Abstract
An arrangement for wirelessly networking sensors, actuators and at least one shared control unit in automation technology, has a first connection point for receiving an RF transmit signal from an RF transmitter and for providing an RF receive signal from an antenna. The arrangement has a second connection point, which leads to the antenna, and a signal coupler, arranged between the first connection point and the second connection point. The signal coupler transmits the RF transmit signal from the first connection point to the antenna, and transmits the RF receive signal from the antenna to the first connection point. The signal coupler has a variable coupling attenuation with a low first attenuation factor and at least one higher second attenuation factor. The signal coupler transmits the RF receive signal using the low first attenuation factor and transmits the RF transmit signal using the higher second attenuation factor.
