摘要
A Wireless LAN (WLAN) Li-Fi transceiver includes a Wi-Fi device and an Analog Front-End (AFE). The Wi-Fi device is configured to produce a spatial stream carrying data, and to produce from the spatial stream In-phase and Quadrature (I/Q) signals for transmission over a radio channel having a predefined Radio Frequency (RF) band. The Analog Front-End (AFE) is configured to modify the I/Q signals, or modify operation of the Wi-Fi device, for producing a real Li-Fi signal in a predefined optical band, and to transmit the data carried by the spatial stream to a remote Li-Fi receiver by driving an optical emitter with the real Li-Fi signal.
