Abstract
A method for communicating from a transceiver including a sub-transceiver array includes setting the sub-transceiver array to emit an optical signal at an initial pointing angle, and modifying at least one of the sub-transceivers to emit a first optical sub-signal at a first pointing angle having a first offset from the initial pointing angle. The method further includes, during a first transmit period, transmitting to a receiving transceiver from the sub-transceiver array a first optical signal including the first optical sub-signal, at a first data rate. The method also includes further modifying the sub-transceiver to emit a second optical sub-signal at a second pointing angle having a second offset from the initial pointing angle, the second offset being smaller than the first offset, and, in a second transmit period, transmitting to the receiving transceiver from the sub-transceiver array a second optical signal including the second optical sub-signal.
