Abstract
A scheme is provided for distributing reference geographical locations on a network. Geolocation information is integrated or associated with one or more network infrastructure devices to permit them to serve as reference points for the rest of the network. A reference geographical location associated with a network infrastructure device may be broadcast by the network infrastructure device over a network. Alternatively, other network devices may request reference geographical location from a network infrastructure device or obtain it from a network-accessible database that stores such geolocation information. Other network devices can then use the one or more reference geographical locations to determine their own geographical location. By allowing existing network devices to take advantage of the geolocation capability of its “neighboring” network devices, this scheme provides a convenient way to deliver geolocation to many network devices.
