    • A device previously configured as a registrar and that has established an independent ad-hoc network is automatically discovered by another device also previously configured as a registrar. To form an ad-hoc wireless network between these two devices, each device periodically enters a scanning mode to scan for and intercept beacons transmitted by the other device. Upon such interception, one of the devices becomes an enrollee in accordance with a predefined condition and in response to a user selected option. Subsequently, the enrollee modifies its beacons to include an attribute, such as the MAC address, associated with the other device. After intercepting the modified beacon, the remaining registrar prompts it user to decide whether to allow the enrollee to join the registrar's network. If the user responds affirmatively, a handshake is performed between the two devices and a subsequent attempt is made by the enrollee to join the registrar's network.
    • 先前配置为注册服务商并建立了独立专用网络的设备由之前配置为注册服务商的另一设备自动发现。 为了在这两个设备之间形成ad-hoc无线网络,每个设备周期性地进入扫描模式以扫描并拦截由另一个设备发送的信标。 在这样的监听之后,其中一个设备根据预定义的条件并响应于用户选择的选项而成为登记者。 随后,参与者修改其信标以包括与其他设备相关联的属性,例如MAC地址。 拦截修改后的信标后,剩余的注册服务商提示用户决定是否允许参与者加入注册服务商的网络。 如果用户作出肯定响应,则在两个设备之间执行握手,并且随后尝试登记者加入注册服务商的网络。

    • A method of configuring an ad-hoc wireless network between an authenticator and a plurality of wireless devices seeking authentication includes assigning a wireless device as the authenticator and receiving a first setup message transmitted from a first device seeking authentication to the authenticator and initiating a first handshake process between the authenticator and the first device seeking authentication. The method also includes receiving a second setup message transmitted from a second device seeking authentication to the authenticationn. The. second-setup-msssage is. received by the authenticator prior to completion of the first handshake process. The method further includes initiating a second handshake process between the authenticator and the second device seeking authentication. The second handshake process is initiated prior to completion of the first handshake process. Moreover, the method includes completing the first handshake process and completing the second handshake process.

    • A method selects a codebook for transmit beamforming. The method constructs an estimated channel matrix based on a codebook. selects a channel submatrix from the estimated channel matrix, calculates a selection matrix from the channel submatrix; and assigns a steering matrix based on the selection matrix. There may be multiple codebooks and the method may construct an estimated channel matrix, select a channel submatrix, and calculate a selection matrix for each of the codebooks, then select an optimal codebook. The steering matrix is assigned based on the optimal codebook. The steering matrix may be used in steering a transmitted packet. The method may also calculate a post-MIMO equalizer signal-to-noise ratio for a data stream, based on the estimated channel matrix and the selected codebook. A related system is also disclosed. Other embodiments are provided, and each of the embodiments described herein can be used alone or in combination with one another.
