Cerento - Modelling the impact of wind farms on MW networks

May 25, 2023

Engineering services company Cerento turned to HTZ Communications to resolve an interference problem resulting from a nearby wind turbine. They used HTZ Communications to evaluate the impact on their network services and identify mitigation solutions.

Cerento operate a PTMP network in the 3GHz band and fixed services in the 6GHz and 11GHz bands. They ran a coexistence analysis’ across all the services, leveraging HTZ’s internal libraries of royalty-free map data and propagation models. By importing all the Gateways and subscriber locations into HTZ, they automatically modelled the PTMP network based on the best signal level considering terrain, clutter and building layers. This study looked at all the possible connections and threshold/KTBF levels. The wind turbine RCS was calculated automatically considering the threshold degradation (TD) values based on the shape and surface of the mast and blades.

Brandon Shears, Engineering Manager at Cerento said, “HTZ can model any technology from a few kHz to 1THz. Its built-in PTMP features allowed us to simulate potential interference from the turbine into MW links in the 3GHz band and generate a CSV file with the results. The analysis was exported and overlaid on Google Earth to present to our end customer. It was simple to use and provided accurate results.”
