Table 4.2 – Use of rf-1 and rf-2 configurations
Topology Node type rf-1 rf-2
Point-to-
Multipoint hub Link with children Not used
remote Link with parent Link with parent (if
roaming is enabled)
Tree
root-1 Link with children Not used
root-2 Link with children Link with children
branch Link with parent Link with children
leaf Link with parent Link with parent (if
roaming is enabled)
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 in each rf-1 and rf-2 configurations (see roam command below). Separate channel
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.
See Table 4.3 below for the valid channel numbers.
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). See table 4.3 below for the
valid channel numbers.
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. 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 (see table 4.3 below). 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.
Example:
> rf1 ant=a rec=15 tra=15 po=27 sp=0.5
