even higher terahertz (THz) spectrum with wider bandwidth to continue supporting exponential growth of data rates. However, the question remains how to deal with various technical challenges stemming from harsh THz radio propagation characteristics as well as the feasibility of radio frequency (RF) components, which we try to answer in this work. To this end, it is our goal to demonstrate the promise of THz spectrum for the next generation communication systems.
