摘要： In a fixed channel wireless network system with a limited number of channels, assignment of the fixed channels between remote client elements and access elements is made systematically according to a set of criteria accounting for network loading and interference, then channel assignments are dynamically updated according to a priority to maintain optimal network performance with changing conditions of load and interference. The channel utilization problem is address at a system level rather than at a local level by treating the system as a three dimensional color mapping problem. All noise is treated as having a source in virtual access elements with an appropriate performance metric. The performance metric is used to select a channel set that minimize chances of interference and maximize user performance. Specifically, there are several parameter matrices which are managed and updated by a central resource management element, namely signal strength between elements, interference, and load. These matrices are used to find the optimal channel assignments for a predetermined limited set of assignable channels. In one implementation, the channel assignment methodology takes into account the interference associated with access elements operating on a selected channel, as well as the interference or energy that spills over (or is otherwise observable) on physical channels adjacent to the selected channel.

摘要： Methods, apparatuses and systems facilitating containment of the effects of rogue or unauthorized access points on wireless computer network environments. Embodiments of the present invention support one to a plurality of rogue containment methodologies. A first rogue containment type involves identification of the physical connection of the rogue access point to the wired network infrastructure and, thus, allows for disabling of that physical connection to contain the rogue access point. Other rogue containment methods involve wireless techniques for containing the effect of rogue access points. As discussed below, the rogue containment functionality described herein can be applied to a wide variety of wireless network system architectures.
