Abstract

Aspects of the subject disclosure may include, for example, a system for detecting an accumulation of a liquid on a transmission medium that may interfere with the propagation of guided electromagnetic waves on a surface of the transmission medium, and directing a device to remove at least a portion of the liquid accumulating on the surface of the transmission medium to mitigate the interference. Other embodiments are disclosed.

Claims
