1. A system, comprising:
- means for receiving a wireless signal from a communication device;
means for converting the wireless signal to an electrical signal;
means for frequency-shifting the electrical signal to generate a frequency-shifted signal; and
means for generating a transmission of the frequency-shifted signal to induce, via a coupling device, an electromagnetic wave guided by a transmission medium, wherein the coupling device has a central axis that is not coaxially aligned with a longitudinal axis of the transmission medium, and wherein a portion of the coupling device is parallel to a surface of the transmission medium.

Abstract
Aspects of the subject disclosure may include, for example, a system including a frequency mixer that combines a signal and a carrier wave to form a combined signal, and a transmitter that generates a transmission based on the combined signal. The system can also include a coupling device that emits the transmission as an electromagnetic wave guided by an outer surface of a transmission medium. The electromagnetic wave can propagate longitudinally along the surface of the transmission medium and at least partially around the surface of the transmission medium. Other embodiments are disclosed.
