20080267145 | Methods and Apparatus for Managing Wireless Networks Using Geographical-Level and Site-Level Visualization - A WLAN system and method enables network modeling and management through an easy-to-use user interface. A console coupled to the WLAN is configured to display a first set of graphical entities representing locations of the multiple sites in a geographical view, and display a second set of graphical entities in a site view representing a subset of the components selected in response to user input. An XML format may be used to display the various views on a browser operating within the console. | 10-30-2008 |
20080288432 | Device and Method of Fixing Wireless Network Problems - A method is used to fix wireless network problems. The method comprises receiving at least one parameter relating to a wireless network. The method comprises comparing the at least one parameter with a database of problem identities. Each problem identity has a set of criteria. The at least one parameter relates to the set of criteria. The method comprises determining at least one problem with the wireless network based on the comparison of the at least one parameter with the problem identities. | 11-20-2008 |
20090005063 | METHODS AND APPARATUS FOR IMPROVED LOCATIONING IN A WIRELESS NETWORK - Methods and systems are provided for determining the location of a first wireless device (e.g., a mobile unit) within a wireless network comprising a second wireless device (e.g., an access point). The method includes determining a signal strength contour associated with RF communication between the access point and the mobile unit, and adding a correction factor to the signal strength contour to produce a corrected signal strength contour, wherein the correction factor includes the sums of the differences between the transmit power and the antenna gain associated with the mobile unit and the access point. In an alternate scheme involving stored fingerprint data, a correction factor is introduced based on the differences between antenna gains and transmit power associated with the mobile unit under consideration and the mobile unit used for generating the fingerprint data. The systems and methods disclosed herein are applicable, for example, to networks operating in accordance with 802.11, RFID, WiMax, WAN, Bluetooth, Zigbee, UWB, and the like. | 01-01-2009 |
20090005064 | METHODS AND APPARATUS FOR LOCATIONING IN A WIRELESS NETWORK USING STATISTICAL WEIGHTING - Methods and systems are provided for determining the location of a first wireless device (e.g., a mobile unit) within a wireless network comprising a plurality of second wireless devices (e.g., access points). The method includes identifying an overlap area corresponding to the intersection of RF ranges for the one or more second wireless devices then computing a set of signal strength values, each associated with a measure of RF signal strength (e.g., RSSI) received by the plurality of second wireless devices from the first wireless device. A decision metric is evaluated for a plurality of locations within the overlap area based on the set of signal strength values. The location of the first wireless device is determined by selecting, from the plurality of locations, a location having the optimum value of the decision metric within the overlap area. The decision metric may utilize a minimum mean square error (MMSE) calculation. A weighting function may be used to remove redundant or weak signal strength values. The systems and methods are applicable, for example, to networks operating in accordance with 802.11, RFID, WiMax, WAN, Bluetooth, Zigbee, UWB, and the like. | 01-01-2009 |
20090043666 | GENERATION OF WIRELESS NETWORK PLANNING REPORTS WITH SKU AND PRICING DATA - A wireless network architecture planning system and related operating methods are disclosed herein. The planning system generates a report for a recommended wireless network architecture for a proposed floor plan, where the report contains product identifier codes (e.g., SKUs) for wireless infrastructure components and related accessories. An embodiment of the planning system executes a computer-implemented method that receives floor plan data corresponding to the site, produces a proposed wireless network architecture for the site, obtains product identifier codes corresponding to wireless infrastructure components needed to deploy the recommended wireless network architecture, and generates a report that lists the product identifier codes. | 02-12-2009 |
20090063121 | OPTIMIZATION OF DISPLAYED RF COVERAGE - A method for optimizing RF coverage includes dividing a floor plan according to a plurality of grids. Radio frequency coverage for each of the plurality of grids is calculated to render a plurality of coverages. First data representative of the plurality of coverage grids is provided to a client. Second data representative of an incremental change in radio frequency coverage for a first grid of the plurality of grids is provided to the client. | 03-05-2009 |
20090063525 | OPTIMIZED RF COVERAGE USING AJAX AND SVG - A method for displaying RF coverage information includes providing formatting data for displaying the radio frequency coverage information on a client. The formatting data is executed on the client. First radio frequency coverage raw data is provided to the client. The first radio frequency coverage raw data is utilized by the formatting data to construct an overall radio frequency coverage representation of a site. Subject to a subsequent request from the client, second radio frequency coverage raw data representative of radio frequency coverage is provided for a portion of the site. The second radio frequency coverage raw data is utilized by the formatting data on a supplemental basis. | 03-05-2009 |
