The transmitter may include a memory for storing an identifier of the transmitter, a processor for generating a data signal including an identifier of the transmitter, a modulator for receiving the data signal and generating an electrical signal, the modular generating the electrical signal by modulating the data signal. The transmitter may also include a light source for receiving the electrical signal, converting the electrical signal into an optical signal, and continuously broadcasting the optical signal as an optical data transmission stream. The optical data transmission stream may be used to verify that a receiving mobile device is near the transmitter. The transmitter may also include an optical surface for dispersing the optical data transmission stream as the optical data transmission stream is emitted from the transmitter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Modulating a light source in a light based positioning system with applied DC bias","description":"In one aspect, the present disclosure relates to a self-identifying optical transmitter for broadcasting a one-way authentication code using light-based communication.
