    • 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 according 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 addressed 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.
