In this paper, we propose an efficient reconfiguration technique providing control over multiple beams independently.

This method is easy to implement, effective and efficient since it only requires phase reconfiguration.

Further, we report a considerable increase in the system throughput given the outdoor environment. The work of Gabriele Gradoni was supported by the Royal Society under Grant INF\R2\192066.
