Main View

Device Displays the device name, MAC and IP Address of

the device running AirView.

Total RF Frames Displays the total number of RF frames

gathered for as long as AirView has been running or since

the “Reset All Data” button was pressed.

FPS Indicates the total number of frames gathered per

second. The wider the interval amplitude, the fewer frames

per second will be gathered.

Reset All Data Press this button to reset all gathered data.

Use this function when you want to analyze the spectrum

for another place or address.

View

Enable Chart Panel 1 (top) Enable this option to display

the top chart, Waterfall or Channel Usage, depending

on which you have selected in Preferences. These are

time-based graphs showing the aggregate energy

collected or Channel Usage over time for each frequency

for as long as AirView has been running.

Enable Chart Panel 2 (middle) Enable this option to

display the middle chart, Waveform. This a time-based

graph showing the aggregate energy collected for each

frequency over time. The color of the energy designates

its amplitude: colder colors stand for lower energy

levels (with blue representing the lowest levels) at that

frequency bin, whereas warmer colors (like yellow, orange

or red) mean higher energy levels at that frequency bin.

Enable Chart Panel 3 (bottom) When enabled, this graph

displays a traditional Spectrum Analyzer in which energy

(in dBm) is shown in real-time as a function of frequency.

Clear All Markers Press to reset all previously assigned

markers. Markers are assigned by clicking a point, which

corresponds with a frequency, on the third chart.

Preferences In this section you can modify AirView

Settings, such as enabling or disabling charts, or

specifying the frequency interval.

Preferences

Charts

Enable Top Chart Select the chart to be displayed in the

top chart on the main view. There are two options:

• Waterfall This is a time-based graph showing the

aggregate energy collected over time for each

frequency while AirView has been running. The color of

energy designates its amplitude. Colder colors stand for

lower energy levels (with blue representing the lowest

levels) at that frequency bin, whereas warmer colors

(like yellow, orange or red) mean higher energy levels at

that frequency bin.

The Waterfall View’s legend (top-right corner) provides a

numerical guide associating the various colors to power

levels (dBm). The low end of that legend (left) is always

adjusted to the calculated noise floor, and the high end

(right) is set to the highest detected power level since

the start of the session.

•

Channel Usage In this graph, each 2.4GHz Wi-Fi

channel is represented by a bar displaying a percentage

showing the relative “crowdedness” of that specific

channel. This percentage is calculated by analyzing both

the popularity and the strength of RF energy in that

channel since the start of an AirView session.

Enable Waveform chart (middle) Like the Waterfall

chart, this a time-based graph showing the aggregate

energy collected for each frequency over time while

AirView has been running. The color of the energy

designates its amplitude: colder colors stand for lower

energy levels (with blue representing the lowest levels)

at that frequency bin, whereas warmer colors (like

yellow, orange or red) mean higher energy levels at that

frequency bin.

The spectral view over time will essentially display the

steady-state RF energy signature of a given environment.
