1. A system, comprising:

  • a first waveguide system coupled to a first transmission medium, wherein the first waveguide system facilitates reception of first electromagnetic waves that propagate along a first surface of the first transmission medium, wherein the first electromagnetic waves include first data, and wherein the first transmission medium corresponds to a primary communication link;

    a second waveguide system coupled to a second transmission medium, wherein the second waveguide system facilitates reception of second electromagnetic waves that propagate along a second surface of the second transmission medium, wherein the second waveguide system is configurable to transport in the second electromagnetic waves at least a portion of the first data transported in the first electromagnetic waves when a fault is detected that adversely affects a propagation of the first electromagnetic waves along the first surface of the first transmission medium, and wherein the second transmission medium corresponds to a secondary communication link;

    an antenna coupled to the first waveguide system and the second waveguide system;

    a processing system including a processor; and

    a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, comprising;

    detecting the fault in the primary communication link;

    responsive to detecting the fault, switching to the secondary communication link for reception of the second electromagnetic waves;

    receiving the second electromagnetic waves from the secondary communication link; and

    generating, by the antenna, a wireless signal based on the second electromagnetic waves received from the secondary communication link.
