In addition to the surveys based on actual on-site measurements, TamoGraph can be used for planning WLANs that have not been deployed yet. This type of survey is called ‘predictive’ or ‘virtual’, because Wi-Fi characteristics are predicted for the virtual environment model created by the user. The process of creating and adjusting the virtual environment, selection and placement of simulated APs, and analysis of the resulting WLAN is commonly referred to as ‘RF planning’.

To create a virtual model of the environment, the user needs to ‘tell’ the application about the position, size, and type of the physical objects that affect radio wave propagation.
