An integrated circuit for use in a wireless management system with a primary node and secondary nodes includes: a wireless transceiver; and a wireless management controller included with or coupled to the wireless transceiver. The wireless management controller is configured to: identify a first secondary node of the secondary nodes in communication with the primary node; identify a second secondary node of the secondary nodes not in communication with the primary node; and enable the first secondary node to operate as a proxy node that repeats downlink messages to or uplink messages from the second secondary node.
