In this paper, we present a fast algorithm based on a ray-tracing technique with scalable approximation accuracy for field strength prediction in cellular mobile network planning together with a preprocessing of the geographical database. Automatic network design methods perform a huge number of field strength estimations and, therefore, require a fast and accurate approximation. However, common prediction techniques either give only rough estimations or are too complex for fast evaluation. The proposed new ray-tracing technique obtains its speedup by taking advantage of the topological information inherent in the used triangulation data structure of the investigated terrain. The applicability of the fast ray-tracing technique is demonstrated for a single transmitter scenario.

Abstract
In this paper, we present a fast algorithm based on a ray-tracing technique with scalable approximation accuracy for field strength prediction in cellular mobile network planning together with a preprocessing of the geographical database. Automatic network design methods perform a huge number of field strength estimations and, therefore, require a fast and accurate approximation. However, common prediction techniques either give only rough estimations or are too complex for fast evaluation. The proposed new ray-tracing technique obtains its speedup by taking advantage of the topological information inherent in the used triangulation data structure of the investigated terrain. The applicability of the fast ray-tracing technique is demonstrated for a single transmitter scenario.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
