    • Methods for modifying a central frequency of a channel following a change in channel width between wireless devices are disclosed. The station desiring a channel width change notifies the AP and enters a constructive power management mode, which keeps the AP from sending frames to the station. This enables the station to move the central frequency without concern of data loss, then restores itself to a full-power state. Or, the station communicates the desire to switch channel modes after receiving a beacon frame from the AP, then switches the central frequency of the channel during a subsequent beacon, or during some predetermined time period prior to the subsequent beacon. While the central frequency is being changed, the station does not miss a frame intended to be communicated to the station.
    • 公开了在无线设备之间的信道宽度的变化之后修改信道的中心频率的方法。 希望通道宽度变化的站点通知AP,并进入建设性的电源管理模式,保持AP不发送帧到站。 这使得站能够移动中心频率而不考虑数据丢失,然后将其自身恢复到全功率状态。 或者,站点在从AP接收到信标帧之后传送切换信道模式的愿望,然后在随后的信标期间或在随后的信标之前的某个预定时间段期间切换信道的中心频率。 当中心频率发生变化时,车站不会错过要传送到车站的帧。

    • In some embodiments, a method for mitigating interference between wireless networks is disclosed. A network communications controller, such as a piconet controller that is new to an area, can monitor for and receive inter-network transmission from adjacent networks and the controller can monitor the received transmission and detect a synchronization parameter of the adjacent networks. The parameter can be an inter-network synchronization beacon that is transmitter on a narrowband channel. The controller can select an unoccupied narrowband channel to transmit inter-network synchronization information and the selected an unoccupied wideband channel to conduct intra-network transmissions. The wideband channel can be associated with the narrowband channel. Other embodiments are also disclosed.
    • 在一些实施例中,公开了一种用于减轻无线网络之间的干扰的方法。 网络通信控制器,例如新的区域的微微网控制器可以监视和接收来自相邻网络的网络间传输,并且控制器可以监视所接收的传输并检测相邻网络的同步参数。 该参数可以是作为窄带信道上的发射机的网间同步信标。 控制器可以选择未被占用的窄带信道来发送网络间同步信息,并且选择未占用的宽带信道来进行网内传输。 宽带信道可以与窄带信道相关联。 还公开了其他实施例。
