  • Publication number: 20140293870
    Abstract: A system and method are provided for triggering re-beamforming in a 60 GHz communication link based on information collected from platform positional sensors associated with one or the other or both of the transmitters/receivers that constitute ends of the communication link. The disclosed systems and methods monitor various positional sensors that may be used to sense translational and rotational movement of at least one of the platforms on which at least one of the transmitters/receivers is mounted. Information provided by the positional sensors is processed to determine whether or not to trigger re-beamforming for link recovery in 60 GHz communication link. Information provided by the sensors may be used in combination with other link operating metrics, such as PER and RSSI, to make an intelligent determination whether to trigger re-beamforming.

  • Publication number: 20140219291
    Abstract: A system and method are provided that allow WiGig protocol adaptation layers (PALs) to operate differently from the proposed WiGig standard on top of an Internet protocol (IP) layer in order to enhance routing options for communication of the data traffic between a transmitting (source) device and a receiving (sink) device. A layering architecture is provided that allows WiGig PALs, such as WDE, to operate on top of an IP layer. A signaling mechanism is also provided that allows a negotiation, or at least an indication, of the underlying layering structure for specific data communications. Recognizing that the next generation wireless display requires technology such as WiGig WDE to support the driving demand for a cable replacement user experience and richer wireless display use cases, this PAL over IP architecture optimizes alignment of the WiGig data communication technology with other data communication technologies.
