Adjusting AP Locations

When you have performed a 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. Correcting the location may improve data analysis quality in the areas located far from the walkabout path. 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 AP that is currently highlighted in the AP list). To remove an AP completely, drag and drop it outside the map area. Doing so 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.
