Abstract

Aspects of the subject disclosure may include, for example, a method that includes extracting first channel signals from first guided electromagnetic waves bound to an outer surface of a transmission medium of a guided wave communication system; amplifying the first channel signals to generate amplified first channel signals in accordance with a phase correction; selecting one or more of the amplified first channel signals to wirelessly transmit to at least one client device via an antenna; and guiding the amplified first channel signals to the transmission medium of the guided wave communication system to propagate as second guided electromagnetic waves, wherein the phase correction aligns a phase of the second guided electromagnetic waves to add in-phase with a residual portion of the first guided electromagnetic waves that continues propagation along the transmission medium.
