| Home Screenshots WifiEagle Here |
Below are sample screenshots from WifiEagle. They are divided into two categories: Channel Analysis and 802.11 Network Discovery. The data acquired and analyzed for channel analysis uses the wireless device that was shipped with the WifiEagle product, while the data displayed for 802.11 network discovery (i.e. Wi-Fi Scanning) uses your built-in 802.11 wireless adapter.

Statistics
Grid Description: For each channel, reports several properties of the % Maximal Throughput -- the current value, an averaged value, a high and low value (obtained from the average and standard deviation), the standard deviation, and the elapsed time since this session began. |

Channel
Heatmap
Chart Description: Also known as a "waterfall" graph. It is a 3-dimensional representation of the data, where channels are marked along the X-axis, the Y-axis is a time scale and indicates the last 60 scans or sweeps, and the "Z-axis" is the color scale. Each horizontal line in the Heatmap chart displays the % Maximal Throughput (as a color) for each channel measured over the time period of one scan. |

Channel
Spectrogram Chart
Description: Shows a similar result as the Channel Timecourse chart, but in 3-dimensions. The Channel Spectrogram view is a 3D plot of 802.11 channels as a function of time. Each channel is represented by its own set of bar graphs -- the Z-axis is time and the Y-axis is % Maximal Throughput. |

Channel
Timecourse Chart Description: The Channel Timecourse view is useful for monitoring channels as a function of time. Each channel is represented by a different line -- the x-axis is time and the y-axis is % Maximal Throughput. |

Channel
Statistical
Chart Description: Shows an averaged value of % Maximal Throughput for each channel since the program was first launched (the horizontal red bar), along with its associated standard deviation. |
|
Channel
Differentials Chart Description: The gray bars are a snapshot of the % Maximal Throughput values when the program was first launched, the green bars are the current values, and the blue bars represent the difference. |
|
Channel Topographic Chart Description: Similar to a 3-D histogram, the topographic chart (above) shows how frequently certain % Maximal Throughput values occur for each channel. The more frequently a particular value is measured for a channel, then the color gradually changes from blue, to green, to yellow and ultimately red. |

Grid of Access
Points Description: This grid of local access points is updated in (semi) realtime -- that is, scans are performed approximately once every 5 seconds. |
|
Timecourse of
Beacon Qualities For Each Access Point Description: This chart displays the beacon strength of each access point as a function of time. The Y-axis reports the signal strength as a signal quality (0 - 100%) -- where a maximum signal is assumed to be -20 dBm and the dissociation signal is -85 dBm (http://www.ces.clemson.edu/linux/dbm-rssi.shtml). |
|
Differential
Display of Beacon Qualities For Each Access Point Description: This chart displays the current beacon strength of each access point compared with an earlier snapshot. The current beacon strength is displayed in purple, the snapshot in light-blue, and the difference in olive green. |

Usage of Each
of the 802.11 b/g Channels Description: This chart combines the access points by channel and displays a summary of channel usage. As in most of the other charts, the Y-axis reports the signal strength of beacons as a signal quality (0 - 100%). In this view the data for each channel represents a collection of access points -- hence the signal quality as displayed along the Y-axis is often greater than 100%. This is because we are summing the signal qualities for each of the access points that use a particular channel. |

Heatmap Chart
of the 802.11 b/g Channels Description: This chart combines the access points by channel and displays a summary of channel usage as a Heatmap. The Heatmap chart is also known as a "waterfall" graph. It is a 3-dimensional representation of the data, where the X-axis is the channel, the Y-axis is a time scale, and the "Z-axis" is the beacon signal quality that uses color scale. Each horizontal line in the Heatmap chart displays beacon signal strength (as a color) as a function of channel as measured over the time period of one scan. That is, with each scan (or sweep) a new row is added at the bottom of the Heatmap chart. The color legend to the right shows that stronger signals will appear red and weaker signals will appear blue. |
