Method, transponder and system for rapid data exchange

摘要

The method involves transmitting a telegram comprising a command (K) and a data sequence (D) by a base station (B). The telegram is received and evaluated by a backscatter-based transponder (T). A code is provided to the transponder after receiving the command and before a complete reception of the telegram, and the code is transmitted to the base station. The code is detected by the base station, and parts of the telegram to be transmitted are encoded by the base station with the code. An independent claim is also included for a system for wirelessly transmitting data between a base station and a passive or backscatter-based transponder.
