The research objective of the TeraNets project is to establish the theoretical foundations of ultra-broadband communication networks in the terahertz (THz) Band. New channel models for the entire THz Band will be developed. These will account for line-of-sight, non-line-of-sight and multi-path propagation and will capture the peculiarities of molecular absorption and scattering from rough surfaces. Bandwidth-adaptive modulations to exploit the distance-dependent behavior of the bandwidth at THz Band frequencies will be developed. In addition, massive MIMO transmission schemes to increase the communication distance and novel channel coding approaches to efficiently overcome channel errors at THz Band frequencies are to be investigated. Finally, novel Medium Access Control protocols for THz Band communication networks are proposed, which capture the peculiarities of the physical layer and take advantage of large antenna arrays and dielectric mirrors.The TeraNets project is expected to pave the way for research in communication networks in the THz Band. Ultra-broadband communication networks will play a major role in society within the next ten years by drastically increasing the capacity of wireless networks, and enabling long-awaited applications not possible with current wireless technologies. In addition, the THz Band is not yet regulated. The project team is actively involved in IEEE 802.15 WPAN Terahertz Interest Group (IGThz), whose objective is to create the first standard for this paradigm. The research results will be incorporated into the Information and Network Theory and Wireless Communication and Networks within the School of Electrical and Computer Engineering, at the Georgia Institute of Technology, both at undergraduate and graduate levels. This, combined with grauate student resarch mentoring, will produce new experts in this nascent field. The research results will be disseminated in important scientific conferences, journals and premier magazines of the field.

TeraNets项目的研究目标是为太赫兹(THz)频段的超宽带通信网络奠定理论基础。将为整个太赫兹频段开发新的信道模型。这将解释视线、非视线和多路径传播，并将捕捉分子从粗糙表面吸收和散射的特性。将开发带宽自适应调制，以利用太赫兹频段带宽的距离相关行为。此外，增加通信距离的大规模MIMO传输方案和有效克服太赫兹频段信道差错的新颖的信道编码方法也将被研究。最后，提出了一种新的太赫兹频段通信网络介质访问控制协议，该协议抓住了物理层的特点，利用了大型天线阵和介质反射镜，为太赫兹频段通信网络的研究奠定了基础。超宽带通信网络将在未来十年内在社会上发挥重要作用，它将大幅增加无线网络的容量，并实现人们期待已久的应用，而目前的无线技术无法实现这些应用。此外，太赫兹频段尚未受到监管。该项目团队积极参与IEEE 802.15 WPAN太赫兹兴趣小组(IGTHZ)，该小组的目标是为该范例创建第一个标准。研究成果将纳入佐治亚理工学院电气和计算机工程学院的信息与网络理论和无线通信与网络，包括本科生和研究生。这一点与研究生研究指导相结合，将在这个新兴领域培养出新的专家。研究成果将在该领域的重要科学会议、期刊和主要杂志上传播。
