A first wireless communication device includes a plurality of antenna elements, a transceiver coupled to the plurality of antenna elements, and a focusing element positioned in a transmitting path of at least one of the plurality of antenna elements. The transceiver is configured to transmit, to a second wireless communication device, a multiple-input multiple-output (MIMO) signal. The transceiver configured to transmit the MIMO signal is configured to: transmit, to the second wireless communication device via a first antenna element of the plurality of antenna elements, a first communication signal; and transmit, to the second wireless communication device via a second antenna element of the plurality of antenna elements, a second communication signal. The focusing element is configured to: direct the first communication signal in a first direction; and direct the second communication signal in a second direction different from the first direction.
