The objective of this research is to develop the first network architecture and protocol stack to support ultra-broadband airborne networks in the THz band 0.110 THz, by following a bottom-up approach and through a closed-loop combination of mathematical modeling, numerical simulation and experimental evaluation. During this period, contributions have been made along two thrusts. First, the development of the Ultra-Broadband Networking Systems Testbed, i.e., state-of-the-art platform to test the performance and refine the networking solutions to be developed as part of this effort has been significantly advanced. Initial functionalities, including successful data transmission and reception with single-carrier modulations following a time-division multiplex, have been demonstrated. Second, the concept of hierarchical bandwidth modulation, which can make the most out of the distance-dependent bandwidth of the THz channel resulting from molecular absorption by water, which on its turn changes across altitudes, has been proposed. The modulator and demodulator blocks have been designed, and the achievable performance has been numerically investigated. The outcomes of this project will contribute to realize the vision of the Air Force Future Operating Concept, and are well aligned with the NIST report on Future Generation Wireless Research and Development Gap.
