    Abstract: 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.

    Abstract: Described herein are a computer-implemented method of determining a power plan/frequency plan combination assigning transmit frequency channels and transmit powers for a plurality of managed access points (APs) of a wireless network. Also described herein is a carrier medium carrying computer readable code configured to cause one or more processors of a processing system to implement the computer implemented method of determining a power plan/frequency plan combination. The method includes determining candidate power plans for the access points, including determining candidate transmit powers for the access points, determining a candidate frequency plan corresponding to each of the determined candidate power plans using a frequency plan determining method to determine a set of candidate power plan/frequency plan combinations, and rating each combination of a candidate power plan and candidate frequency plan according to an evaluation criterion, and selecting a preliminary power plan/frequency plan combination based on the rating. One embodiment of the method further includes determining a final power plan for the preliminary frequency plan of the preliminary power plan/frequency plan combination to obtain a final power plan/frequency plan combination.

    Abstract: 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.

    Abstract translation: 一种用于网络规划的技术，其包括用于通过网络分配过程来指导网络用户的接口，诸如基于其能力来定义客户端组。 在组之间分配无线局域网基础设施的部分，例如接入点。 当客户端尝试与接入点关联时，接入点确定客户端功能。 如果客户端被接入点支持，则接入点允许客户端将客户端关联并发送包含分配给该客户端的其他附近接入点的优先列表的消息，否则该接入点发送优先化的漫游列表 分配给客户端的客户端的附近接入点。 反馈由网络基础设施提供，使网络用户或网络能够根据反馈自动重新分配资源。
