4.6.5 Configuration of Radio 1 Frequencies
Proper configuration of Radio 1 hailing channel is required in order for the nodes to connect.
Configure radio 1 (on both primary and secondary nodes) with DL (downlink) and UL (uplink)

On the primary node, the term “Downlink” refers to the radio transmitter, whereas on the
secondary node the “Downlink” configuration applies to the radio receiver.
Use of the terms “Downlink” and “Uplink” (instead of “transmit” and “receive”) means both nodes
Use of the terms “Downlink” and “Uplink” (instead of “transmit” and “receive”) means both nodes
share the same frequency configuration making it easier to compare configurations or switch roles.
Both primary and secondary nodes must have the same configuration for Radio 1 DL and UL
Both primary and secondary nodes must have the same configuration for Radio 1 DL and UL
frequencies in order for the link to connect. Radio 1 frequency configuration is referred to as the
“hailing channel”, and serves as the starting point whenever either node restarts, or the link fails for

any reason. If Dynamic Channel Selection is enabled (DCS described in a subsequent section) radio

1 will potentially move to alternate frequencies after its started. However the link will always start
with radio 1 on the hailing channel. If DCS is disabled, then of course Radio 1 will remain on the
hailing channel.
Unless you are working around a specific known interference issue at one location, its reasonable to
use a single frequency for both DL and UL.
