Abstract: A system for enhanced internet of things digital certificate security is provided. The system includes a computer device. The computer device is programmed to store, in a database, a plurality of statuses associated with a plurality of digital certificates. The computer device is also programmed to receive, from a first computer device, a status update for the first digital certificate. The computer device is further programmed to update the first status based on the status update. Subsequently to updating the first status, the computer device is programmed to receive a request for a connection from the first device. Subsequently to updating the first status, the computer device is also programmed to deny the request for a connection based on the first status.

Abstract: A radio access network (RAN) node is provided for a small cell of a wireless access network having a coaxial line. The RAN node includes an input operably coupled with the coaxial line and an output configured to wirelessly communicate with at least one user equipment device within an operable vicinity of the wireless access network. The RAN node further includes a transmission path configured to (i) connect the input to the output, and (ii) communicate a first radio frequency (RF) signal from the input to the output, and a reception path separate from the transmission path, and configured to (i) connect the output to the input, and (ii) communicate a second radio frequency (RF) signal from the output to the input. The RAN node is configured to dynamically switch between the transmission path and the reception path in response to a tone received from the wireless access network.

Abstract: An authenticating system and process for authenticating user devices to a access a service where access to certain portions of the service may be limited according to a access point or other device used by a user device to facilitate interfacing a user with the service. The authentication may be achieved without directly assessing a trustworthiness of the user devices, and optionally, without requiring a user thereof to complete a sign-on operation.

Abstract: In an embodiment, a network-based media processing system includes a media control plane implementing a first network protocol. The media control plane includes a media origin server. The system further includes a network control plane implementing a second network protocol. The network control plane includes a network platform orchestrator, a network orchestration client, a network resource element, and a plurality of media processing elements. A system further includes a media data plane implementing a third network protocol. The media data plane includes a plurality of media resources. The system further includes a media interchange format configured to provide a unified data format for delivering media according to a format requested from a client device. The first network protocol is different from the second network protocol.

Abstract: Methods, systems, and devices for Content-Centric Networking (CCN) are described. In some cases, a node may receive a CCN packet from an upstream node and communicate the CCN packet to one or more downstream nodes (e.g., that previously requested the CCN packet). In a first case, the node may establish a persistent internet protocol (IP) tunnel with the downstream node and communicate the CCN packet to the downstream node by the persistent IP tunnel. Here, a cable modem between the node and the downstream node may not decode the CCN packet. In a second case, the node may append an identifier to the CCN packet prior to communicating the CCN packet to the one or more downstream nodes. Here, the identifier may indicate to the downstream nodes which CCN packets are relevant to the downstream node.

Abstract: An assessment tool for assessing signaling ingress and small cell placement within a communication network is contemplated. The assessment tool may include capability sufficient for assessing signaling ingress associated with radio frequency (RF) signaling attenuating, influencing or otherwise interfering with other signaling being transmitted over a communication network.

Abstract: A method of facilitating zero sign-on access to media services depending on trust credentials. The trust credentials may be cookies, certificates, and other data sets operable to be stored on a device used to access the media services such that information included therein may be used to control the zero sign-on capabilities of the user device.

Abstract: Methods, systems, and devices for a decision directed multi-modulus searching algorithm are described. A receiver may receive a signal including a set of data symbols. The receiver may iteratively determine a set of centroids for demodulating the set of data symbols (e.g., as part of a training procedure). The centroids may be used to demodulate the set of data symbols according to a modulation constellation associated with the set of data symbols. The training procedure may include, for each data symbol of a subset of data symbols, assigning a centroid of the set of centroids to each data symbol and updating the set of centroids based on assigning the centroid to each data symbol. The receiver may demodulate the set of data symbols based on the updated set of centroids.

Abstract: A method of modulating a series of input digital symbols of a first modulation scheme is provided. The method is implemented by a transmitter and includes receiving a sequential series of samples of the digital symbols in a first domain of the first modulation scheme. The first domain is one of the time domain and the frequency domain. The method further includes determining a dual of the first modulation scheme. The dual has a second modulation scheme in a second domain that is different from the first domain the second domain is the other of the time domain and the frequency domain. The method further includes applying a 90 degree rotational operation to the second modulation scheme to generate a rotational modulation format, modulating the series of digital symbols with the generated rotational modulation format, and outputting the modulated series of digital symbols to a receiver.
