    • 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。

    • An accessory is provided for use with an existing antenna on a wireless device to improve directionality and/or signal strength. The accessory includes a conductive surface that is coupled to the existing antenna using a clip disposed on an arm that supports the reflector. The conductive surface is disposed at a quarter wavelength spacing from the existing antenna. Alternatively, the reflective surface may be made sufficiently large to reflect received wireless signals in regard to a plurality of existing antennas that are spaced apart, e.g., internal and external antennas. The reflector can optionally be curved to achieve a desired directional characteristic for the wireless signals reflected by the accessory. Also, a director can be included on the accessory to provide improved gain and directionality for the wireless signals, relative to the existing antenna system.
    • 提供附件用于与无线设备上的现有天线一起使用,以改善方向性和/或信号强度。 附件包括使用设置在支撑反射器的臂上的夹子耦合到现有天线的导电表面。 导电表面设置在与现有天线四分之一波长间隔处。 或者,可以使反射表面足够大以相对于间隔开的多个现有天线(例如内部和外部天线)反射接收的无线信号。 反射器可以可选地弯曲以实现由附件反射的无线信号的期望的方向特性。 此外,相对于现有的天线系统,可以在附件上包括导演以为无线信号提供改善的增益和方向性。
