Purpose and goal
This project explores the use of sub-THz frequency range for Low-Earth Orbit (LEO) satellite networks. The project utilizes a synergy of design approaches, theoretical tools, and simulation models toward developing the most efficient configuration of the satellite network when utilizing sub-THz radios. To achieve this goal, the project team unites experts in sub-THz physical layer design, satellite communications, and efficient networking approaches from Sweden, the USA, and Singapore.
Expected effects and result
Relevant channel and physical layer study, end-to-end link budget analysis; identifying the most promising sub-THz radio configurations to be used for satellite networks. End-to-end performance study of sub-THz satellite network vs. mmWave and optical solutions.
Planned approach and implementation
The project structure consists of three major work packages (WPs). WP1 on the physical layer is led by KTH (PI). WP2 on medium access control and networking is led by the team at Singapore University of Technology and Design (SUTD, international collaborator). WP3 on testing and validation is led by the team at Northeastern University, Boston, MA, USA (NU, international collaborator). The partners strive to work together, coordinate their activities toward the common key project goals.
