The paper Open RAN testbeds with controlled air mobility, recently accepted for publication in Elsevier Computer Communications, explores the requirements for experimental demonstration and verification of facilities to study O-RAN wireless and autonomous UASs jointly. We look at over 25 testbed facilities in the light of these requirements, including our own AERPAW. The paper is published as part of the “Large-scale Experimental Platforms for Computer and Networking Research: Recent Advances and Challenges” Special Issue, which will be available in print in December 2024. The paper is available for free download here till November 13th, 2024.
