Like almost everything in Telecom’s, Open RAN is complicated. It’s not a single idea. It’s not a single product or service. It’s not an optimization technique or path towards improved efficiency.
Heck, it’s hardly even an agreed term. You’ll find references in the literature to OpenRAN, Open RAN (my preference), ORAN, and O-RAN. I’m not aware that there is a commonly accepted term. I prefer the term Open RAN and will use that throughout this article.
But whatever it’s called, it’s easy to grasp.
OpenRAN is essentially 2 foundational ideas:
- The disaggregation of network functionality from the underlying hardware. In other words, software-defined functionality.
- The specification of discrete functional blocks having well-defined interfaces. In other words, modularity.
These ideas are both pretty simple.Continue reading “What is Open RAN?”
