A method of operation of a node for obtaining channel information in a wireless communication network is disclosed. The method includes receiving periodically, information related to channel assessment capability of plurality of nodes of the wireless communication network, maintaining a metric characterizing the channel assessment capability for each of the plurality of nodes based on the received channel assessment capability, selecting at least one node from the plurality of nodes by comparing the metric of each of the plurality of nodes, sending a request for channel information to the selected node and receiving channel information from the selected node.

Method for facilitating sharing of channel information in a wireless communication network

A system and method for estimating the position of wireless devices within a wireless communication network combines measured RF channel characteristics for the wireless device with one or more predicted performance lookup tables, each of which correlates an RF channel characteristic to some higher order network performance metric and/or a position within an environmental model. Measured RF channel characteristics for wireless devices are compared against the performance lookup tables to determine the sent of lookup tables that most closely match the measured RF channel characteristics. The positions within the environmental model corresponding to the selected set of matching lookup tables are identified as possible locations for the wireless device. The performance lookup tables are uniquely constructed by site-specific location, technology, wireless standard, and equipment types, and/or the current operating state of the communications network.

System, method, and apparatus for determining and using the position of wireless devices or infrastructure for wireless network enhancements

A system and method for analysis of a wireless communications network is disclosed. A map of a physical environment integrating communications hardware for implementing a wireless communications network is defined. Client service requirements and regions for the wireless communications network are defined. Mesh point constraints and mesh linkage constraints for the wireless communications network are defined. The communications hardware is placed on the map at initial locations. Whether at least one of the defined mesh point constraints and mesh linkage constraints have been met by at least one mesh link between communications hardware based upon the initial locations of the communications hardware in the communications network is calculated. In one embodiment, the at least one calculation is displayed as a visualization on the defined map.

Method and system for analysis and visualization of a wireless communications network

A computerized model provides a display of a physical environment in which a communications network is or will be installed. The communications network is comprised of several components, each of which are selected by the design engineer and which are represented in the display. Errors in the selection of certain selected components for the communications network are identified by their attributes or frequency characteristics as well as by their interconnection compatability for a particular design. The effects of changes in frequency on component performance are modeled and the results are displayed to the design engineer. A bill of materials is automatically checked for faults and generated for the design system and provided to the design engineer. For ease of design, the design engineer can cluster several different preferred components into component kits, and then select these component kits for use in the design or deployment process.
