Aspects of the subject disclosure may include, for example, receiving, by a feed point of a dielectric antenna, electromagnetic waves from a dielectric core coupled to the feed point without an electrical return path, where at least a portion of the dielectric antenna comprises a conductive surface, directing, by the feed point, the electromagnetic waves to a proximal portion of the dielectric antenna, and radiating, via an aperture of the dielectric antenna, a wireless signal responsive to the electromagnetic waves being received at the aperture. Other embodiments are disclosed.

Method and apparatus for coupling an antenna to a device

A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

Remote distributed antenna system

Aspects of the subject disclosure may include, for example, a device that facilitates transmitting electromagnetic waves along a surface of a wire that facilitates delivery of electric energy to devices, and sensing a condition that is adverse to the electromagnetic waves propagating along the surface of the wire. Other embodiments are disclosed.

Method and apparatus for sensing a condition in a transmission medium of electromagnetic waves

Aspects of the subject disclosure may include, for example, a system for detecting a fault in a first wire of a power grid that affects a transmission or reception of electromagnetic waves that transport data and that propagate along a surface of the first wire, selecting a backup communication medium from one or more backup communication mediums according to one or more selection criteria, and redirecting the data to the backup communication medium to circumvent the fault. Other embodiments are disclosed.

Method and apparatus that provides fault tolerance in a communication network

Aspects of the subject disclosure may include, for example, a transmission device that includes a transmitter that generates a first electromagnetic wave to convey data. A coupler couples the first electromagnetic wave to a single wire transmission medium having an outer surface, to forming a second electromagnetic wave that is guided to propagate along the outer surface of the single wire transmission medium via at least one guided wave mode that includes an asymmetric or non-fundamental mode having a lower cutoff frequency. A carrier frequency of the second electromagnetic wave is selected to be within a limited range of the lower cutoff frequency, so that a majority of the electric field is concentrated within a distance from the outer surface that is less than half the largest cross sectional dimension of the single wire transmission medium, and/or to reduce propagation loss. Other embodiments are disclosed.

Guided-wave transmission device with non-fundamental mode propagation and methods for use therewith

Aspects of the subject disclosure may include, for example, receiving, from a second waveguide system, electromagnetic waves at a physical interface of a transmission medium that propagate without utilizing an electrical return path where the electromagnetic waves are guided by the transmission medium and where the electromagnetic waves have a non-optical frequency range, and authenticating the second waveguide system according to an authentication protocol based on authentication information contained in the electromagnetic waves. Other embodiments are disclosed.

Method and apparatus for authentication and identity management of communicating devices

Aspects of the subject disclosure may include, for example, accessing a profile including an expected fingerprint of expected parameters for received signals associated with a network path comprising a wired connection between network devices, comparing a fingerprint with the expected fingerprint where the fingerprint is generated from parameters measured from a signal, and authenticating a network device along the network path associated with the transmitting of the signal according to the comparing. Other embodiments are disclosed.

Signal fingerprinting for authentication of communicating devices

Aspects of the subject disclosure may include, for example, generating first traffic for transmitting along a network path to a recipient device and transmitting the first traffic along the network path to remove traffic patterns associated with a premises. Other embodiments are disclosed.

Method and apparatus for providing security using network traffic adjustments

Aspects of the subject disclosure may include, for example, a network device of a neighborhood network that determines that data is directed to a group of recipient devices positioned in a service area of the neighborhood network, determines a second network device according to a neighborhood routing scheme that limits delivery of the data to recipient devices within the service area, and transmits the data. Other embodiments are disclosed.

Method and apparatus for communications management in a neighborhood network

A method and apparatus for botnet analysis and visualization. Network traffic is filtered to compile a list of messages. The identified messages are tokenized, classified, and aggregated and changes in the frequency of tokenized messages are identified. A display of the tokenized messages is generated and displayed via a user interface. The user interface is configured to a allow a user to review data generated based on the filtered network traffic in order to detect potential botnet activity. User input may be used to adjust filtering and tokenization of the messages.
