    摘要: Multiplexed unequal error protection for wireless networks is disclosed. A device may determine reliability associated with a first subcarrier of a channel including the first subcarrier and at least one second subcarrier. The reliability of the first subcarrier may be determined based on the position of the first subcarrier relative to each at least one second subcarrier. High priority data may be assigned to the first subcarrier for transmission if the first subcarrier is determined to have a higher reliability than the at least one second subcarrier. For example, the channel may be an orthogonal frequency division multiplexed (OFDM) channel and higher reliability may be associated with a first subcarrier that is in a middle position of the plurality of subcarriers within the OFDM channel. In another example, higher reliability may be associated with a first OFDM subcarrier that is adjacent to an unused OFDM channel bandwidth.

    摘要: Application data traffic transmitted and received by wireless devices in a network may be mapped to channels based on traffic type and channel metrics. The traffic type may be classified by modality such as by voice, video, application sharing, instant messaging, emergency call, or any other application modality. The channels may be associated with characteristics that include, for example, a frequency band or channel metrics. The traffic types may be prioritized relative to one another and each may be associated with a hierarchical frequency band prioritization or a channel prioritization based on other channel metrics. A list of traffic types or modalities may be mapped to a list of available channels in a network by mapping channel characteristics to modalities based on modality traffic type prioritization, frequency band prioritization or channel metric prioritization. The mapping may then be utilized to control channel assignment for devices operating in the network.

    摘要: The patterns of usage, participation, and/or item sharing by the participants in a conference call are correlated, recognized, and used to select a data centers. This selection can be done both before and/or during a call. When significant patterns are recognized (e.g., heavy video sharing by one participant at every Friday afternoon meeting) there may be a better (e.g., faster, better quality, more efficient, less use of network resources) data center to host the call than one that is selected based on the geography of the participants alone. Likewise, during a call, other patterns of behavior can be correlated and recognized dynamically such that when these patterns occur, the call is hosted by a different (i.e., better) data center.

    摘要: A method and apparatus is disclosed by which a device in a wireless network may determine and reduce interference when using channels in restricted frequency bands and when other networks may be transmitting in the same restricted frequency. The wireless network may be a Wi-Fi system utilizing channels/frequencies in the television white space. Receivers, such as a client device and access point (AP), may determine information on one or more interfering signals and utilize the information to reduce or cancel the interference caused by the interfering signals generated by a second network. The information may be parameters or information on the structure of the interfering signal, and may be determined by retrieving stored cache information, receiving information on a beacon signal or sampling an interfering signal. The interference cancellation may be performed by joint demodulation or parallel interference cancellation.

    摘要: Systems, methods, and software technology for partitioning media streams is disclosed herein. In an implementation, a network node receives a media stream for a multimedia session from an upstream node in a communication channel supporting the multimedia session, partitions the media stream into a plurality of sub-streams to vary a code rate of each sub-stream of the plurality of sub-streams relative to each other, and transmits the plurality of sub-streams to a plurality of downstream nodes over a plurality of channels supporting the multimedia session.

    摘要: A method for generating a spreading sequence is disclosed. The method includes receiving a plurality of signals from a remote device. The plurality of signals is sampled to generate a plurality of data sets corresponding to the plurality of signals, respectively. Each data set indicates a power value of the corresponding signal. From the plurality of data sets, one or more data sets indicating a power value greater than a predetermined value is selected. A spreading sequence is generated based on the one or more selected data sets.

    摘要: Systems, methods, and software technology for partitioning media streams is disclosed herein. In an implementation, an application partitions an encoded media stream into multiple sub-streams having different code rates relative to each other. The sub-streams may then be transmitted to different wireless access points. A change in a monitored performance of at least one of the wireless access points may drive a modification to the partitioning of the media stream such that the code rates change relative to each other.

    摘要: Online content is served to participant devices using two or more systems. The content served by each system is not the same. Rather, the content streams coming from each system is a partial or lower-quality version of the original high-quality version of the content stream. A single one of the partial data streams can be used by the participant device to output a lower-quality version of the original content stream to the user. Alternately, the received partial content streams can be combined to output, to the user, a high-quality version of the original content stream.
