The method involves defining a hierarchy number (h) for the individual pooling stations, to indicate how many intermediate stations must be passed to reach the management station. The individual pooling stations are allocated a station identifier. Data sets to be transmitted are combined with the station identifier and the hierarchy number to form a data packet. The individual pooling stations are synchronised at intervals by synchronisation data packets output from the management station in the up direction. Radio transmission is performed in sequential time slot blocks, which are allocated respective hierarchy numbers. A respective time slot is provided for the individual pooling stations within the time slot block. |
