Figure 193: Overlays Menu
The Overlays menu contains three common sections: Type, Floors, and Frequencies. Selecting options in the Type
section will display additional menu sections that affect the data overlays on the floor plan you are viewing. These
additional options appear between the Type and Floors sections.
Type section
Select one of the following types:
l Heatmap - Evaluate coverage based on signal levels by providing the highest dBm (energy level) for all areas of a
floor plan. When this option is selected, the Signal Cutoff drop-down menu displays. From this drop-down, you
can select a common cutoff value or you can specify a custom value.
l Speed - Evaluate coverage based on transmit power of client by providing the highest data rate a user will receive
for all areas of a floor plan. When this option is selected, the Client Transmit Power drop-down menu displays.
Use this drop-down to select a transmit power value for the overlay. Additionally, a Rates section appears
enabling you to select either 54Mbps, 300Mbps, and 450Mbps.
l Ch. Utilization - View how much airtime is used in the environment. Airtime usage is a good measure of how
busy an area is. When you select this option, a new Data Set menu appears where you can select the Current or
Maximum Total, Receive, Transmit, or Interference information to display on the floor plan.
l Sensor Coverage - Provides the farthest area which a sensor can hear. When this option is selected, the Client
Transmit Power drop-down menu displays. Use this drop-down to select a transmit power value for the overlay.
l Voice - Provides color-coded overlay based on number of radios covering each grid cell based on the selected
signal cutoff. When this option is selected, the Signal Cutoff drop-down menu displays. From this drop-down,
you can select a common cutoff value or you can specify a custom value.
