5G Infrastruktura: Inženjering monopola za nordijske vjetrove
Inženjerski izazovi za 5G monopole u skandinavskim uvjetima. Otpornost na vjetar >250 km/h i ISO certifikacija.
The 5G Infrastructure Challenge
The European 5G rollout demands thousands of new cell tower installations across Scandinavia, the Baltics, and Central Europe. Polygonal steel monopoles are the preferred solution for urban and suburban deployments due to their aesthetic profile and structural efficiency.
However, Nordic conditions present extreme engineering challenges: wind loads exceeding 250 km/h, heavy ice accumulation, and temperature ranges from -40°C to +35°C.
