Parallel approach for prediction of radio wave propagation in urban scenarios


Prediction of radio wave propagation in urban scenarios plays an important role for planning and optimizing wireless cellular networks. For network planing a huge amount of configurations, and therefore predictions, are needed. A prediction which takes an hour or more to calculate, the time ray tracing approaches often need, is not suitable. There are prediction models which are much faster on the cost of accuracy. This work is looking out for these faster approaches and carries them over to parallel hardware. The hardware trend is showing towards systems with many small cores. These cores have strongly limited memory. This is a challenge because of the size of the geometric building descriptions.

Concepts for simplifying and handling the building descriptions are introduced. And an outline for a prediction model based on ray launching is given.
