separate 802.11 and non-802.11 Utilization and shows
only a combined total Utilization.
Figure 13. Combined Channel Utilization
Signal Level: T
he real-time signal level (in dBm) of the
strongest AP signal on the channel.
Noise: The measured real-time noise level.
SNR: The measured real-time signal-to-noise ratio.
Refresh: Tap this icon to clear the current results and
restart channel scanning.
Capture: Tap this button to open the Capture screen and
start a packet capture on the selected channel. See “Creating
a Standalone Packet Capture,” page 97.
The Channels Overlap Screen
The Channels Overlap screen displays a graphical
representation of the discovered APs' utilization of each
channel. This screen displays in landscape view. Channel
numbers are on the x-axis, and the signal level in dBm is
displayed on the y-axis of the graph.
Tap the tab buttons across the top of the graph to display the
different bands and corresponding channels:
• 2.4 GHz — Channels 1-14
• 5 GHz UNII-1/2 —
Channels 36-64 (not including 34,
38, 42, or 46)
• 5 GHz UNII-2 Ext — Channels
100-144
• 5 GHz UNII-3 — C
hannels 149-165
A colored parabola is shown on the graph for each active
Access Point the AirCheck G2 detects.
Tap an AP's parabola, and then its popped-up name, to open
the corresponding AP Details screen.
