WifiSurveyor
WifiSurveyor examines each Wi-Fi channel in three complementary ways: network discovery, RF spectrum analysis, and active channel-performance measurement.
Hardware and bands
WifiSurveyor uses the appliance radios for discovery and performance testing and an attached RF Explorer for spectrum measurement. A band is available only when the active RF Explorer radio covers it.
- 2.4 GHz — channels 1–11.
- 5 GHz — supported non-DFS channels in the 36–48 and 149–165 groups.
On a multi-radio RF Explorer, select the required radio module on the device.
Access-point controls
The table lists SSID, BSSID, signal, channel, and security for nearby access points. Select a row to include or exclude that access point from the charts. Select All, Deselect All, and Show Hidden provide bulk controls.
The four synchronized charts
Site Survey
Shows discovered access points as signal “mountains” centered on their Wi-Fi channels.
RF Spectrum Waterfall
Shows the strongest RF energy measured in each channel over time. It includes Wi-Fi and non-Wi-Fi energy. The appliance briefly quiets the performance radio before capturing spectrum data.
Channel Performance Score
Shows the achieved transmit rate for each channel. Bar height and color represent the normalized 0–100 score; the value above the bar is Mbps.
Performance Over Time
Records the channel scores from completed sweeps so changing conditions are visible.
Interpreting the evidence
The views share a channel axis but answer different questions:
- Discovery shows which Wi-Fi networks are present.
- Spectrum analysis shows how much RF energy is present, including sources a Wi-Fi scan cannot name.
- Performance testing shows how effectively the radio actually transmitted.
Do not assume that many access points, high RF energy, and poor performance always occur together.
