The <strong>Distance</strong> setting adjusts the packet retry timer
to account for stations that are very far away, presumably about 300 meters or
more. The value should be set to the distance in meters to the farthest node
that you expect to communicate with. Change the distance value by moving the slider. Distance values will be in multiples of 1000 meters (approximately 0.62 miles). A value of zero is not allowed.
The <strong>Distance</strong> setting adjusts the RF retry timer
to define how long the transmitter will wait for an acknowledgement
from a Neighbor station. If the distance parameter is too short, then
the transmitter will send duplicate data packets before the acknowledgement
has had time to return. This value is only applicable to nodes that can
be communicated with directly over RF and not multiple hop nodes on the
greater mesh network. The value should be set to the distance in meters
to the farthest direct RF node you expect to communicate with. Change
the distance value by moving the slider. Distance values will be in multiples
of 1000 meters (approximately 0.62 miles). A value of zero is not allowed.
The best way to test an optimal distance settings is to do an 'iperf'
test directly between 2 nodes to measure the performance of this RF
channel. Try different distance settings to peak out the iperf thoughput.
