    • A method of optimizing the wireless power and signal integrity between an access point and multiple wireless clients includes an algorithm running in the access point that detects the downlink bandwidth and signal strength to a client device. Using this information, the wireless parameters of the access point can be adjusted to reach an optimal downlink power and signal condition. Uplink bandwidth and signal strength control to the access point is performed at each of the client devices using signal strength information provided by the access point. This achieves a dynamic balance with the adjustment of both the access point and the individual wireless client devices for transmit power control and signal integrity in a closed loop manner. The access point can perform the same dynamic balance while supporting multiple client devices operating in multiple frequency bands.
    • 优化接入点和多个无线客户端之间的无线功率和信号完整性的方法包括在接入点中运行的算法,其检测到客户端设备的下行链路带宽和信号强度。 使用该信息,可以调整接入点的无线参数以达到最佳下行链路功率和信号状态。 使用由接入点提供的信号强度信息,在每个客户端设备处对接入点的上行链路带宽和信号强度进行控制。 这实现了与接入点和各个无线客户端设备的调整的动态平衡,用于以闭环方式发送功率控制和信号完整性。 接入点可以执行相同的动态平衡,同时支持在多个频带中工作的多个客户端设备。

    • A power converter system (100) comprises a power converter (102), an analyzing circuit (114) and a power converter controller (110). The power converter (102) receives a mains voltage (108) and provides power (104) to a signal processing circuit (106). The power converter (102) is configured for operating in either a first mode wherein the power converter (102) is able to supply a first power level, or in a second mode wherein the power converter (102) is able to supply a second power level. The second power level exceeds the first power level. The signal processing circuit (106) processes a signal (116) in a normal operational mode. The analyzing circuit (114) analyzes the signal (116). The analyzing circuit (114) generates a power signal (112) that indicates a power consumption of the signal processing circuit (106) in normal operation. The power converter controller (110) receives the power signal (112) and controls the power converter (102) to operate in the first mode or in the second mode. The power converter (102) is controlled to operate in the first mode only when the power signal (112) indicates that the power consumption of the signal processing circuit (106) is below the first power level.
