Patent application EP20182448A (EP), filed 2020-06-26
Publication number: EP3757614A1
Title: MOBILE TERMINAL
Abstract: A mobile terminal is provided. The mobile terminal includes a light emitter, a light receiver, a light fidelity (LiFi) controller coupled with the light emitter and the light receiver, and a time-of-flight (TOF) controller coupled with the light emitter and the light receiver. The LiFi controller is configured to control the light emitter to emit a signal and control the light receiver to receive another signal. The TOF controller is configured to control the light emitter to emit a measurement light and determine a measured distance by performing distance measurement according to a reflected light of the measurement light received by the light receiver.
