<p>Private or closed networks configured to provide location or venue specific content or other localization information to mobile computing devices are based on periodic or other reassignments of network access point identifiers. Authorized network subscribers and applications can determine accurate mobile device location based on updated access point identifiers and RF signatures provided by mobile devices. Appropriate venue-based content or services can then be provided to mobile devices, while non-authorized subscribers and applications are hindered in their ability to determine mobile device location.</p> |
