This Huawei whitepaper presents the Green Sky Program, focused on making antennas more energy-efficient, sustainable, and adaptable. Antennas play a critical role in reducing base station power use and emissions. Green innovations target three areas: energy saving (improving antenna & feeder efficiency by 40%), green deployment (simplifying installation, halving site boxes, modular and reconfigurable designs), and green manufacturing (cutting plastics, PCBs, soldering, and electroplating, while using cleaner processes like laser welding). Architectural, process, and form innovations—such as SDIF architecture, modular antennas, and A+P integration—are central to meeting 2025 targets.
