Path Method SNR

Use the Path Method SNR screen to set a profile's mesh point channel width, mesh point priority and signal to noise (SNR) scan settings.

To define a profile's path method signal to noise ratio:

1. Select the Configuration tab from the Web UI.

2. Select Profiles from the Configuration tab.

3. Select Manage Profiles from the Configuration > Profiles menu.

4. Select Mesh Point.

   Refer to the Mesh Point screen to view existing Mesh Points. If an existing Mesh Point configuration does not meet your requirements, select the Add button to create a new mesh point configuration or the Edit button to modify the parameters of an existing mesh point configuration. The Mesh Point screen displays the Settings tab by default.

5. Select the Auto Channel Selection tab.

6. Select the Path Method SNR tab.

7. Set the following values (common to both 2.4 GHZ and 5.0/4.9 GHz):

   Channel Width	Set the channel width the meshpoint's automatic channel scan assigns to the selected radio. Available options include: Automatic – Defines the channel width is calculated 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. 80 MHz - Sets the width between two adjacent channels as 80 MHz for 802.11ac access points.
   Priority Meshpoint	Configure 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.

8. Select OK to save the updates to the Mesh Point's path method SNR configuration. Select Reset to revert to the last saved configuration.
