The invention provides, in some aspects, an improved control network (or portion thereof) that includes a plurality of nodes, each associated with respective control devices (e.g., controllers, actuators, sensors, etc.). Each of the nodes also includes one or more radios supporting wireless communications pathways with one or more of the other nodes, which pathways together form at least part of a mesh network. At least a first one of the nodes wirelessly transmits information simultaneously, or substantially simultaneously, over at least two pathways formed in a mesh network to a second one of the nodes. The radio(s) of the first node, according to related aspects of the invention, sends that information wirelessly at different frequencies along each of those pathways.
