A geographical web browser allows a user to navigate a network application such as the Word Wide Web by physically navigating in geographical coordinates and roaming through coverage areas of cellular base stations, wireless LANs, microcells, and other such broadcast domains. A mobile unit receives unsolicited push messages in a local hotspot area. A packet filter filters local hotspot push messages to see whether they coincide with the user's preferences. In some embodiments, the push message is used to notify the user that information is available for download, and in other embodiments the push message or pushed packet sequence provides the content directly to the user.
