Method of wireless communication between a base station and a transponder
Abstract
The invention relates to a method for wireless data transmission between a base station (BS) and a, in particular passive, transponder (TR), in which data packets to be transmitted (DP) are modulated onto electromagnetic carrier waves and the data packets (DP) have a header with at least a symbol and at least one other section. According to the invention, the duration of at least one symbol in the header section is determined in the transponder (TR) and a parameter (f, I) determining the coding and / or decoding mode is set as a function of the determined time duration. Use eg for transponder-based identification systems and remote sensors.
