1. A system of a machine, the system comprising:
a first node and a second node configured to establish a first communication path through a waveguide system to guide a radio frequency transmission between the first node and the second node in the machine;
a third node and a fourth node configured to establish a second communication path in the machine, wherein the first node is grouped with the third node as a first node group, and the second node is grouped with the fourth node as a second node group such that the second communication path provides a redundant communication path with respect to the first communication path for communication between the first node group and the second node group, wherein the first communication path comprises a first waveguide and the second communication path comprises a second waveguide physically separated from the first waveguide; and
a shared communication path is configured to merge at least one portion of the first communication path and the second communication path between the first node group and the second node group, wherein the shared communication path is coupled to both the first waveguide and the second waveguide.
