Abstract

Systems and methods for communicating using both radio frequency (RF) communication and light communication (LC) are disclosed. An example device comprises radio frequency communication circuitry, a light communication transmitter; a light communication receiver; a processor for controlling the device according to executable code; and memory for storing data and executable code, wherein the executable code comprises instructions for causing the processor to establish RF communication with an RF access point using the RF communication circuitry; and to establish LC communication with an LC access point using the LC transmitter, the LC receiver, or both.
