    • Briefly, in accordance with one or more embodiments, a device is capable of operating at a first bandwidth or a second bandwidth, and further capable of operating using a communication method intolerant to operation at the first bandwidth. If operation using a communication method intolerant to operation at the first bandwidth is desired, the device transmits an assertion of intolerance of operation at the first bandwidth to one or more devices on the network to cause the one or more devices on the network to switch operation at the second bandwidth.
    • 简而言之,根据一个或多个实施例,设备能够以第一带宽或第二带宽进行操作,并且还能够使用不允许在第一带宽上操作的通信方法进行操作。 如果期望使用不能以第一带宽进行操作的通信方法的操作,则设备向网络上的一个或多个设备发送对第一带宽的不允许的不允许的断言,以使网络上的一个或多个设备切换操作 在第二个带宽。

    • Embodiments of the invention describe a method and device for controlling a physical layer of a communication device to operate in one of three modes of communication. In a first mode, the device is able to demodulate frames of a Complimentary Code Keying (CCK) modulation type. In a second mode, the device is able to demodulate frames of an Orthogonal Frequency Division Multiplexing (OFDM) modulation type. In a third, autodetection mode, the device is able to automatically detect the modulation type of a received frame and to configure the communication device to demodulate the received frame according to the detected modulation type. Control of the physical layer may be based on criteria related to prior transmissions received or transmitted by the communication device.
    • 本发明的实施例描述了一种用于控制通信设备的物理层以在三种通信模式之一中操作的方法和设备。 在第一模式中,该装置能够解调免费码键控(CCK)调制类型的帧。 在第二模式中,该装置能够对正交频分复用(OFDM)调制类型的帧进行解调。 在第三种自动检测模式中,设备能够自动检测接收到的帧的调制类型,并根据检测到的调制类型配置通信设备对接收到的帧进行解调。 物理层的控制可以基于与由通信设备接收或发送的先前传输相关的标准。
