The receiver receives from a first laser device of the QD Vcel cannon, a first light pulse of the plurality of multi- frequency light pulses. The first light pulse includes a first frequency for testing a visibility of the first light pulse at the receiver. The receiver determines if the first light pulse is visible at the receiver.
