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.
摘要翻译：在具有有限数量的信道的固定信道无线网络系统中，根据负责网络负载和干扰的一组标准系统地对远程客户端元件和接入单元之间的固定信道进行分配，然后，信道分配根据优先考虑负载和干扰条件下的最佳网络性能。信道利用问题是通过将系统视为三维颜色映射问题而在系统级而不是在本地级的地址。所有噪声被视为具有适当性能指标的虚拟访问元素中的源。性能指标用于选择最小化干扰机会并最大化用户性能的通道集。具体来说，存在由中央资源管理元件管理和更新的几个参数矩阵，即元件之间的信号强度，干扰和负载。这些矩阵用于找到预定有限的一组可分配信道的最佳信道分配。在一个实现中，信道分配方法考虑了与在所选信道上操作的接入单元相关联的干扰，以及在与所选择的信道相邻的物理信道上溢出（或以其它方式观察到）的干扰或能量。

摘要： Methods, apparatuses and systems facilitating location or containment 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. In some embodiments, the present invention provides methods, apparatuses and systems facilitating network location of rogue access points to determine whether one or more rogue containment methodologies should be applied. As discussed below, the rogue location and containment functionality described herein can be applied to a wide variety of wireless network system architectures.
