Abstract

Communication between a terminal, such as a consumption meter, installed at a fixed location and a mobile data collector, by way of Wireless M-Bus, via a short-range radio receiver. Data from the terminal is forwarded to the data collector via a bidirectional WPAN interface. The terminal sends a message periodically and unprompted for the communication set-up and subsequently opens a reception window after a period of time. In response, a command or a command sequence is conveyed from the mobile data collector to the receiver and to the terminal in one or more reception windows. The receiver determines the reception time at which the message arrives at the receiver, and the receiver stipulates the time at which the command or command sequence is transmitted onward to the terminal, so that the command or command sequence is received by the terminal within one reception window or multiple reception windows.
