Adjusting AP Locations After Passive Surveys

When you have performed a passive site survey, TamoGraph will automatically place APs on the site map. The location of APs is estimated based on the collected data. Location estimates may not always be accurate due to the complex nature of radio wave propagation, but you can correct them by dragging the AP icon to the correct location with a mouse.

The effect that the AP icon locations have on the calculations of the signal level and other visualizations depends on the How AP icon locations affect signal setting that you can find on the Visualization Settings panel (located on the Options tab of the right-side panel.) By default, Estimated AP locations are used to complement measured signals (new algorithm), which means that correcting the location may improve the quality of data analysis in the areas located far from the walkabout path. This is recommended for most surveys. If you select Estimated AP locations do not affect signal levels; they are icons only, the application displays data based ONLY on the actual measurements; there are no extrapolations. This is suitable for the surveys where signal levels are low and AP locations cannot be estimated accurately. Finally, you may want to select Estimated AP locations are used to complement measured signals (old algorithm, up to version 4.1). This option exists solely for providing compatibility with the TamoGraph versions prior to 4.2; the result might be overly optimistic.

If you corrected the AP location(s) by moving the corresponding icon(s), you can revert to the original location by right-clicking on the AP list on the left panel and then clicking Auto-locate Access Points (this action can be applied to All or Selected APs; here by Selected, we mean the APs that are checked in the AP list). To remove an AP completely, drag and drop it outside the map area or use the Clear Access Point Locations command (again, this action can be applied to All or Selected APs; here, by Selected, we mean the APs that are currently checked in the AP list). Removing an AP from the site map means that the AP location becomes undetermined, which, in turn, means that, for this AP, no data extrapolation is performed, and only the actual signal readings are used.

Displaying AP locations is an optional feature. Additionally, by default, TamoGraph does not attempt to estimate the locations of those APs for which the signal level is low. The AP Detection and Placement panel (located on the Options tab of the right-side panel) can be used for configuring these features.

When an AP is placed on the site map (either automatically or by the user), this is indicated on the left panel by a small plus (+) sign in the lower right corner of the AP icon. If an AP was not automatically placed on the map and you want to place it there, you can drag the AP icon from the AP list to the site map. To remove it from the site map, drag the AP icon outside of it.
