Abstract: A server has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to collect scan lists from client devices. Each scan list specifies a WiFi access point identifier collected by a client device and geographic coordinates of the client device when the WiFi access point identifier was collected. A cluster of geographic coordinates is formed around a designated WiFi access point. A centroid within the cluster is identified. The location of the centroid is ascribed as the geographic position of the designated WiFi access point. A client device is advised when the designated WiFi access point is a known mobile WiFi access point to facilitate connection between the client device and the known mobile WiFi access point.

Abstract: A server has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to collect scan lists from client devices, where each scan list specifies a Wi-Fi access point identifier collected by a client device and geographic coordinates of the client device when the Wi-Fi access point identifier was collected. A cluster of geographic coordinates around a designated Wi-Fi access point is formed. A centroid within the cluster is identified. The location of the centroid is ascribed the geographic position of the designated Wi-Fi access point. The geographic position of the designated Wi-Fi access point is added to a Wi-Fi access point location database. A Wi-Fi tag scan list is processed to form a tag path listing known geographic locations of Wi-Fi access points observed by the Wi-Fi tag. The tag path is supplied in response to a request.

Abstract: A mechanism for supplying a stream of data to a browser is provided. The browser periodically refreshes a frame document, transmitting a request for the frame document to an HTTP server. When a network element receives a request from a browser for a frame document, it generates a new frame document, and supplies it to the browser. The new version of the frame document may include new definitions for functions, that, as redefined, reflect the current status of a network element. The updates may be retrieved by invoking functions.
