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.

Abstract: Aspects of the subject disclosure may include, for example, a network termination includes a downstream channel modulator modulates downstream data into downstream channel signals to convey the downstream data via a guided electromagnetic wave that is bound to a transmission medium of a guided wave communication system. A host interface sends the downstream channel signals to the guided wave communication system and receives upstream channel signals corresponding to upstream frequency channels from the guided wave communication system. An upstream channel demodulator demodulates upstream channel signals into upstream data. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a repeater device having a first coupler to extract downstream channel signals from first guided electromagnetic waves bound to a transmission medium of a guided wave communication system. An amplifier amplifies the downstream channel signals to generate amplified downstream channel signals. A channel selection filter selects one or more of the amplified downstream channel signals to wirelessly transmit to the at least one client device via an antenna. A second coupler guides the amplified downstream channel signals to the transmission medium of the guided wave communication system to propagate as second guided electromagnetic waves. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a host node device having a terminal interface that receives downstream channel signals from a communication network and sends upstream channel signals to the communication network. An access point repeater launches the downstream channel signals as guided electromagnetic waves on a guided wave communication system and to extract a first subset of the upstream channel signals from the guided wave communication system. A radio wirelessly transmits the downstream channel signals to at least one client node device and to wirelessly receive a second subset of the upstream channel signals from the at least one client node device. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, an antenna structure that includes first and second dielectric antennas that each redirect a beam pattern generated by the first and second dielectric antennas away from a center axis of the of the first and second dielectric antennas. Each of the first and second dielectric antennas can be coupled to at least one dielectric core via a feed point of each dielectric antenna. The at least one dielectric core can be configured to supply electromagnetic waves that are converted by the first and second dielectric antennas to first and second beam patterns redirected away from the center axis. Other embodiments are disclosed.
