    • A wireless access point is equipped with both an omnidirectional antenna and a directable antenna that can be selectively directed to any of a plurality of directional spaces overlapping the network space served by the omnidirectional antenna. The directable antenna is directed to an optimal directional space for a client when the access point is communicating with the client at a high data rate. The access point can intermittently exchange information with other clients using the omnidirectional antenna. The omnidirectional antenna enables broadcast signals to be transmitted to any client in the entire network space, but at a lower data rate. A preferred data rate and an optimal client directional space are re-determined periodically or as necessary based on parameters such as the data rate, signal strength, and rate of success in communicating data.
    • 无线接入点配备有全向天线和可定向天线,其可以被选择性地定向到与由全向天线所服务的网络空间重叠的多个定向空间中的任何一个。 当接入点以高数据速率与客户端通信时,可定向天线被定向到客户端的最佳定向空间。 接入点可以使用全向天线间歇性地与其他客户端交换信息。 全向天线能够将广播信号传输到整个网络空间中的任何客户端,但数据速率较低。 根据诸如数据速率,信号强度和通信数据成功率的参数,周期性地或根据需要重新确定优选数据速率和最佳客户机定向空间。
