Vehicle Mounted Modem (VMM) Deployment Consideration
Before defining a VMM configuration (mounting an AP7161 mesh point on a moving vehicle), refer
to the following deployment guidelines to ensure the configuration is optimally effective:
•
Disable layer 2 stateful packet inspection from the firewall policy.
•
Set the RTS threshold value to 1 on all mesh devices. The default value is 2347. For more
information on defining radio settings, see
Access Point Radio Configuration
•
Use Opportunistic as the rate selection settings the default is Standard. For more information
on defining this settings, see
Channel Width
Configure the channel width that mesh point automatic channel scan should assign to the
selected radio. The available options are:
•
Automatic – Indicates the channel width is calculated automatically. This is the default value.
•
20 MHz – Indicates the width between two adjacent channels is 20 MHz.
•
40 MHz – Indicates the width between two adjacent channels is 40 MHz.
Priority Meshpoint
Configure the mesh point to be monitored for automatic channel scan. This is the mesh point that
given priority over other available mesh points. When configured, a mesh is created with this mesh
point. When not configured, a mesh point is automatically selected.
Meshpoint: Path Minimum
Configure the minimum path metric value for a mesh connection. Set a value between 100 -
20,000.
Meshpoint: Path Metric
Threshold
Configure a minimum threshold value for triggering an automatic channel selection for mesh point
selection. Set a value in between 800 - 65535.
Meshpoint: Tolerance
Period
Configure the time duration in seconds to wait before triggering a automatic channel selection for
the next hop.
Meshpoint: Root Sample
Count
Configure the number of scans to be performed for data collection before a mesh point root is
selected. Set a value between 1 - 10 scans.
Meshpoint: Root
Off-channel Duration
Configure the duration in the range of 20 - 250 milliseconds for the Off Channel Duration field
when scanning for mesh point root. This is the duration that the scan dwells on each channel when
performing an off channel scan.
Meshpoint: Root Channel
Switch Delta
Configure the delta value in dBm in the range 5 - 35 dBm which when crossed triggers a mesh
point root automatic channel selection.
Meshpoint: Root
Off-channel Scan
Frequency
Configure the duration in seconds between two consecutive Off Channel Scans for mesh point
root. Set a duration between 1 - 60 seconds.
Meshpoint: Root Channel
Hold Time
Configure the minimum duration to stay on a selected channel before the channel conditions are
reassessed for a possible channel change for mesh point root. Set a value between 0 - 1440
minutes. Set this value to ‘Zero’ (0) to prevent a automatic channel selection from happening.
