Siemens and Hrvatski Telekom have finalized the White Space Cooling Optimization (WSCO) project for HT's data center in Zagreb. The initiative employs an intelligent sensor layout and AI-based cooling control to enhance operational efficiency and sustainability.

WSCO integrates technical components such as wireless sensors, control modules, and an AI engine, along with a user interface. It operates through a continuous optimization loop that analyzes data from thermistors measuring temperature changes on servers and network racks.

The AI system autonomously regulates fan airflow, dynamically adjusting cooling processes to eliminate up to 99% of hot spots. Additionally, the solution enhances preventive maintenance by detecting faulty components.
