Energy efficiency has become a high-priority target for all operators, both to meet net-zero emissions and to reduce opex, at the very same time they are moving to more open networks, with virtualization and disaggregation.
In this conversation with Rob Hughes, Head of Wireless Marketing at Fujitsu Network Communications, we talked about how energy efficiency and openness will fundamentally jointly change the RAN and strengthen each other.
An open, disaggregated and virtual RAN will give operators more choices to deploy more energy-efficient networks and benefit from the latest innovation in power management.
