摘要： A communication system includes a cloud server that further includes a processor. The processor obtains sensor data associated with a defined indoor area and a plurality of optical nodes in defined indoor area. The processor further obtains location coordinates of the plurality of optical nodes in the defined indoor area. The processor then causes the master communication device to form a laser beam-based wireless communication network in the defined indoor area based on the obtained sensor data and the location coordinates of the plurality of optical nodes.

摘要： Useful data is transmitted to a terminal existing in a transportation vehicle. A communication apparatus installed in the transportation vehicle and configured to transmit the data to the terminal existing in the transportation vehicle includes a data selection unit and an illumination unit. The data selection unit acquires location information indicating a location of the transportation vehicle in which the terminal exists and which is traveling. Based on the acquired location information, the data selection unit selects approaching-location data related to a location ahead of a current location of the transportation vehicle in a traveling direction from a plurality of pieces of data related to the location. The illumination unit transmits, as a modulated light signal, a signal comprising the approaching-location data.

摘要： This invention relates to a power supply system for an optical wireless communication system where a modem (212) is connected to a plurality of transceivers (11). The underlying idea being that the transceivers (11) are powering the modem (212), rather than the modem (212) powering the transceivers (11). To achieve this, a power combiner is provided that can receive power from the transceivers (11). The transceivers (11) power down when no endpoint is detected and use a subset of emitters, in which case the modem (212) can also be switched to a lower power mode.

摘要： A user device may use a light communications system to detect, from a light source in a physical space, light in a pattern that represents encoded information. The light communications system may include a sensor and an emitter. The user device may decode the encoded information based on the pattern to cause an update associated with a virtual meeting. In some implementations, the update may include the user device joining the virtual meeting using a meeting identifier. In some implementations, the update may include adjusting a microphone or a speaker in the physical space. In some implementations, the update may include a pairing between the user device and a second device that enables bidirectional communication between the user device and the second device.

摘要： A communication system that includes a cloud server that obtains first sensor data associated with a defined indoor area and second sensor data associated with each of a plurality of optical nodes in defined indoor area. The plurality of optical nodes includes a master communication device, a plurality of optical routing devices, and one or more service communication devices. The cloud server further obtains location coordinates of each of the plurality of optical nodes. The cloud server then causes the master communication device to form a laser beam-based wireless communication network in the defined indoor area. The laser beam-based wireless communication network is one of a Laser Beam Mesh Network (LBMN) or a Laser Beam Cascaded Network (LBCN).

摘要： An optical wireless communication (OWC) system comprises an OWC network and a further OWC network. The OWC network comprises a primary OWC apparatus configured for connection to an electronic network and one or more secondary OWC apparatuses, each secondary OWC apparatus configured for incorporation into, or connection to, or comprising, a corresponding user device. The further OWC network comprises a further primary OWC apparatus configured for connection to a further electronic network and one or more further secondary OWC apparatuses, each further secondary OWC apparatus configured for incorporation into, or connection to, a corresponding user device. The primary OWC apparatus and each of the one or more secondary OWC apparatuses are configured for communication of one or more OWC signals therebetween on one or more optical wavelengths, each OWC signal comprising corresponding data and a corresponding identifier code. The further primary OWC apparatus and each of the one or more further secondary OWC apparatuses are configured for communication of one or more further OWC signals therebetween on one or more further optical wavelengths, each further OWC signal comprising corresponding further data and a corresponding further identifier code. At least one of the one or more further optical wavelengths is different to at least one of the one or more optical wavelengths and wherein at least one of the one or more further identifier codes is different to at least one of the one or more identifier codes.

摘要： A pluggable connector is provided for use in an optical wireless communications, OWC, system. A main housing has an electrical connector for pluggable connection to a socket, with an optical transmitter and receive circuitry in the main housing. A carrier part has an adjustable orientation relative to the main housing and includes a (passive) optical output device for delivering an optical communications signal beam and an (active) optical receiver for receiving an optical communications signal beam. A flexible optical connector is provided between the optical transmitter and the optical output device and a flexible electrical connector is provided between the optical receiver and the receive circuitry. This provides a hybrid connection scheme between a movable optical carrier part and a static electrical part.

摘要： A system for optical communication includes at least one light source for transmitting optical signals, at least one optical receiving unit for receiving the optical signals of the at least one light source, at least one mask unit, which is arranged between the optical receiving unit and the at least one light source, and which is designed to be switchable back-and-forth at least in areas between an at least partially optically non-forwarding and at least partially optically forwarding state. An image of at least one light-emitting area of the at least one light source can be imaged onto the at least one mask unit and in the at least partially forwarding state of the at least one mask unit can be conducted to the receiving unit. A method for optical communication is also provided.

摘要： The disclosure provides for a method for reacquiring a communication link between a first communication device and a second communication device. The method includes using one or more processors of the first communication device to receive historical data related to the first communication device and an environment surrounding the first communication device. The one or more processors are then used to determine one or more trends in the historical data related to fading of the communication link. Based on the one or more trends, the one or more processors are used to determine a starting time and an initial search direction for a search for the communication link. The one or more processors then execute the search at the starting time from the initial search direction.
