The device includes: a transmitting device, configured to transmit a first signal to an opposite terminal; and a receiving device, configured to receive a second signal transmitted by the opposite terminal, where a frequency of the first signal is different from a frequency of the second signal, and the frequency of the first signal and/or the frequency of the second signal are/is in a frequency band of visible light. The present invention resolves a problem in a related technology that poor reliability of uplink and downlink signal transmission is caused when signals of a same frequency are used for uplink and downlink transmission, and provides a beneficial effect of improving reliability of uplink and downlink signal transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal transmission method and device","description":"The present invention provides a signal transmission method and device.
