Applying Visualizations

Data analysis for predictive models is very similar to data analysis for passive surveys; it is described in detail in the Analyzing Data – Passive Surveys and Predictive Models chapter. In brief, you simply need to select a visualization from the drop-down list on the toolbar. However, in case of predictive models, you can also control the Visualization quality by using the corresponding control on the tool bar. Visualization quality is an important parameter that defines how precise the calculations are. High-precision calculations come at a cost: the higher the precision, the longer the computation time. The application offers four quality presets: Low, Medium, Good, and Best. They differ in grid size and in applying advanced RF propagation effects, such as reflection and Fresnel zones. We suggest that you use low or medium visualization quality while you design your WLAN and make adjustments to your design. When the design is ready, you can use good or best visualization quality for the final verification and/or report generation.

IMPORTANT: Calculating RF propagation is a very CPU-intensive task that might take a long time for large floor plans with many APs. It is recommended that you use a fast multi-core CPU, such as Intel i7, because in this case the application could take advantage of parallel computations that are possible on multi-core CPUs. It is also recommended that you split large floor plans into smaller parts if computing visualizations takes too long.
