Aspects of the subject disclosure may include, receiving a plurality of communication signals, and generating, according to the plurality of communication signals, a plurality of electromagnetic waves bound at least in part to a dielectric layer environmentally formed on a conductor. The plurality of electromagnetic waves propagates along the dielectric layer of the conductor without an electrical return path, where each electromagnetic wave of the plurality of electromagnetic waves includes a different portions of the plurality of communication signals, and where the plurality of electromagnetic waves utilizes a signal multiplexing configuration that at least reduces an interference between the plurality of electromagnetic waves. Other embodiments are disclosed.
