article description
A system and method are proposed that may transfer information between devices using both LiFi and the WiFi technologies. The hybrid system may use LiFi for downlink traffic and WiFi for uplink traffic. The system may include a LiFi receiver/transmitter and also a WiFi receiver/transmitter in the devices. When a device tries to communicate with a network, the data is uploaded from the device to the router connected to the network through WiFi. The device receives response from the network via the router through LiFi. The disclosed hybrid system incorporates the high download speed of LiFi (up to 4 Gbps), while maintaining the reliability of WiFi (upload speed up to 0.443 Gbps).
