    • Methods and systems for powering-off a wireless communication device from a linked device are provided. A device can transmit a wireless communication signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more wireless communication networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a wireless communication network through a single device.
    • 提供了用于从链接的设备断电无线通信设备的方法和系统。 设备可以向链接的设备发送无线通信信号,以指示链接的设备断电。 以这种方式,用户只需手动关闭一个设备,导致所有链接的设备都关闭电源。 该过程可以由用户通过与要关闭的设备直接链接的设备或通过一个或多个无线通信网络与要断电的设备间接连接的设备来发起。 当存在一组预定条件时,该过程也可以由设备自动启动。 一旦指示这样做,设备可以启动预定的断电过程,其可以涉及终止任何正在进行的功能并且关闭各种子系统。 根据本发明,用户可以通过单个设备发起无线通信网络上所有设备的断电。

    • An analog front-end (AFE) for a communications device includes a low-power frequency synthesizer with reduced footprint. The AFE includes a first frequency synthesizer and a second frequency synthesizer. The first frequency synthesizer is coupled to a transmit (TX) chain and to a receive (RX) chain of the AFE. The first frequency synthesizer is to generate a first local oscillator (LO) signal for transmitting or receiving carrier signals when the device is in a normal operating mode. The second frequency synthesizer is coupled to the RX chain and shares one or more components of the TX chain. The second frequency synthesizer is to utilize the one or more shared components to generate a second LO signal for receiving carrier signals when the device operates in a low-power mode. For example, the one or more shared components may include a voltage source and/or one or more inductors.
    • 用于通信设备的模拟前端(AFE)包括具有减小占位面积的低功率频率合成器。 AFE包括第一频率合成器和第二频率合成器。 第一个频率合成器耦合到AFE的发送(TX)链和接收(RX)链。 当第一频率合成器处于正常操作模式时,产生用于发送或接收载波信号的第一本地振荡器(LO)信号。 第二频率合成器耦合到RX链并共享TX链的一个或多个组件。 第二频率合成器是利用一个或多个共享分量来产生第二LO信号,用于在设备以低功率模式工作时接收载波信号。 例如,一个或多个共享组件可以包括电压源和/或一个或多个电感器。
