A wireless communication device (alternatively, device, WDEV, etc.) includes a processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV generates an orthogonal frequency division multiple access (OFDMA) frame that includes OFDMA symbol(s) that include a set of pilots based on an OFDMA sub-carrier plan. The WDEV transmits the OFDMA frame to other WDEV(s) for use by the other WDEV(s) to perform estimation of communication pathway(s) between the WDEV and the other WDEV(s) using the set of pilots. The OFDMA sub-carrier plan includes multiple OFDMA sub-carrier sub-plans of different sized RUs including pilots.

The disclosure provides methods and systems for processing audio signals. The method may comprise receiving, via an application displayed at a client computing device, an audio signal and a user control input for controlling an audio processing effect of the audio signal. Then, the method may comprise sending, via a wide area network connection, the audio signal and the user control input to an audio server and then relaying the audio signal through the audio server to an input of an audio processing device. The method may also comprise controlling a setting on the audio processing device through a hardware controller based on the user control input, and returning a processed version of the audio signal from the audio processing device to the client computing device.

Upon receipt of a packet addressed to a virtual IP address assigned to each first device from a second device outside a base network, a processor identifies a base relay apparatus that accommodates the first device, to which the virtual IP address is assigned, on the basis of the virtual address and a protocol type of the received packet, and also identifies a reception port number of the identified base relay apparatus, which corresponds to a combination of the virtual IP address and the protocol type of the received packet, from among reception port numbers each assigned to a combination of the first device accommodated to identify a transfer destination, and a protocol type. Then, the processor relays the received packet to the identified reception port number of the identified base relay apparatus.

An OFDM transmitter spreads original data symbols with a complex-valued spreading matrix derived from a discrete Fourier transform. Spread data symbols are mapped to OFDM subcarriers. Spreading and mapping are configured to produce a transmitted spread-OFDM signal with a low peak-to-average power ratio (PAPR) and orthogonal code spaces. In MIMO systems, the complex-valued spreading matrix can comprise a MIMO precoding matrix, and the code spaces can comprise MIMO subspaces. In Cooperative-MIMO, a combination of low code-space cross correlation and low PAPR can be achieved.

Elastic message tracking apparatus and methods are provided that opportunistically improve on the latency of a message processing system and increase the accuracy of a consolidated message stream generated from message streams received from multiple message sources. The elastic message tracking apparatus and methods reduce that latency in situations where the actual latency of all the message streams is lower than a predetermined latency value.

Distributed conferencing systems and methods provide local meeting contents to remote participants. In accordance with various example embodiments, a plurality of authorized source units generate media content responsive to and representative of respective content for a meeting. In response to the generated media content, one or more data streams are developed at each authorized source, each stream being a separately-decodable real-time representation of at least a portion of the media content generated at the respective authorized source. The separate data streams are transmitted by each authorized source to a common multicast IP group address for retrieval/access by remote participants.

In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for traffic aggregation on multiple WAN backhauls and multiple distinct LAN networks; for traffic load balancing on multiple WAN backhauls and multiple distinct LAN networks; and for performing self-healing operations utilizing multiple WAN backhauls serving multiple distinct LAN networks. For example, in one embodiment, a first Local Area Network (LAN) access device is to establish a first LAN; a second LAN access device is to establish a second LAN; a first Wide Area Network (WAN) backhaul connection is to provide the first LAN access device with WAN connectivity; a second WAN backhaul connection is to provide the second LAN access device with WAN connectivity; and a traffic aggregation unit is to form a logically bonded WAN interface over the first WAN backhaul and the second WAN backhaul. In some embodiments an optional traffic de-aggregation unit may be used.

A sensor-integrated communication module that is insertedly coupled to one side of a home appliance may include a communication unit for transmitting/receiving a signal to/from an external device by using wireless communication, a sensor unit for collecting ambient information, and a control unit for controlling an operation of the home appliance in consideration of the ambient information.

Examples include detection of a status of an uplink in an SD-WAN. Some examples use a predicted probe profile determined based on predicted RTT values generated using a machine learning algorithm for estimating whether the uplink is failed. In response to estimating that the uplink is failed, some examples compute a confidence level value and determine whether the estimated failure of the uplink is acceptable based on the confidence level value to detect a status of the uplink.

A system is described for maintaining synchrony of operations among a plurality of devices that have independent clocking arrangements. The system includes a task distribution device that distributes tasks to a synchrony group comprising a plurality of devices that are to perform the tasks distributed by the task distribution device in synchrony. The task distribution device distributes each task to the members of the synchrony group over a network. Each task is associated with a time stamp that indicates a time, relative to a clock maintained by the task distribution device, at which the members of the synchrony group are to execute the task. Each member of the synchrony group periodically obtains from the task distribution device an indication of the current time indicated by its clock, determines a time differential between the task distribution device's clock and its respective clock and determines therefrom a time at which, according to its respective clock, the time stamp indicates that it is to execute the task.
