Abstract: A method, an apparatus, and a computer program product for communication are provided. The apparatus obtains a message for communication using visible light communication (VLC) through a light emitting diode (LED) luminary device and formats the message using a synchronization signal followed by one or more data signals. The synchronization signal and/or the one or more data signals are modulated using a Frequency Shift Keying (FSK) modulation scheme. The apparatus further receives a dimming level value associated with a brightness of light to be emitted from the LED luminary device, generates a waveform with frequencies based on the formatted message and a duty cycle for the LED luminary device based on the dimming level value, and sends the generated waveform to the LED luminary device for communication using VLC.

Abstract: A hybrid communications system implements different communication technologies to communicate data and information for particular communications directions in different portions of the system. Power line communications (PLC) signaling is used to deliver data and information from a gateway device to a light access point. Visible light communications (VLC) signaling is used to communicate data and information from the light access point to a user equipment (UE) device. Wireless radio signaling, wireless infrared (IR) signaling, or a combination of wireless IR signaling and PLC signaling is used to communicate data/information from the UE device to the gateway device. To efficiently control the VLC communications channel between the light access point and UE device, the UE device measures the VLC channel, e.g., calculating SNRs on a per VLC tone basis, and communicating VLC channel quality feedback information to the gateway device, which is forwarded to the light access point.

Abstract: Various exemplary methods and apparatus are directed to using Visible Light Communication (VLC) in a downlink, e.g., a supplemental downlink, in combination with a wireless radio downlink/ uplink pair. A gateway is coupled, via a wireline link, to a VLC access point. In some embodiments, the gateway includes a wireless radio base station. A user equipment device detects a visible light signal from the VLC access point, and transmits a radio signal to a communications device, e.g., a gateway including a base station or a macro base station, indicating that the UE device is in a VLC coverage area. The gateway configures the VLC access point to serve as a supplemental wireless cell which supports downlink communications. The gateway sends traffic signals to the VLC access point, via the wireline, which are converted by the VLC access point into VLC signals which are transmitted. The UE device receives VLC downlink traffic signals and transmits a corresponding acknowledgment signal via an uplink radio channel.

Abstract: Disclosed are methods, systems, devices, apparatus, computer-/processor-readable media, and other implementations, including a method, at a processor-based mobile device, that includes determining a first set of candidate positions of the mobile device corresponding to a first time instance based, at least in part, on position data including a first set of identifiers decoded from signals including respective first one or more light-based communications received by the mobile device from a first one or more light devices, with the mobile device being located at a first location at the first time instance. The method further includes selecting at least one candidate position from the first set of candidate positions, in response to a determination that the first set of candidate positions includes more than one candidate position, in order to resolve positional ambiguity, based, at least partly, on further position data from further signals from one or more devices.
