About Me

I am an engineer by heart and passionate about making srsRAN the most reliable and trusted enterprise 5G stack on earth.

Over the past years, I’ve worked on various 4G/5G/xG-related projects, both as active developer, leading engineer and/or project manager.

Prior to helping to build srsLTE/srsRAN, I was working as a postdoctoral researcher at Trinity College Dublin, Ireland and Ilmenau University of Technology, Germany.

I am involved in open-source software development for over two decades.

Panel - Challenges and solutions for energy efficiency in Open RAN

Next-generation networks promise revolutionary capabilities, including ultra-low latency, high data rates, and ubiquitous connectivity. However, these goals can only be achieved by improving network capacity, reliability, and latency, which in turn requires using larger bandwidth and especially a tenfold to hundredfold increase in the number of mobile access points. Improving energy efficiency becomes of paramount importance to keep this growth sustainable, as the Radio Access Network (RAN) uses 70-80% of the total energy consumption of cellular networks. Energy needs to be saved both horizontally (end-to-end from user to cloud) and vertically across all levels, from hardware chips to infrastructure deployments and software. In virtualized RANs, energy efficiency need to be developed across the different components at the RU, in the DU and CU implementation, making use of hardware acceleration and use of low power states in the general purpose processors; in the implementation of energy-efficient schedulers; and in the orchestration of the RAN cloud. In addition, ORAN brings the additional challenge of coordinating and synchronizing these energy-saving approaches. This session brings together vendors involved in the development of different parts of the ORAN chain to discuss current challenges and possible solutions ahead.
