The following settings affect the way TamoGraph displays some of the visualizations:
Area is considered covered if signal strength is at least – This setting defines the AP coverage area based on the minimum signal strength. If the signal strength is below the specified level, the area is considered to be not covered, which means that some data values will not be computed for the area (such areas will appear as white spots). The definition of “strong enough” is rather subjective because certain signal strength might be sufficient for low data rates, but insufficient for the high data rates required for such applications as VoIP. Additionally, 802.11 adapters vary in sensitivity, and some adapters might be able to provide good connectivity in zones where other adapters fail to connect altogether. The default value is -70 dBm. This setting is applicable to the following visualizations: Signal-to-Interference Ratio, AP Coverage Areas, and Number of APs.
Average network utilization – This setting defines how heavy the interference is from the interfering APs. If the interfering signal strength is high, but the network utilization is low, the interfering AP does not create much interference. A typical office WLAN has a network utilization of between 10% and 25%. Adjust this setting to match the actual value for your WLAN. This setting is applicable to the following visualization: Signal-to-Interference Ratio.
AP coverage areas – This setting allows you to change the color coding method used for displaying coverage areas. In No fill, contours only mode, the application draws contours of the coverage areas without filling the areas with colors. In Fill and mix colors mode, the AP coverage areas are filled with colors; when areas overlap, the application draws a striped pattern, alternating the colors of the respective APs. In Fill, strongest AP on top mode, AP coverage areas are filled with colors; when areas overlap, the application draws the color of the strongest AP. In Fill, weakest AP on top mode, AP coverage areas are filled with colors; when areas overlap, the application draws the color of the weakest AP. This setting is applicable to the following visualization: AP Coverage Areas.
