Abstract
The invention relates to a method for operating an RFID network consisting of a number of read-write stations (, N-N), for which a reader service signal () is modulated onto a read-write signal that is required to process a number of electronic labels (). According to the invention, the following steps are carried out: at least one read-write station (, N-N) is entrusted with the function of a master () that has stored a network structure () comprising structure data and a co-ordination plan containing co-ordination data; the master or masters transmit(s) () at least corresponding data for an organized synchronous network operation to the read-write stations (, N-N) periodically and/or on demand, so that the read-write stations (, N-N) do not interfere with one another during the read-write operation. This is achieved using a number of time slots () and a number of frequency channels (), a service frequency channel (reader service channel, RSK) and/or a service time slot (reader service time, RST) being available and used to synchronize and modify the structure and co-ordination data between the master () and the read-write stations (, N-N).
