An optical transmission/reception unit includes a carrier rotatable around an axis of rotation, an optical receiver arranged at the carrier on the axis of rotation so as to receive an optical reception signal from a first direction, an optical transmitter arranged at the carrier adjacent to the optical receiver so as to emit an optical transmission signal in a second direction, and a transmission/reception optic arranged at the carrier on the axis of rotation above the optical receiver, wherein the transmission/reception optic includes a reception optic and a transmission optic arranged in the reception optic, wherein the reception optic is configured to guide the optical reception signal striking the transmission/reception optic towards the optical receiver on the axis of rotation, and wherein the transmission optic is configured to displace onto the axis of rotation the optical transmission signal emitted by the optical transmitter.

An LED light fixture includes one or more optical transceivers that have a light support having a plurality of light emitting diodes and one or more photodetectors attached thereto, and a processor in communication with the light emitting diodes and the one or more photodetectors. The processor is constructed and arranged to generate a communication or data transfer signal.

Methods, systems, and apparatuses for light-based communication are described. VLC may be used to communicate video content, an electronic program guide (EPG), location information, an advertisement, and/or any other data, content, and/or content item to a user device. VLC may be used to communicate data/information associated with a wireless network, provision a service, navigate an area, track content and/or content item consumption, and more. Light (e.g., VLC, etc.) may be used to communicate any information/data.

A system and method wherein electromagnetic radiation is used for free-space communication and wireless power transfer. The electromagnetic radiation used is preferably optical radiation. The optical free-space communication and wireless power transfer system includes an optical receiver device comprising an optical filter, a photodetector, and a photovoltaic cell, wherein a band of the incoming optical radiation is extracted by the optical filter and directed to the photodetector for communication data signal detection. The remaining optical radiation is converted by the photovoltaic cell into electrical power so that the harvested energy can be stored, used as the power source of the photodetector, or used as the power source of external devices.

A method by a coordination node is provided for controlling communications between Li-Fi APs and UEs. The method includes receiving peer connectivity reports from Li-Fi APs which identify Li-Fi APs having at least partially overlapping coverage areas, and developing a handover pathway data structure, based on the peer connectivity reports, that identifies Li-Fi APs that can receive communication handover from other identified Li-Fi APs. The method further includes determining an identifier of a first Li-Fi AP providing Li-Fi communication service for a UE, and accessing the handover pathway data structure using the identifier of the first Li-Fi AP to determine an identifier of a second Li-Fi AP to which handover from the first Li-Fi AP can be performed. The method then initiates handover of the Li-Fi communication service for the UE from the first Li-Fi AP to the second Li-Fi AP.

Embodiments are directed to systems and methods for providing light communication (LC) for an aircraft. An LC transmitter is mounted on an aircraft fuselage and is configured to broadcast light signals within a defined region outside the aircraft. An LC receiver mounted on the aircraft fuselage is configured to receive light signals broadcast by a remote LC device. A controller is configured to manage LC signals in the aircraft, and an interface is provided between the controller and an aircraft data network. The light signals may be in a visible light spectrum, an invisible light spectrum, or both. The remote LC device may be, for example, a ground station, an aircraft, a ground vehicle, a ship, a building, or a portable transmitter.

There is provided a moving body including: an optical wireless communication unit configured to execute an optical wireless communication with another moving body; an object detection unit configured to detect an object around an own moving body; an object information transmission unit configured to transmit, to the other moving body, first object information including location information of the object, by the optical wireless communication or a radio wave communication; an object information receiving unit configured to receive, from the other moving body, second object information including location information of an object around the other moving body, by the optical wireless communication or the radio wave communication; and a movement control unit configured to control, based on the first object information and the second object information, a movement of the own moving body such that an object is not located on an optical axis of the optical wireless communication.

Methods, systems, and computer readable media can be operable to facilitate recognizing and providing notification of events, states, and/or conditions associated with the CPE device and/or associated networks or devices. An application running on a mobile device (e.g., smart phone) can be used to observe and diagnose electronic equipment (e.g., CPE device). Equipment can have indicators (audio, visual, etc.) that a human would have difficulty interpreting correctly. A mobile device application can be programmed to observe audio and/or visual indicators, report status and possibly recommend course(s) of corrective action to the user. Since the information observed by the mobile device is unidirectional (from the equipment to the mobile device) there is no increased security risk.

An LED light and communication system is in communication with a broadband over power line communications system. The LED light and communication system includes at least one optical transceiver light fixture. The optical transceiver light fixture includes a plurality of light emitting diodes, at least one photodetector, and a processor. A facility control unit is in communication with the light emitting diode light fixtures and a control server. The facility control unit is constructed and arranged to control the operation of the optical transceiver light fixtures.
