The Open RAN Market is Rapidly Expanding


Open Radio Access Network (RAN) is not a new technology, but an innovative implementation approach promoting more open, transparent, and modular cellular networks and ecosystems. It invites various stakeholders to bring their best-in-class technologies and contribute to building the next-generation telecommunications networks, including 5G. These very same principles have shaped many industries that have now become the growth engine of our economy, including the Internet, the Personal Computer (PC) business, and the smartphone market. The ABI Research white paper Open RAN: Market Reality and Misconceptions discusses the importance of both hardware and software to allow this leap in terms of performance and efficiency in Open RAN network implementations.

Current Open RAN market developments have largely focused on the Centralized Unit (CU) and Distributed Unit (DU), which take advantage of existing processing platforms and new software to process what was traditionally processed in baseband units. This is Layer 2 and Layer 3 functionality, complemented by what is called …
