4 Example Application

An example of a scheme for a combined data and ranging communication is described in Combining Ranging and Data Communication, and see Figure 2-4 for implementation in a demo software application. The demo code uses simplified calculations to mimic and implement the AES, RS and MAC coding operations. The user can find code implementations on the Internet (also as freeware) to replace these simplified calculations (consider the specific license agreements). The simplified calculations in the demo code do not provide the security levels of real coding algorithms but are used as a placeholder and to demonstrate the communication and distance calculation principle.
