TROUBLESHOOTING
POOR/LOW
THROUGHPUT
RF INTERFER-
ENCE
1. As a general rule of thumb, if there is no RF
interference and nodes are in proximity to
each other, a 20MHz channel should observe
approximately 20Mbps throughput, a 10MHz
channel should observe approximately
10Mbps, and a 5MHz channel should observe
approximately 5Mbps.
2. If low throughput is measured, test other
center frequencies until you achieve the
highest throughput possible for a given
channel width.
3. Resolve interference issue with other
transmitter located nearby.
MAX LINK
DISTANCE SET
INCORRECTLY
1. If Max Link Distance is set incorrectly and/or
inconsistently in a network, throughput will be
affected negatively. To set Max Link Distance
correctly, determine the farthest distance any
individual link on this frequency may need to
be, then choose the next longest Max Link
Distance. e.g. 13 mi = Max Link Distance
should be set to 15 mi. To set Max Link
Distance, click “Node Configuration” > “Node
Configuration.”
CHANNEL DEN-
SITY SET INCOR-
RECTLY
1. If Channel Density is set incorrectly and/
or inconsistently in a network, throughput
will be affected negatively. To set Channel
Density, click “Node Configuration” > “Node
Configuration.” Channel Density should be
set by the number of nodes in the network.
BLADE ANTEN-
NA DOES NOT
HAVE A GOOD
(METALLIC)
GROUND PLANE
1. Install a proper metallic ground plane.
POOR AUDIO MICROPHONE
VOLTAGE NOT
ENABLED (MPU3
AND QUAD
ONLY)
1. Microphone voltage must be enabled for use
with certain headsets.
2. To enable microphone voltage, click “Node
Configuration” > “PTT Configuration” > “Ac-
cessory Features.”
MICROPHONE
GAIN NOT SET
TO AUTO
1. To set microphone gain to auto, click “Node
Configuration” > “PTT Configuration” > “Mi-
crophone Level” > enter “auto” into the field.
