Annual Report 2021: Helsinki Distinguished Lecture Series on Future Information Technology
HIIT is the organiser of the Helsinki Distinguished Lecture Series on Future Information Technology. The focus of this lecture series is on the research challenges and solutions faced by current and future information technology, as seen by internationally leading experts in the field. The lectures are intended to be approachable for people with scientific education in fields other than information technology, whilst at the same time providing information technology experts new viewpoints to their own discipline. The series was launched in 2012, and in 2021 we had only one event, due to the corona virus situation.
A New CubeSat Design with Reconfigurable Multi-band Radios for Dynamic Spectrum Access in Internet of Space Things
Small satellites, or CubeSats, are envisioned as a promising solution for future satellite communication networks because of their low costs and short deployment cycle. Currently, CubeSats communicate at conventionally allocated satellite communication frequencies. However, with the increase in the number of CubeSats, CubeSat-enabled communication systems, and many new use cases, new spectrum bands and a more efficient spectrum usage are needed. In this talk, a novel CubeSat design with reconfigurable multi-band radios for communication in dynamic frequencies is proposed. The multi-band radio design is realized by two complementary approaches, namely, an electronics-based and a photonics-based approach. The multi-band communication covers a wide range from radio frequencies (2–30 GHz), millimeter wave (30–300 GHz), Terahertz band (up to 10 THz), and optical frequencies (with typical bands of 850 nm/350 THz, 1300 nm/230 THz, and 1550 nm/193 THz). A thorough link budget analysis is conducted to demonstrate the potential of the proposed multi-band architecture for space information networks. Key parameters in the satellite constellation design are investigated to explore the feasibility of deployment at different altitudes in the exosphere orbit (500 km and above). Furthermore, software-defined networking (SDN), and network function virtualization (NFV) have been incorporated to effectively separate the abstraction of functionalities from the hardware by decoupling the data forwarding plane from the control plane, such separation is of prime importance given the limited onboard processing on CubeSats. Additionally, key parameters in the constellation design including the coverage footprint and number of CubeSats as well as orbital planes, etc. are investigated for feasibility and deployment studies at different altitudes in the exosphere orbit.
