The O-RAN ALLIANCE has been supporting the testing and integration needs of its member companies for the past several years through the development of test specifications, specifying processes for certification and badging, establishment of Open Test and Integration Centers, and organizing Global PlugFests. A previous white paper has provided an overview of the certification and badging process and Open Test and Integration Centers. This white paper dives deeper into the O-RAN test specifications and other Open RAN laboratories that are contributing towards the proliferation of Open RAN. In addition, the paper contributors have outlined key challenges in Open RAN and recommendations on how to overcome several of these challenges.
