AirView - Spectrum Analyzer
AirView - Charts Preferences
AirView is a Spectrum Analyzer included in AirOS V5.3, allowing you to see the
crowdedness of the radio spectrum. A detailed step-to-step guide explaining
how to use AirView is available here (http://www.ubnt.com
/wiki/index.php?title=Best_channel_using_airview) .
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. For detailed information read bellow.
Clear All Markers: Press this button to reset all the previously assigned markers. Markers are assigned by clicking a point, which
corresponds a frequency, on the third chart.
Main View
Device: shows 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.
Preferences
In this section you can modify AirView Settings, such as to enable or disable
charts, or specify the frequency interval.
Charts
Enable top chart: Select the chart to be displayed in the top chart on the
main view. There are two options: Waterfall or Channel Usage.
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 (or 5GHz for M5-serie
devices) 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.
Enable Real-time chart (bottom): this graph displays a traditional Spectrum Analyzer in which energy (in dBm) is shown in real
time as a function of frequency. There are three traces in this view: Max Hold - this trace will update and hold maximum power levels
