Many applications already take advantage of this kind of technology. Here are a few examples of how it is used.
1. Client’s phone has “History Alive” app installed. Application contains GPS location tracking. In this case the user is on the Washington Mall facing the Lincoln Memorial. The application uses GPS to establish precise location. Application is further enabled with visual anilization capabilities so it can key augmented reality projection of Martin Luther King to the top steps of the Lincoln Memorial.
2. “History Alive” app sends open session request to server.
3. Layer 6 adds user authentication to message.
4. Information is further encoded by the presentation layer so it is “device independant.” The message is then sent by to the transmission layer using TCP/IP (layers 3 and 4).
6. The message travels through the air to the cell tower wher it is passed through to ground cable and on to a WAN. A pathway is established to get the message to the final server.
7. Server receives the message and passes the requested video file back along the passtha to the clinet.
