    • Systems and methodologies are described that facilitate mitigating a hidden node condition in a wireless mesh network wherein nodes utilize a request-to-send/clear-to-send (RTS/CTS) protocol in conjunction with an asynchronous hybrid automatic repeat request protocol. For instance, a node may contend for a set of subcarriers by sending an RTS signal over the desired subcarriers, and may receive a CTS signal over the contended subcarriers, wherein the CTS signal indicates which subcarriers the node may transmit data over. If another node has won the contention for a particular subcarrier, requesting node may adjust a power level at which it transmits an RTS or a data packet in order to permit the requesting node to utilize the subcarrier without interfering with the winning node.
    • 描述了有助于减轻无线网状网络中的隐藏节点条件的系统和方法,其中节点结合异步混合自动重复请求协议利用请求发送/清除发送(RTS / CTS)协议。 例如,节点可以通过在期望的子载波上发送RTS信号来竞争一组子载波,并且可以在竞争的子载波上接收CTS信号,其中CTS信号指示节点可以传送数据的哪些子载波。 如果另一个节点已经赢得了特定子载波的争用,则请求节点可以调整其发送RTS或数据分组的功率电平,以便允许请求节点利用子载波而不干扰获胜节点。

    • A wireless device and method of operating the device is disclosed. The wireless device is capable of communicating with multiple networks. The wireless device includes a transceiver configured to communicate with either one of two networks over a wireless medium. Each of the two networks has a different air interface protocol. The wireless device also includes a user interface having a keypad, display, and/or similar devices. A processor in the wireless device may be configured to select either one of the two networks for wireless communications with the transceiver. In at least one embodiment, the processor is configured to communicate with the transceiver using the air interface protocol for the selected network, and communicate with the user interface using a root protocol regardless of the network selected.
