A biomass fractionator and method are described for inputting ground biomass and outputting several vapor streams of bio-intermediate compounds along with syngas and biochar. The transmission device is also provided with a preamble adder which adds, to the transmission signals, respective preamble signals assigned in order of the transmission rates and used for estimation of channel responses at the wireless reception device. In the event of a connection error, the defective connection is deactivated. The first-agent baseline synchronization point may be associated with a first-agent baseline synchronization time of a first-agent synchronization between the first storage agent and the third storage agent that occurred before the second-agent synchronization time.
