Method for operating an RFID network
The invention relates to a method for operating an RFID network consisting of a number of read-write stations (1, 2, 3, 11, N0-N17), for which a reader service signal (9, 105) is modulated onto a read-write signal that is required to process a number of electronic labels (6). According to the invent...

Zusammenfassung: | The invention relates to a method for operating an RFID network consisting of a number of read-write stations (1, 2, 3, 11, N0-N17), for which a reader service signal (9, 105) is modulated onto a read-write signal that is required to process a number of electronic labels (6). According to the invention, the following steps are carried out: at least one read-write station (1 2, 3, 11, N0-N17) is entrusted with the function of a master (100) that has stored a network structure (110) comprising structure data and a co-ordination plan containing co-ordination data; the master or masters transmit(s) (100) at least corresponding data for an organized synchronous network operation to the read-write stations (1, 2, 3, 11, N0-N17) periodically and/or on demand, so that the read-write stations (1, 2, 3, 11, N0-N17) do not interfere with one another during the read-write operation. This is achieved using a number of time slots (21, 31, 41) and a number of frequency channels (20, 30, 40), 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 (100) and the read-write stations (1, 2, 3, 11, N0-N17). |
