OpenSAS: Open-Source Spectrum Access System

OpenSAS: Open-Source Spectrum Access System

As part of my research at the Commonwealth Cyber Initiative xG wireless testbed at Virginia Tech, I have been working on OpenSAS, an in-house open-source Spectrum Access System. This project focuses on enabling spectrum-sharing experiments and advancing the capabilities of dynamic spectrum access technologies.

Project Highlights

• Developed and implemented an open-source Spectrum Access System (SAS) for CBRS band
• Conducted spectrum-sharing experiments to evaluate performance and efficiency
• Integrated AI/ML-based incumbent detection capabilities
• Enabled SAS-SAS communication between multiple OpenSAS instances
• Created a flexible platform for research and experimentation in spectrum sharing

Impact

This project has contributed to the advancement of spectrum sharing technologies, which are critical for efficient use of limited spectrum resources. The open-source nature of OpenSAS allows other researchers to build upon our work and further advance the field.
