20150351112 | METHOD AND APPARATUS FOR PROVIDING BEAM STEERING OF TERAHERTZ ELECTROMAGNETIC WAVES - A method and apparatus for establishing a terahertz link using a multi-element lens array that comprises a plurality of active beam steering device are disclosed. For example, the method receives detected terahertz signals from one or more detectors, where an active beam steering device is deployed with each of the one or more detectors, and determines, for each of the detected signals, if the detected signal is out of focus from a focus point. The method applies a corrective signal to each active beam steering device that corresponds to a detected terahertz signal that is out of focus from the focus point, wherein the corrective signal causes the detected signal to be redirected, and measures a signal-to-noise ratio of the detected signals. The method then establishes the terahertz link via at least one of the detected terahertz signals with a highest signal-to-noise ratio. | 2015-12-03 |
20150351113 | PORTABLE ELECTRONIC DEVICE - A portable electronic device of an embodiment has a communication section, a selection section, and a processing section. The communication section can communicate with an external device by a plurality of channels. The selection section selects a specification of class information which indicates a class of a command and included information indicating a channel number of the channel, from a plurality of the specifications of class information, based on prescribed information which is held in an own device and can be changed after a power source has been supplied. The processing section can execute command processings corresponding to a plurality of the specifications of class information, and when the communication section receives a command having the class information, executes the command processing corresponding to the specification of class information that the selection section has selected. | 2015-12-03 |
20150351114 | REAL-TIME PEER-TO-PEER COMMUNICATIONS IN AN ENVIRONMENT THAT INCLUDES A RESTRICTED CHANNEL - An apparatus and methods are provided for conducting wireless data communications, particularly real-time data communications, in a communication environment that includes a restricted channel (e.g., a channel subject to Dynamic Frequency Selection or DFS). Two or more mobile communication/computing devices (e.g., smart phones, tablet computers) participate in a peer-to-peer network and engage in data communications while one or more of them operate on the restricted channel (e.g., to maintain an infrastructure communication connection). Their channel sequences are configured to maximize the efficiency of the data communication while satisfying restrictions of the restricted channel or avoiding that channel, and only require them to monitor one beacon interval. One or more of the devices may strategically roam to the restricted channel or away from the restricted channel, depending on which action will provide greater communication throughput or efficiency. | 2015-12-03 |
20150351115 | DEVICES AND METHOD FOR RETRIEVING AND UTILIZING NEIGHBORING WLAN INFORMATION FOR LTE LAA OPERATION - A License Assisted Access (LAA) enhanced NodeB (eNB), user equipment (UE) and communication methods therebetween operating in a Long Term Evolution unlicensed band (LTE-U) are generally described. The eNB may transmit a request to the UE for information regarding a Wireless Local Area Network (WLAN) over which the UE may be able to communicate. The WLAN information may include an LTE-U channel and time window for reporting. The UE may obtain the WLAN information through communication with an access point (AP). Measurement information of the LTE-U channel may also be obtained by or on behalf of the UE. The UE may transmit the WLAN information to the eNB. The eNB may use the WLAN information or submit the WLAN information to a network entity to perform channel selection, UE grouping or localization, appointing delegate UEs to perform channel sensing or scheduling UEs in a same group or proximity. | 2015-12-03 |
