Apparatus, system and method of steering directional antenna

Some demonstrative embodiments include apparatuses, systems and/or methods of steering a directional antenna. For example, a transmitter to transmit a beacon via a steerable directional antenna, the beacon including a multi-directional sounding preamble including a plurality of sounding signals transmitted via a respective plurality of directional sectors of the antenna, each sounding signal including a plurality of repetitions of a detection sequence; a receiver to receive one or more responses from one or more respective wireless communication devices via one or more directional sectors of the plurality of directional sectors; and a controller to select the one or more directional sectors to communicate with the one or more wireless communication devices. 些说明性实施例包括对定向天线进行导向的装置、系统和/或方法。例如，发射器，用于经由可导向的定向天线发送信标，该信标包括多方向探测前导码，该多方向探测前导码包括经由天线的相应多个定向扇区发送的多个探测信号，每个探测信号包括检测序列的多个重复；接收器，用于经由多个定向扇区中的个或多个定向扇区，从个或多个相应的无线通信设备接收个或多个响应；以及控制器，用于选择个或多个定向扇区以与个或多个无线通信设备通信。
