Abstract: Aspects of the subject disclosure may include, for example, receiving, by a network element of a distributed antenna system, a reference signal, a control channel and a first modulated signal at a first carrier frequency, the first modulated signal including first communications data provided by a base station and directed to a mobile communication device. The instructions in the control channel direct the network element of the distributed antenna system to convert the first modulated signal at the first carrier frequency to the first modulated signal in a first spectral segment. The reference signal is received at an in-band frequency relative to the control channel. Other embodiments are disclosed.

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 transmission medium for propagating electromagnetic waves. The transmission medium can have a first dielectric material for propagating electromagnetic waves guided by the first dielectric material, and a second dielectric material disposed on at least a portion of an outer surface of the first dielectric material for reducing an exposure of the electromagnetic waves to an environment that adversely affects propagation of the electromagnetic waves on the first dielectric material. 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 send 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, a transmission system having a coupling device, a bypass circuit, a memory and a processor. The coupling device can facilitate transmission or reception of electromagnetic waves that propagate along a surface of a transmission medium. The memory can store instructions, which when executed by the processor, causes the processor to perform operations including restarting a timer to prevent the bypass circuit from disabling the transmission or reception of electromagnetic waves by the coupling device. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a system including a frequency mixer that combines a signal and a carrier wave to form a combined signal, and a transmitter that generates a transmission based on the combined signal. The system can also include a coupling device that emits the transmission as an electromagnetic wave guided by an outer surface of a transmission medium. The electromagnetic wave can propagate longitudinally along the surface of the transmission medium and at least partially around the surface of the transmission medium.
