    • A method of providing a software patch to an electronic device. A device containing a software patch for an electronic device may be plugged to an electrical outlet. A plurality of electronic devices may be queried, over a power line through the electrical outlet, for identifying the electronic device requiring the software patch. As a result, the electronic device requiring the software patch may also identify the version of the firmware installed on the electronic device. Test signals may be sent over the power line to determine the signal quality of various multiple carriers for using OFDM scheme. Suitability of various sub-carriers for sending the software patch over the power line may be determined. Higher density modulation may be used for higher quality sub-carriers to send the software patch to the electronic device. An acknowledgment signal for receipt of the properly received authenticated software patch may be received.
    • 一种向电子设备提供软件补丁的方法。 包含用于电子设备的软件补丁的设备可以被插入电源插座。 可以通过电源插座在电力线上查询多个电子设备,用于识别需要软件补丁的电子设备。 因此,需要软件补丁的电子设备还可以识别安装在电子设备上的固件的版本。 可以通过电力线发送测试信号以确定用于使用OFDM方案的各种多载波的信号质量。 可以确定用于在电力线上发送软件补丁的各种子载体的适合性。 较高密度调制可用于较高质量的子载波以将软件补丁发送到电子设备。 可以接收用于接收正确接收的认证软件补丁的确认信号。
