Abstract
A method for transferring data signals between a primary station (10) and secondary stations (SL1 to SL5) in a master / slave wireless network, the method comprising the steps of dividing a secondary station into a plurality of categories (Z1, Z2). Has a primary station belonging to The primary station transmits a beacon signal that includes an indication of a plurality of categories of the object having data to be transferred. The secondary station operating based on the wake-up sequence receives the beacon signal and determines whether the received beacon signal has an indication of its category. If so, the secondary station sends a request containing an indication of its identity. The primary station checks if it has a data packet for the identified secondary station, and if so, sends the data packet, otherwise sends a negative acknowledgment. Secondary stations not participating in this message exchange can return to sleep mode, thus saving power.
