Terahertz wireless data communication

Abstract

In recent years Terahertz (THz) Band communications have gained even greater interest and higher expectations to meet an ever increasing demand for the speed of wireless communications. This paper provides the characteristics of electromagnetic waves propagating in the THz Band, which is one of the key technology to satisfy the increasing demand for Terahertz Wireless Data Communication (ThWDC). The performance of future terabit super channels implemented using bipolar phase-shift-keying which gives the best BER (Bit Error Rate) with today's technology is investigated through the simulations for ThWDC. The objective of this paper is to describe the important issues related to the transmission in of ThWDC in air environment and to determine the best transmission windows in the THz range. In particular, ThWDC channel is modeled considering effects like capacity, channel performance and BER is investigated through simulation. The simulation results and the theoretical analysis show that data communication is possible from 0.01 to 0.5 THz frequency range and the best transmission window in this range have been found ý1 = [0.01---0.05 THz], ý2 = [0.06---0.16 THz] and ý3 = [0.2---0.3 THz] in this paper.
