Antenna: In most topologies use antenna A for the RF configuration 1, and antenna B for the
RF configuration 2. This is not mandatory, there are situations when you may want to override
this default.
Receive-channel: For the link with the parent this value must match the transmit channel of
the desired parent. If you have the roaming option enabled you can specify up to six receive
channels for the rf-1 configuration (separate values with commas but no spaces). These
channels should match the transmit channels of separate access points in the area (hub, root or
branch). The radio will then attach to the parent with the strongest signal and change parent
automatically when the signal becomes too weak.
Transmit-channel: This is only applicable at the parent nodes for the links with their children.
At the child nodes, the transmit channel is configured automatically when the node attaches to
the parent (it will be set to match the receive channel of the parent).
Power-dbm: This is the transmit power fed into the antenna. The default value is 18 dBm
which is adequate in most situations. If you do not have enough link margin or there is
interference in your channel you may want to increase the power up to the maximum value
aupported by your model. If your links are very short and you have plenty of signal you can
reduce the transmit power in order to re-use the same channel in other links in the area.
Speed-mbps: This is only applicable at the parent nodes for the links with their children. At
the child nodes the speed is set automatically to match that of the parent. The default value is
always the highest speed supported by your specific model. The lower speeds may be
appropriate for very long links where the receive signal strength is too weak and you need a
little more link margin. We suggest that in those cases you first increase the transmit power
and only then start reducing the speed.
