11. Set the following 2.4 GHz and 5.0/4.9 GHz path method SNR data:
12. Select the Path Method Root Path Metric tab to calculate root path metrics.
Channel Width Set the channel width the meshpoint automatic channel scan assigns to the selected radio.
Available options include:
•
Automatic – Defines the channel width calculation automatically. This is the default value.
•
20 MHz – Sets the width between two adjacent channels as 20 MHz.
•
40 MHz – Sets the width between two adjacent channels as 40 MHz.
Priority Meshpoint Set the meshpoint monitored for automatic channel scans. This is the meshpoint assigned priority
over other available mesh points. When configured, a mesh connection is established with this
mesh point. If not configured, a meshpoint is automatically selected. This setting is disabled by
default.
SNR Delta Set the signal to noise (SNR) ratio delta (from 1 - 100 dB) for mesh path selections.
When path selection occurs, the defined value is utilized for selecting the optimal path. A better
candidate, on a different channel, must have a signal strength that exceeds this delta value when
compared to the signal strength of the next hop in the mesh network. The default setting is 5 dB.
SNR Threshold Set the SNR threshold for mesh path selections (from -100 to 0 dB).
If the signal strength of the next mesh hop falls below this set value, a scan is triggered to select a
better next hop. the default setting is -65 dB.
Off-channel Duration Configure the duration (from 20 - 250 milliseconds) for scan dwells on each channel, when
performing an off channel scan. The default setting is 50 milliseconds.
