Abstract: In an example embodiment, an access point or wireless local area network controller programs an opaque cookie into a wireless client. The cookie carries association detail and current traffic information of the client. When the client roams to a new access point, the client presents the cookie to the new access point.

Abstract translation: 在示例实施例中，接入点或无线局域网控制器将不透明cookie编程到无线客户端中。 该cookie携带客户端的关联详细信息和当前交通信息。 当客户端漫游到新的接入点时，客户端将cookie呈现给新的接入点。

Abstract: The direction of movement of a wireless local area network client device, determined based on data generated by one or more sensors onboard the client device, is provided by the client device to its serving access point. Using the direction of movement information, a list is generated of neighbor access points that are likely to be in the path of travel of the client device. The list may be generated by the serving access point or another infrastructure device, e.g., a wireless network controller. The serving access point sends the list of neighbor access points to the client device to enable the client device to select an access point to roam to at the appropriate time.

Abstract translation: 根据客户端设备上的一个或多个传感器生成的数据确定的无线局域网客户端设备的移动方向由客户端设备提供给其服务接入点。 使用移动信息的方向，生成可能在客户端设备的行进路径中的邻居接入点的列表。 该列表可以由服务接入点或另一个基础设施设备（例如，无线网络控制器）生成。 服务接入点将邻居接入点列表发送到客户端设备，以使得客户端设备能够在适当的时间选择一个接入点漫游。

Abstract: In an example embodiment disclosed herein there is described a multi-radio device which comprises a first radio that first radio comprises a transmitter, and a second radio that second radio comprises a receiver that monitors a channel to obtain data representative of a predefined channel parameter. The second radio is operable to receive a signal from the first radio that indicates when the transmitter of the first radio is transmitting. The receiver of the second radio selectively excludes data representative of a predefined channel parameter based on whether the transmitter of the first radio is transmitting.

Abstract: In one embodiment, a method includes receiving at an access point, notification of a rogue device in a wireless network, transmitting a plurality of association requests to the rogue device from the access point, and for each of the association requests that is accepted, transmitting a message to maintain an association between the access point and the rogue device to prevent association of clients with the rogue device. An apparatus and logic are also disclosed herein.
