Abstract
The introduction of Open RAN represents the biggest shift in radio access architecture we have seen during the last two decades. Promotors claim it comes with great promise such as lower costs, scalability, faster and greater innovation, unprecedented flexibility and shorter lead times for deployment of new services. On the other hand, its opponents question whether the cost savings are real, raise concerns of increased complexity as well as network disruptions risks. In this white paper we try to answer these questions, build on our previous papers as well as our own technology research and development, and our discussions with operators around the globe.
