The Platforms for Advanced Wireless Research (PAWR) program of large-scale wireless testbeds, which was created and initially funded by the U.S. National Science Foundation, have gained O-RAN ALLIANCE approval as Open Testing and Integration Centers (OTICs). These include:
- POWDER at the University of Utah – POWDER supports end-to-end Open RAN testing in lab and field scenarios and has developed a Testing Orchestration and Testing Automation (TOTA) framework to provide streamlined, on-demand testing capabilities. O-RAN ALLIANCE defined OTIC services provided by POWDER will include interoperability and end-to-end testing, badging and certification. POWDER will offer additional Open RAN related services including use case and proof-of-concept development and evaluation, functional testing in lab and field environments, and Open RAN intelligent ecosystem research, testing and development.
- ARA at Iowa State University – ARA enables research into connectivity solutions for rural environments, including offering a heterogeneous set of access network technologies to support innovative Open RAN testing and development for digital agriculture, rural education, and more. As an OTIC, ARA will support Open RAN R&D, device-level and end-to-end testing of performance, interoperability, and conformance in both sandbox and at-scale field settings.
- Colosseum as part of the Institute for the WIoT at Northeastern University – The Northeastern team is using the Colosseum infrastructure, which is affiliated with the PAWR program, and other assets of the Institute’s Open 6G Hub to provide testing capabilities for end-to-end AI and ML solutions that will enable new Open RAN use cases. Through its OTIC, Northeastern will provide testing, certification, and badging capabilities.
“By becoming OTICs, the PAWR testbeds are advancing important innovations in wireless research from the academic community and beyond and helping to bridge the gap between government investment and industry-driven change,” said Margaret Martonosi, NSF Assistant Director for Computer and information Science and Engineering. “Wireless communications are vital to both the public and private sectors, and through the services these platforms will provide as OTICs, the PAWR testbeds will accelerate the timeline that begins with cutting-edge research and leads to successful deployment of new wireless technologies.”
