Radio stations in a radio communication system send messages from one radio station to another either directly or via one or several radio stations forwarding the messages by using radio resources. An opening is created in the tissue at the implantation site. The FEU receives a radio frequency signal, generates time-interleaved samples, an includes: a first array of first time-interleaved samplers, a second array of second time-interleaved samplers, and a third array of third time-interleaved samplers. The air blows out a passageway within the cigar so that the cigar will draw when smoked.
