Future smart factories are expected to deploy emerging dynamic Virtual Reality (VR) applications with high bandwidth wireless connections in the THz communication bands, where a factory worker can follow activities through 360° video streams with high quality resolution. THz communications are however known for low fault tolerance and high sensitivity to external factors, resulting in low throughput. To address this challenge, a system is needed that can adaptively react to changing channel states by configuring THz transceivers in terms of coding and modulation. We propose a control plane that can help us configure the THz communication system adaptively. The control plane implements a workflow algorithm to choose between various coding and modulation schemes depending on THz channel states. The results show that an adaptive control plane can improve throughput and signal resolution quality, with theoretically zeroed bit error probability and a maximum achievable throughput in the scenarios analyzed.
