Abstract
A signal booster device comprises a first antenna for communicating with a mobile and a second antenna for communicating with a base station. A signal path connects the antennas to each other. The signal booster device comprises a downlink amplifier, an uplink amplifier and a first downlink power detector for detecting a downlink signal power. The signal booster device comprises a bypass line for directly electrically connecting the first antenna to the second antenna and a control unit configured to obtain a measurement value from the first downlink power detector. The control unit is configured to enable the bypass line if the measurement value of the downlink signal power oversteps a first limit value so that the signal booster device switches from normal operation mode into bypass mode. The downlink amplifier and the uplink amplifier are electrically disconnected from the respective first antenna and second antenna if the bypass line is enabled.
