Abstract: An access point (14) operates in an 802.11 wireless communication network (10) communicating with a client station (12), and includes a smart antenna (16) for generating directional antenna beams (20) and an omni-directional antenna beam (22). An antenna steering algorithm (18) scans the directional antenna beams and the omni-directional antenna beam for receiving signals from the client station (12). The signals received via each scanned antenna beam are measured, and on of the antenna beams is selected based upon the measuring for communicating with the client station (12). The selected antenna beam is preferably a directional antenna beam. Once the directional antenna beam has been selected, there are several usage rules for exchanging data with the client station (12). The usage rules are directed to an active state of the access point (14), which includes a data transmission mode and a data reception mode.

Abstract translation: 接入点（14）在与客户站（12）通信的802.11无线通信网络（10）中操作，并且包括用于产生定向天线波束（20）和全向天线波束（22）的智能天线（16） ）。 天线转向算法（18）扫描定向天线波束和全向天线波束，用于从客户站（12）接收信号。 测量经由每个扫描天线波束接收的信号，并且基于与客户站（12）进行通信的测量来选择天线波束的导通。 所选择的天线波束优选地是定向天线波束。 一旦选择了定向天线波束，就有与用户台（12）交换数据的几种使用规则。 使用规则被引导到接入点（14）的活动状态，其包括数据传输模式和数据接收模式。
