摘要： A method and system for scanning in a wireless device having a wireless network interface card (NIC) is presented. The system has a scanning history table for storing scanning results and a scanning engine that adjusts the scanning period based upon a history of scanning results and commands the NIC to scan for available networks after the period has expired. The engine receives scan results from the NIC, stores the scan results in the scanning history table, determines a scanning period based upon a history of scan results, sets the scanning period, and commands the NIC to scan for available networks after the scanning period has expired. The engine is programmed to set the scanning period using an exponential function and to reset the scanning period to a default period if the scan results are different from a prior scan result or if a triggering event is received.

摘要： To reduce the power consumption of a wireless communication hardware device, power conservation scheduling algorithms can be implemented. Reoccurring events, including DTIM intervals and listen intervals can be scheduled as awake times. Similarly expected response intervals can be scheduled as awake times based on information, such as round trip time, that can be passed together with data to be transmitted. The wireless communication hardware device can be placed into a doze state unless it is transmitting data, or unless it is expecting a transmission during one of the scheduled awake times.

摘要： Computer-implemented methods for power management of network interface devices are disclosed. Such methods may include dividing a time period into a plurality of time slots, determining an amount of data received by the network interface device during a first of the time slots, and determining whether the amount of data received exceeds a predefined threshold. If the amount of data received exceeds the predefined threshold, then the network interface device is caused to be awake during a subsequent time slot. The network interface device is caused to go to sleep during the subsequent time slot unless the amount of data received exceeds the predefined threshold. A number of the time slots may be defined as wakeup time slots during which the network interface device is awake. The number of time slots during the time period in which one or more packets were received by the network interface device may be compared to the number of wakeup time slots during the time period. Based on the comparison, the number of wakeup time slots may be adjusted for a subsequent time period.
摘要翻译：公开了用于网络接口设备的电源管理的计算机实现的方法。这样的方法可以包括将时间段划分为多个时隙，确定网络接口设备在第一时隙期间接收的数据量，以及确定所接收的数据量是否超过预定阈值。如果接收到的数据量超过预定阈值，则在后续时隙中使网络接口设备唤醒。使网络接口设备在随后的时隙中进入休眠状态，除非接收到的数据量超过预定义的阈值。多个时隙可以被定义为网络接口设备唤醒期间的唤醒时隙。可以将网络接口设备接收到一个或多个分组的时间段内的时隙数与该时间段内的唤醒时隙数进行比较。基于该比较，可以随后的时间段调整唤醒时隙的数量。

摘要： An evaluation of supported rates of available wireless networks is performed and these supported rates are matched against supported rates of wireless connection hardware (e.g., a wireless network interface card) of a computer trying to connect to one of the wireless networks. If the wireless connection hardware of the computer supports the rates supported by a desired wireless network, the computer is able to connect to the wireless network. If the supported rates for the wireless network and the wireless network hardware of the computer do not match, the computer is not able to connect to the wireless network and the situation is handled accordingly, such as by presenting the computer an appropriate message or not permitting the computer to connect to the wireless network.

摘要： Described is a system and method for transporting interference-related control data and other information between nodes in a wireless network, using a control channel that is distinct from a content channel used to transport content. The control channel may be a different channel in the same unlicensed band as the content channel, a channel in a different unlicensed band, or a channel in a licensed band, and thereby not subject to the same interference-related problems that the unlicensed content channel may experience. As a result, management information for adjusting the content channel's communication parameters may still be communicated between the nodes, whereby mitigation actions may occur. For example, the content channel may be changed to another frequency, compression may be implemented or varied, and/or the data transfer rate may be varied. The control data can also be used to change the control channel's communication parameters.

摘要： A method and system for managing power consumption in a portable computing device having a network interface module is presented. A power management module receives inputs from other modules and determines when the network interface module is to be put in a doze state for a predetermined number of beacon intervals to conserve power consumption in the network interface module. The network interface module in a device that is associated with a network is put in the doze state after an event has occurred including when a scan has been performed, after a delayed sleep timer has expired, and after a beacon transmission has been completed and no traffic is buffered for the device. The delayed sleep time is set based on the estimated round trip time of a packet.

摘要： An architecture and methods for extending the depth of a WLAN to a four-level hierarchal access point structure including wireless access points. The wireless access points in the WLAN can be networked by scanning for a network, collecting one or more packets that identify the network from one or more access points, each packet including an address identifying an ancestry of the access points to an ancestral wired access point; and applying an access point selection algorithm to configure a parent access point. The architecture includes a scanning object configured to issue a scan request to a network interface and collect access point data; a selection object configured to filter and sort the collected access point data; an authentication state machine configured to perform authentication and validate; and an association state machine configured to compose a packet including hierarchical data indicative of access point ancestry to a conventional access point.
