1. A signal booster device for amplifying signals in a wireless communication network, comprising:

  • at least one first antenna for communicating with a mobile and at least one second antenna for communicating with a base station,the signal booster device providing a signal path for electrically connecting the at least one first antenna to the at least one second antenna for transmitting uplink and downlink signals,the signal path being split up at least partly into a first downlink signal path and into a first uplink signal path,at least one downlink amplifier for amplifying a downlink signal and at least one uplink amplifier for amplifying an uplink signal,the at least one downlink amplifier being arranged in the first downlink signal path, the at least one uplink amplifier being arranged in the first uplink signal path,at least one first downlink power detector for detecting a downlink signal power,a bypass line for directly electrically connecting the at least one first antenna to the at least one second antenna,a control unit configured to obtain a measurement value from the at least one first downlink power detector,the control unit being configured to enable the bypass line if the measurement value of the downlink signal power of the at least one first downlink power detector oversteps a first limit value so that the signal booster device switches from normal operation mode into bypass mode,the at least one downlink amplifier and the at least one uplink amplifier being electrically disconnected from the respective at least one first antenna and at least one second antenna if the bypass line is enabled.
