Abstract

The present disclosure provides systems and methods for synchronizing the time signals of master and remote lEDs using a radio link. According to one embodiment a master lED may transmit an adjusted time signal to a remote lED via a radio signal. The master lED may determine a propagation delay between the master lED and a remote lED. The master lED may then adjust a master time signal by the propagation delay and transmit the adjusted time signal to the remote lED. Alternatively a remote lED may request and receive a master time signal from a master lED via a radio signal. The remote lED may then determine the propagation delay and adjust the received master time signal accordingly. According to various embodiments the time signal of a master and remote lED may be synchronized to within at least one millisecond.
