One of the most frequent questions that come up when talking about energy efficiency is whether Open RAN will make the RAN consume more or less power than traditional RAN for the same performance.
Alex Choi, Senior Vice President at Deutsche Telekom and Chairman at the O-RAN Alliance, and Gorden Witzel, Senior Partner Manager, Vendor Strategy Access at Deutsche Telekom, discussed this topic at great length during a Sparring Partners.
Energy efficiency in Open RAN is a complex issue because it is not just about the impact of open interfaces and disaggregation but also about the role of virtualization, distributed versus centralized topologies and chipsets. And energy efficiency depends on how the network is deployed, and its traffic load and distribution. Alex and Gorden present Open RAN as a toolkit for operators to increase network efficiency: it creates opportunities but does not guarantee a specific outcome.
