OpenAirX-Labs (OAX) A lab ecosystem incubated within Institute for Wireless Internet of Things @Northeastern University Part of the Platforms for Advanced Wireless Research (PAWR) program Funded by NSF and the U.S. Department of Defense's Office of the UnderSecretary of Defense for Research and Engineering [DOD OUSD (R&E)] Supported by OSA board as the official North American Designate AffiliateDevelopment Partner
Memberships and PartnersOAX is an activeparticipant in thefollowing opensource ecosystemsOAX has severalindustry andacademic partners
OpenAirX-Labs Charter North American home for development, testing and integration ofOpenAirInterface 5G SA software stack. Provide a benchmark, end-to-end 5G Standalone reference architecture topromote innovation Central Point of Contact for testing and evaluation status across member labpartners. Provide development and test status for SA features Continuous Integration (CI) system to accelerate the development and testing ofthe software stack. Promote stable, compliant and performant stack

3. Worker job initiates Colosseum pipeline on server 2 (oai -ci-server-mgmt.colosseum.net) 4. Ansible toolchain builds OAI and create LXC containers 5. Containers and config files are pushed to Colosseum 6. Ansible module initiates a Colosseum batch reservation 7. Colosseum resource manager assigns resources for the job 8.
