摘要： This invention describes systems and methods for combining the Wireless Local Area Network (WLAN) infrastructure and Wireless Intrusion Prevention Systems (WIPS) by leveraging a common radio platform equipped with more than one WLAN radio and a unified management system. The invention provides all the benefits of the WLAN, without sacrificing the 24×7 dedicated security monitoring and performance troubleshooting available from an overlay WIPS system, while reducing the deployment cost and management complexity, by sharing a common hardware platform for the WLAN Access Point (AP) and WIPS sensor and leveraging an integrated management system.

摘要： In a wireless network having an access point and at least one wireless end device, the access point is operable to differentiate between normal communications and interference from another device in order to capture a sample of the interference, determine whether the interference originates from a known type of device, and prompt remedial actions such as moving communications to a distant channel, increasing transmission power, changing data rate, and packet fragmentation based on whether the interference originates from a known type of device. Interference pulse duration may be used to at least initially narrow the possible sources of interference. Pulse period may be employed to differentiate between interference sources which exhibit similar pulse duration. If pulse duration and period are not sufficient to identify the interference source then other characteristics may be examined, such as pulse waveform, roll off and period in relation to local power frequency. In the case of microwave interference it is generally best to move to a distant channel. Increased transmission power and packet fragmentation can be used to maintain communications while scanning for a new channel.

摘要： Migrating from a legacy spectrum allocation to a target spectrum allocation can be accomplished by adding new access points and, at a selected time, activating the new access points and deactivating the legacy access points with a remote network manager. Alternatively, the new access points can initially support legacy channels and at a selected time be reconfigured to support only the target channels. Alternatively, the new access points are initially activated in a mode which supports only a subset of the target channels and at a selected time reconfigured to support only the target channels. A remote network manager may be employed to remotely monitor, reconfigure, and trigger activation and deactivation of access points in support of the technique. New access points adapted to respond to inputs from the remote network manager further facilitate the invention. For example, the new access points may be remotely configurable to activate, deactivate, support a legacy spectrum or portions thereof, support a target spectrum or portions thereof, and provide traffic load and other data to the remote network manager.

摘要： A system and method for Access Point (AP) channel selection based upon a Channel Quality Index (CQI) is described. The Channel Quality Index (CQI) is a value which quantifies a transmission quality of a channel. The transmission quality is evaluated based on a combination of different types of measured interference in the channel. In one embodiment the different types of measured interference include co-channel congestion, adjacent channel interference and in-band interference. The CQI is a value derived from the measurements, and for example may be a sum of all of the measurements. Each AP of the present invention determines the CQI of potential transmission channels, and selects a channel for use which has the ‘best’ CQI; for example if the CQI is a sum of all measured interferences, the ‘best’ AP is the one with the lowest CQI

摘要： A port on a network device engages in auto-negotiation on a network link during a first operational state to select a transmission mode, either half duplex or full duplex. If half duplex operation is selected, the port commences half duplex operation in a second operational state. During the second operational state, the link is monitored for an error condition indicating that another network device attached to the link may not be operating in a half duplex mode. This error condition includes the occurrence of excessive collisions or late collisions. When the error condition is detected, the port commences full duplex operation in a third operational state, based on the presumption that device at the other end of the link may be configured for fixed full duplex operation. If proper operation ensues, the port remains configured for full duplex transmission. Because the presumption may be incorrect, the link is monitored during the third operational state for a second error condition indicating that transmissions by the network device may be interfering with transmissions by the other network device. Examples of the second error condition include excessive frame check sequence errors and an excessive number of abnormally truncated messages. If such a second error condition occurs, the port is disabled in a fourth operational state and the condition is reported to higher-level operating software. Repeated attempts at normal operation may follow, with further monitoring that may result in shutting down the port if normal operation cannot be achieved.

摘要： A port on a network device engages in auto-negotiation on a network link during a first operational state to select a transmission mode, either half duplex or full duplex. If half duplex operation is selected, the port commences half duplex operation in a second operational state. During the second operational state, the link is monitored for an error condition indicating that another network device attached to the link may not be operating in a half duplex manner. This error condition includes the occurrence of excessive collisions or late collisions. When the error condition is detected, the port commences full duplex operation in a third operational state, based on the presumption that device at the other end of the link may be configured for fixed full duplex operation. If proper operation ensues, the port remains configured for full duplex transmission. Because the presumption may be incorrect, the link is monitored during the third operational state for a second error condition indicating that transmissions by the network device may be interfering with transmissions by the other network device.

Repeated attempts at normal operation may follow, with further monitoring that may result in shutting down the port if normal operation cannot be achieved.
摘要翻译：网络设备上的端口在第一操作状态期间在网络链路上进行自动协商，以选择半双工或全双工的传输模式。如果选择了半双工操作，则端口在第二操作状态下开始半双工操作。在第二操作状态期间，监视该链路的错误状况，指示连接到链路的另一网络设备可能不以半双工方式操作。该错误状况包括发生过度碰撞或后期碰撞。当检测到错误条件时，端口在第三操作状态下开始全双工操作，基于假设链路另一端的设备可以被配置为固定全双工操作。如果正确操作，端口仍然配置为全双工传输。因为推测可能不正确，所以在第三操作状态期间监视链路是否存在第二错误状态，指示网络设备的传输可能会干扰其他网络设备的传输。第二错误条件的示例包括过多的帧校验序列错误和过多的异常截断的消息。如果发生这样的第二个错误条件，则在第四个操作状态下禁用端口，并将该条件报告给较高级别的操作软件。如果正常操作无法实现，可能会出现重复的正常操作尝试，进一步监控可能导致关闭端口。

摘要： A portable storage device has a storage peripheral interface connecting to a computer. An encrypted data storage is available to the computer connected to the interface. The encrypted data storage includes a first part accessible after an authentication. A controller has a first operation mode performing encryption and decryption of data of the first part after the authentication of a first combined credential. The encryption and the decryption rely on a cipher key derived from a second combined credential. The first combined credential and the second combined credential are derived from at least a computer signature of the computer connected to the interface and a user credential of a user of the computer connected to the portable storage device.
