摘要： In a wireless LAN (WLAN), methods, apparatuses and systems directed to facilitating configuration of a wireless network is provided. According to one implementation of the present invention, sensors are used to collect data associated with locations and other properties of access points of the wireless network. The collected data can then be used to assist in automatically configuring one or more aspects of the wireless network. In some implementations, the collected data can be used to dynamically re-configure the wireless network in real time. According to another implementation of the present invention, location computation mechanisms are used to collect data associated with the location of one or more wireless clients, and the data is used to dynamically adjust one or more radio frequency (RF) coverage maps in real time. The revised RF coverage maps can then be used to re-configure one or more operational parameters of the wireless network. Implementations of the present invention provide many advantages, such as automating the configuration of the wireless network in real time and facilitating network management decisions.

摘要： Techniques are provided for selecting channels for a wider bandwidth operation mode of a wireless network, such as wireless network that operates in accordance with the IEEE 802.11n amendment. Alignments of so-called primary and secondary channels are selected to mitigate interference. Interfering sources, such as other transceivers or external interferers, or the energy from their transmissions, are identified and channels are selected. The selected channels are analyzed to determine whether primary-secondary channel assignments for the selected channels are feasible.

摘要： A search algorithm to find a globally optimal radio plan for a wireless network, including assignments of frequency and transmission power to multiple access points. Two different evaluation metrics are used in order to provide an optimal solution in a reasonable time period. Frequency searches are performed using a special rapid evaluation metric. Transmission powers are selected using a more refined metric that estimates data throughput. The search results are deterministic and execution time is also substantially deterministic.

摘要： Systems and methods for evaluating wireless network quality. A metric provided by embodiments of the present invention relies on information that is relatively easy to collect, can be very efficiently computed, and yet provides a realistic estimate of likely wireless network performance. In one implementation, the input includes path loss data and access point transmitter power level and frequency settings. A capacity indicator is computed for each client and each access point. A data rate indicator is computed for each client location. The traffic load is computed for each access point. Based on these computed indicators, a bidirectional client throughput can be computed for each client and a combined metric can be determined for the network as a whole.

摘要： In an example embodiment, a time of arrival circuit coupled to a wireless transceiver configured to determine a time of arrival of a wireless signal. The time of arrival circuit is operative to perform a coarse-scale frequency domain correlation of the actual samples with a predetermined ideal sample. The time of arrival circuit determines a maximum coarse correlation coefficient. The time delay circuit is operative to determine a plurality of fine correlation coefficients by interpolating around the peak coarse correlation coefficient. The time of arrival circuit determines a maximum correlation coefficient from the plurality of fine correlation coefficients and a time delay associated with the maximum correlation coefficient, the time of arrival is based on the time delay associated with the maximum correlation coefficient.

摘要： A technique for network planning that includes an interface for guiding a network user through the network allocation process, such as defining groups of clients based on their capabilities. Portions of the wireless local area network infrastructure, e.g., access points, are allocated among the groups. When a client attempts to associate with an access point, the access point determines the client capabilities. If the client is supported by the access point, the access point allows the client to associate and sends the client a message that contains a prioritized list of other nearby access points allocated to service that client, otherwise the access point sends a prioritized roaming list of nearby access points to the client that are allocated to serve that type of client. Feedback is provided by the network infrastructure enabling a network user or the network to automatically reallocate resources based on the feedback.
