Abstract

Aspects of the subject disclosure may include, for example, a system for transmitting signals by first electromagnetic waves guided by a first transmission medium, and, responsive to a determination of an undesired condition, adjusting the first electromagnetic waves to cause cross-medium coupling between the first transmission medium and a second transmission medium resulting in the signals being transmitted by second electromagnetic waves guided by the second transmission medium. Other embodiments are disclosed.

Claims

1. A method, comprising:

determining, by a system comprising a processor, an undesired condition associated with a first transmission medium, wherein signals are transmitted by first electromagnetic waves at a first physical interface that includes a first surface of the first transmission medium, wherein the first electromagnetic waves propagate without requiring an electrical return path, and wherein the first electromagnetic waves are guided by the first transmission medium; and

responsive to the determining the undesired condition, adjusting, by the system, the first electromagnetic waves to cause a cross-medium coupling between the first transmission medium and a second transmission medium resulting in the signals being transmitted by second electromagnetic waves at a second physical interface that includes a second surface of the second transmission medium, wherein the second electromagnetic waves propagate without requiring the electrical return path, and wherein the second electromagnetic waves are guided by the second transmission medium.

2. The method of claim 1, wherein the adjusting the first electromagnetic waves comprises increasing a wavelength of the first electromagnetic waves.

3. The method of claim 2, wherein the first and second transmission mediums are separated by a particular distance using a spacer, and wherein an amount of the increasing of the wavelength is based on the particular distance separating the first and second transmission mediums.

4. The method of claim 1, wherein the adjusting the first electromagnetic waves comprises polarizing the first electromagnetic waves.

5. The method of claim 1, further comprising increasing a transmit power associated with the first electromagnetic waves responsive to the determining the undesired condition.

6. The method of claim 1, further comprising increasing a transmit power associated with the second electromagnetic waves utilizing a repeater device coupled with the second transmission medium.

7. The method of claim 1, further comprising:

determining, by the system, that the undesired condition is no longer associated with the first transmission medium; and

responsive to the determining that the undesired condition is no longer associated with the first transmission medium, further adjusting, by the system, the first electromagnetic waves to cease the cross-medium coupling between the first transmission medium and the second transmission medium resulting in the signals no longer being transmitted by the second electromagnetic waves at the second physical interface.

8. The method of claim 7, wherein the further adjusting the first electromagnetic waves comprises decreasing a wavelength of the first electromagnetic waves.

9. The method of claim 1, wherein the determining the undesired condition associated with the first transmission medium comprises monitoring for electromagnetic wave reflections associated with the first transmission medium.
