Bar Graph Display Mode

This display mode shows the percentage of utilization

for all channels within a selected frequency band in

the form of a bar graph.

• The horizontal axis (left/right) of the graph

represents the individual channels within the

selected frequency band.

• The bar graph of the currently selected channel

will be displayed in shades of purple, while all

other channels will appear in shades of green.

• The vertical axis (up/down) of the graph

represents the total percentage of utilization for

the channel within the 2.4 GHz frequency band.

• The graph displays a maximum level of

100% (top of graph) and minimum level

of 0% (bottom of graph).

• Each column within the graph will appear

in shades of either green or purple.

• Each horizontal bar within a column of the

graph represents approximately 5% utilization

and is color coded as follows:

• Horizontal bars of these darker colors correspond to the measurement

value displayed by the 802.11 Usage eld. When present, these darker

bars will always appear at the bottom of the column.

• Horizontal bars of these lighter colors correspond to the measurement

value displayed by the non-802.11 Usage eld. When darker bars are

present, the lighter bars will be placed at the top of the column.

• Horizontal bars in blue always appear at the top of the column and

represent the maximum total percentage of utilization that was

recorded during the sampling period.

• When the display mode is set to 5 GHz Channels, use the Band softkey to toggle

between the three different 5 GHz wireless frequency bands.
