5G is the latest standard for mobile networks. The technology enables higher speedsthrough the use of higher frequencies. These higher frequencies mean shorter range forsignals. Consequently, the placement of connection points becomes increasingly crucialto achieve optimal performance. By simulating how connection points should be placedinstead of having a person manually test different placements, both time and money canbe saved. The client already has a simulator in place that supports visualizing whethera receiver is reached by a radio beam or not. The simulator consists of two parts, whereone simulates the behavior of radio beams using ray tracing, and the other displays theresults of the simulation. The goal of this work is to extend the existing simulator withfeatures to simulate and visualize signal attenuation in radio beams. The simulationtakes place in a ray tracing engine that utilizes the OptiX ray tracing API. Unity isused for visualization to graphically depict how the power of radio beams changes. Toachieve this goal, enhancements to the existing simulator were made, and investigationsinto ray tracing, signal attenuation, and electromagnetic properties were conducted. Theresult of the work is an extension of the simulator with the capability to visualize thedecreasing power of radio beams using different colors. Additionally, the user interfacewas expanded with features to make the simulator easier to use.
