    摘要： A client device detects when it roams between subnets and signals to a device in the subnet being entered. The client may detect roaming by monitoring subnet identifiers included in beacon signals transmitted by access points. When the client detects a beacon with a new subnet identifier and at the same time no longer detects a beacon with the original subnet identifier then roaming is indicated. When roaming is indicated the client responds by setting a tag, such as an IEEE 802.1q VLAN tag, in packets transmitted by the client. The tagged packets provide an indication to devices in the new subnet that the client has roamed into that new subnet. Devices in the new subnet, such as access points and switches, recognize the tagged packets and establish a path to the original subnet in response. For example, the tagged packets transmitted by the client may be encapsulated pursuant to a Layer 3 protocol and tunneled from a switch associated with the subnet being entered to a switch in the original subnet. If the client roams to other subnets the path is established from the new subnet to the original subnet, rather than an intermediate subnet.

    摘要翻译： 客户端设备检测在子网之间漫游以及正在输入的子网中的设备的信号。 客户端可以通过监视由接入点发送的信标信号中包含的子网标识来检测漫游。 当客户端检测到具有新子网标识符的信标，并且同时不再检测到具有原始子网标识符的信标时，指示漫游。 当漫游被指示时，客户端通过在客户端发送的分组中设置诸如IEEE 802.1q VLAN标签的标签来进行响应。 标记的数据包为客户端漫游到该新子网中的新子网中的设备提供指示。 新子网中的设备（如接入点和交换机）会识别已标记的数据包，并建立到原始子网的路径。 例如，由客户端发送的标记的分组可以根据第3层协议进行封装，并且从与所输入的子网相关联的交换机隧道传送到原始子网中的交换机。 如果客户端漫游到其他子网，则路径将从新子网建立到原始子网，而不是中间子网。

    摘要： A system and method for securing communications in a wireless network includes the steps of authenticating members of the wireless network, generating a member private key to be used by the members of the wireless network, and distributing the member private key to each of the members of the wireless network. A member is authenticated based on the ability of the member to be physically proximate to at least one other member of the wireless network at a given instant. The member private key is generated by one of the members, hereinafter referred to as a master member, in response to a changing value stored at the one of the members. The member private key is then securely distributed to each of the members in the WLAN network.

    摘要： The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
