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： Methods, apparatuses and systems directed to facilitating increased throughput in wireless mesh networks. Generally, according to one implementation of the present invention, routing nodes in a wireless mesh network combine metrics corresponding to the link and network layers to select a route to a root node in the wireless mesh network. In one implementation, for each neighbor, a given routing node computes a routing metric, which is based on the computed route cost and hop count, and selects a preferred neighbor as the parent routing node based on the best routing metric.

摘要： In one embodiment, a method for adjusting a radio-frequency coverage map. The method includes receiving calibration data comprising observed received signal strength values at one or more calibration points corresponding to a radio frequency transmitter, and identifying an applicable coverage map, where the coverage map provides, for the radio frequency transmitter, estimated received signal strength values at one or more locations. The method also includes determining one or more offset values at the one or more calibration points, where an offset value is based on a difference between an observed received signal strength value and an estimated received signal strength value at a given calibration point. The method also includes adjusting one or more estimated received signal strength values at one or more location bins of the coverage map based on a distance from the one or more calibration points and the one or more offset values.
