In accordance with one or more embodiments, a system can include a plurality of twisted insulated conductors, and a communication device coupled to a first conductive endpoint of each insulated conductor of the plurality of twisted insulated conductors. The communication device can facilitate generating transmission signals at each first conductive endpoint of each insulated conductor of the plurality of twisted insulated conductors. The transmission signals in turn can induce electromagnetic waves that propagate along interstitial areas between the plurality of twisted insulated conductors. Other embodiments are disclosed.
