    • Electronic devices may be provided that contain wireless communications circuitry capable of supporting time division multiple access. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. Signal strength measurements may be gathered using the antennas and corresponding signal strength difference measurements may be computed to reflect which of the antennas is exhibiting superior performance. The signal strength measurements may be made by measuring receive power levels in a beacon channel during idle time slots while toggling its antennas in and out of use or by detecting for the presence of non-silent traffic channel frames or silence indicator description frames and measuring corresponding receive power levels while toggling its antennas in and out of use. Beacon-channel-based measurements and non-silent-frame-based measurements may be used for electronic devices with receive diversity by simultaneously receiving frames of interest using each of its antennas and making corresponding measurements in parallel.

    • Electronic devices are be provided that contain wireless communication circuitry. The wireless communication circuitry includes radio-frequency transceiver circuitry coupled to first and second antennas. An electronic device sends network access probe signals to a base station in a wireless network. If the base station responds with a corresponding acknowledgement, the electronic device and base station establish a wireless communication link such as a cellular telephone link. In response to failure to receive the acknowledgement signal from the base station, the electronic device increases the transmit power of a successive network access probe signal. The electronic device switchs between use of the first and second antennas when transmitting the network access probe signals. The electronic device alternates between the first and second antennas or uses other antenna usage patterns.

    • Electronic devices are be provided that contain wireless communications circuitry. The wireless communications circuitry includes radio-frequency transceiver circuitry coupled to multiple antennas. Signal strength measurements are gathered using the antennas and corresponding signal strength difference measurements are produced to reflect which of the antennas is exhibiting superior performing. The signal strength difference measurements are filtered using time-based averaging filters with different speeds. Corresponding filtered difference measurements are compared to antenna switching criteria such as antenna switching thresholds. An antenna switching threshold is adjusted in real time based on computations of how much variation is exhibited as a function of time between the difference measurements filtered using the filters of different speeds. In addition, information on device movement or other data may be used in making threshold adjustments.
    • 提供包含无线通信电路的电子设备。 无线通信电路包括耦合到多个天线的射频收发器电路。 使用天线收集信号强度测量值,产生相应的信号强度差测量结果,以反映哪些天线表现出优异的性能。 使用具有不同速度的基于时间的平均滤波器对信号强度差测量值进行滤波。 将相应的滤波差分测量与天线切换标准(例如天线切换阈值)进行比较。 基于使用不同速度的滤波器滤波的差分测量值作为时间的函数的变化量的计算,实时地调整天线切换阈值。 此外,关于设备移动或其他数据的信息可用于进行阈值调整。
