Abstract
When planning cellular networks, the goal is to position antennas and adjust their parameters to maximize the coverage and minimize the interference between antennas. In new generations of cellular networks like 5G, network planning is becoming critical due to the use of high frequencies and the densification of the network. Antenna locations are typically decided based on the availability of cellular towers, however, tunable parameters, like tilt and transmission power, determine the network capacity and the quality of service. To optimize the network and compute coverage and interference for different tilt and power values, radio propagation is simulated using ray tracing over a geospatial model of the environment. In this paper, we present a ray-tracing module that computes long-distance effects of cellular transmissions, to accurately model interference between remote antennas. The two main novelties are (1) the computation of diffraction to include non-line-of-sight propagation, and (2) parallel computation for efficiency and scalability. The demonstration presents the geospatial effect of diffraction on the computation and the use of GPUs for scalability while avoiding race condition in the transformation from a polar coordinate system to a Cartesian representation.
