Channel there means AMQP 0-9-1 channel.

AMQP 0-9-1 connection involves a TCP connection, user authentication
and one or more channels over which protocol methods are sent and received.

Right, this is what federated queues are about:

Note that you can also publish messages over one protocol (say, MQTT)
and consume them using another protocol (AMQP 0-9-1 or STOMP). There
are some limitations to this because protocol features don’t necessarily
match but for the proverbial 80% of cases it should work well.
