How energy-efficient is O-RAN compared with conventional RAN architectures?
Our research, published in IEEE Transactions on Green Communications and Networking, introduces a parametric power consumption model and a DU/CU placement methodology evaluated using real-world network datasets from France (42,797 RUs) and Ireland (10,198 RUs).
The findings reveal that O-RAN is not inherently more energy-efficient. Energy consumption depends strongly on network topology, placement constraints, and processing characteristics, highlighting the importance of energy-aware design for future mobile infrastructures.
🌱 Can 5G become greener? The O-RAN sustainability challenge!
Discover how Radio Units (RUs), Distributed Units (DUs), and Centralized Units (CUs) shape the energy footprint of next-generation mobile networks. Through manga-inspired storytelling, we explore how intelligent network planning and power consumption modeling can help pave the way toward sustainable 5G and beyond.
⚡ The challenge isn't just making networks smarter. It's making them greener!
