Abstract (en)
[origin: EP1282094A2] The method involves switching on the receiver cyclically at defined time points, a substation (1,4,7) intending to send transmitting a preamble, a receiver (3,6,9) remaining on until the end of a preamble and switching off again if there is no preamble. The starting time of a data message is contained in the preamble. The receiver switches off after receiving the starting time and switches on again at this time.
