Aspects of the subject disclosure may include, a system that facilitates receiving electromagnetic waves having polarized modes propagating along a transmission medium, detecting according to an analysis of the electromagnetic waves that the transmission medium is birefringent thereby causing a differential delay between the polarized modes, and adjusting a configuration of a receiver receiving the electromagnetic waves to mitigate the differential delay between the polarized modes. Other embodiments are disclosed.

Method and apparatus for managing propagation delays of electromagnetic waves

A framework in a cloud network that may allow for debugging at multiple vantage points at different layers (e.g., layer 2, layer 3, etc.). The methods may provide tracer or measurement services that filter, capture, or forward flows that may include packets, calls, or protocols to look for particular signatures.

Diagnostic traffic generation for automatic testing and troubleshooting

Aspects of the subject disclosure may include, for example, a method, includes coordinating relay transmission of a modulated signal via relay links of a distributed antenna system to reduce an accumulated forwarding delay in forwarding the modulated signal through the relay links. One of the relay links of the distributed antenna system reconverts the spectral segment of the modulated signal for transmission to a communication device to which the modulated signal is directed.

Distributed antenna system and methods for use therewith

Incorporation of a mesh base station in a wireless network is presented herein. The mesh base station can utilize common wireless resource allocations as a corresponding wireless base station while transmitting to wireless subscriber stations during the same time period. The mesh base station obtains a data packet from the wireless base station over a backhaul link during a scheduled time period and transmits the data packet to the designated wireless subscriber station during another scheduled time period. The wireless base station and the mesh base station can also receive data packets from wireless subscriber stations during a same time period. A wireless network can be configured with two mesh base stations at an approximate boundary of two adjacent sector coverage areas, where a coverage area is supported by a wireless base station and each mesh base station supports wireless subscriber stations within a coverage radius.

Incorporation of mesh base stations in a wireless system

A system and methodology that facilitates macrocell-to-femtocell handovers during an on-going communication session by augmenting a neighbor list with femtocell data is provided. Moreover, the femtocell data associated with a set of femtocells that the a user equipment (UE) is authorized to access is added to a neighbor list. When a handover is initiated, the femtocell data is utilized to facilitate scanning of a radio environment of the user equipment to detect a target cell site for the handover. In one aspect, location data and/or serving cell data associated with the set of femtocells is utilized to limit the number of femtocells that are added to the neighbor list.

Inbound handover for macrocell-to-femtocell call transfer

Aspects of the subject disclosure may include, for example, a device, process or software that determines an operation between a number of pairs of antennas of a set of antennas. A pair of antennas of the number of pairs of antennas is determined based on the operation. One antenna of the pair of antennas is eliminated from the set of antennas, which results in a reduced number of antennas remaining in the set of antennas. Each of the determining of the operation, the determining of the pair of antennas of the reduced number of antennas and the eliminating of the one antenna of the pair of antennas is repeated in response to the reduced number of antennas being greater than a predetermined number of antennas. Other embodiments are disclosed.

Method of selecting receive antennas for MIMO systems

A method and apparatus for providing radio communication with an electronic object in a local environment are disclosed. For example the method receives via a mobile endpoint device of a user at least one first digital certificate associated with the local environment from a trusted source, and a second digital certificate from the electronic device deployed in the local environment via a wireless connection. The method then authenticates the electronic device using the at least one first digital certificate and the second digital certificate.

A mobile participation platform enables a wireless network operator or third party to solicit response data related to a specific time and location specific event by signaling multiple mobile device users that meet predefined qualifications. The qualifications include presence at the specific location at the specific time, and may include other characteristics, such as prior consent to receive solicitations, and particular device type or data collection functionality. The platform locates mobile devices that may qualify for participation, and generates and transmits a solicitation. Mobile devices receiving the solicitation may activate a participation client to acknowledge the solicitation and to contribute by submitting the requested response data, which may include photos, text, sensor data, audio, video and the like. The qualifications are verified, the response data is validated, and anonymity and privacy are maintained by associating the mobile device and other pertinent non-identifying information with an encrypted identifier.

Location and time specific mobile participation platform

A method and computer readable medium for encoding data onto a channel broadcasting a program are disclosed. For example, the method selects a channel that is being used to broadcast a program, generates data having characteristics in accordance with an error burst signature and transmits the data on the channel that is being used to broadcast the program.
