A method for wireless data transmission between a base station and a transponder is provided, in which data are transmitted between the base station and the transponder in the form of data packets that include a header section with at least one symbol for setting one or more transmission parameters and include at least one additional section. The transponder monitors, during the data transmission, to determine whether a time period between two successive symbol delimiters transmitted by the base station exceeds a maximum time, and if the maximum value is exceeded, a receiver unit of the transponder is reset. The maximum time can be determined in the transponder on the basis of the at least one symbol in the header section.
