Abstract: Aspects of the subject disclosure may include, for example, a transceiver that converts first modulated channel signals in a first spectral segment to the first modulated channel signals in a second spectral segment based on signal processing of the first modulated channel signals and without modifying the signaling protocol of the first modulated channel signals. The transceiver transmits, via a fiber optic cable, a transmission signal including a first reference signal with the first modulated channel signals in the second spectral segment to a network element of a plurality of network elements of the distributed antenna system for wireless distribution of the first modulated channel signals to mobile communication devices in the first spectral segment. The first reference signal enables the distributed antenna system to reduce a phase error during processing of the first modulated channel signals from the second spectral segment to the first spectral segment.

Abstract: Aspects of the subject disclosure may include, for example, a launcher that includes a hollow waveguide that guides a first electromagnetic wave conveying data from a transmitting device. A dielectric stub coupler receives the first electromagnetic wave from the hollow waveguide to form a second electromagnetic wave that propagates along a portion of the dielectric stub coupler adjacent to a transmission medium, wherein second electromagnetic wave propagates along the dielectric stub coupler via a first guided wave mode and a second guided wave mode, and wherein the portion has a length that supports a coupling of the second guided wave mode for propagation along an outer surface of the transmission medium.
