Abstract:
Camera Communication (CamCom) systems may be used to communicate data using visible light as the medium, and in which the camera is the receiver. In various embodiments, high speed communications may be achieved with a high frame rate digital camera, but without using region of interest (ROI) subsampling to reduce the number of pixels being considered. In particular, the camera may be a dynamic vision sensor (DVS) camera in which each pixel sensor detects a change in light level (such as a pulse) that exceeds a threshold value, and generates a 'pixel event' in response that indicates various information about the detection.
Abstract:
Optical wireless communication techniques are described and claimed. In one embodiment, the disclosure relates to method and apparatus to provide optical signaling with visible light having variable pulse position modulation (VPPM). The optical signal includes a Start Frame Delimiter (SFD) which indicates beginning of an asynchronous optical signaling. The VPPM signaling includes a lower frequency time varying amplitude component that when subsampled by a low frame rate camera results in alias induced flicker or blinking. Such signals are quickly recognizable as signals with modulated data. In another embodiment, the disclosure provides a system, device and method for decoding a Start Frame Delimiter (SFD) to indicate arrival of incoming VPPM optical data.
Abstract:
Methods and apparatus to facilitate a synchronous transmission opportunity in a wireless local area network are disclosed. An example apparatus includes a transmission opportunity characteristic determiner to divide a transmission opportunity into transmission intervals, each of the transmission intervals being reserved for at least one of an uplink transmission or a downlink transmission; a preamble generator to generate a preamble including information related to durations of the transmission intervals and a total number of transmission intervals; and an interface to transmit the preamble to a station to initiate the transmission opportunity.
Abstract:
This disclosure describes systems, methods, and apparatus related to enhanced acknowledgements for wireless networks for time sensitive applications. A physical layer (PHY) protocol data unit (PPDU) received from a station device may be identified. The PPDU may include an aggregate media access control protocol data unit (A-MPDU). The A-MPDU may include a plurality of media access control protocol data units (MPDUs). A status for each of the plurality of MPDUs may be determined. An acknowledgement (ACK) report based on the status for each of the plurality of MPDUs may be determined. A response PPDU that includes a lightweight (LW) ACK may be sent to the station device.
Abstract:
Various systems and methods for identifying and performing authentication of visible light communications using optical camera communication techniques are described. In an example, an electronic processing system to authenticate a particular light emitting source includes electronic operations for: detecting, from image data, modulated light data emitted from a light emitting object, where the image data depicts the light emitting object, and where the image data is captured with an image sensor (e.g., of a camera); identifying, from the image data, the light emitting object as a source of the modulated light data; receiving an indication to select the light emitting object as an authenticated source of the modulated light data; and performing a command to process the modulated light data from the authenticated source, with the command performed in response to the indication to select the light emitting object as the authenticated source of the modulated light data.
Abstract:
A station (STA), when operating as a responding STA (RSTA) for time-synchronization of a plurality of initiating STAs (ISTAs) in a time-synchronized network (TSN), may determine, during a negotiation phase, whether each of the ISTAs that intend to participate in one or more measurement phases are requesting to be polled or are requesting not to be polled. For the ISTAs that are requesting to be polled, the RSTA may perform a polling phase prior to performing each of the one or more measurement phases. For the ISTAs that are requesting not to be polled, the RSTA may refrain from performing a polling phase prior to performing each of the one or more measurement phases. The RSTA can directly trigger the measurement phase for ISTAs that are requesting not to be polled. By grouping ISTAs into polling and non-polling groups, efficiency improvements are achieved.
