Abstract
A cellular phone network provides location-based information to a user of a cellular phone. The cellular phone network includes a plurality of antennas coupled to at least one server. The server is coupled to a database. Stored on the database is a plurality of location-based information that is indexed to the plurality of antennas. The cellular phone transmits communication signals to one of the antennas. A phone call is established between the server and the user, and the server receives an identification of the antenna that the user transmits to. The server then queries the database and retrieves information local to the user. This information is then presented to the user in the form of menus.
