THz Communication Technology in India Present and Future

As the communication industry is currently undergoing a major overhaul to accommodate greater bandwidth and higher data-rate to meet the rapidly growing data demand; terahertz range of frequencies from 100 GHz to 3 THz are being investigated as a possible replacement of the conventional mm-wave technology. In this paper, we have examined the technology readiness of Indian research community in this specific direction and have discussed the research development strategies that are required to gain momentum towards achieving a viable technology standard in THz communication in India. Moreover, we have presented a collection of technology recommendations towards product development required for initiation and advancement in THz communication. We have also introduced a design of a short-range THz communication configuration in conclusion, based on recent reports of successful realization of THz communication which could be utilized for immediate realization using commercially available resources
