Geographical web browser, methods, apparatus and systems

Abstract

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 wireless LANs, microcells, and other such local broadcast domains. A mobile unit communicates with a network server via an air interface that supports wireless packet data. The mobile unit receives a broadcast transmission from a local broadcast domain entity that uses a low power local wireless protocol. The transmission includes a data packet that includes an indication related to information content. A content-selective information filter then compares a content-based filter parameter with the indication in the packet and selectively passes information related to the packet when a match is identified. In response to the identified match, a user is notified and given the option to request the content to be coupled from the mobile unit to the network server.
