Abstract (en)
[origin: WO2009068198A2] A device for wirelessly networking devices of automation technology comprises a signal path (52) for transmitting a high-frequency transmit signal which has a plurality of chronological signal packets. The device has a first and a second antenna (30, 32) and an antenna switch (54) that connects the signal path (52) optionally to the first or to the second antenna (30, 32). A control circuit (59) is adapted to use the chronological signal packets to produce a low-frequency switch signal for the antenna switch (44).
