The invention relates to a communication device (8) for wirelessly communicating with a sensor (4). The communication device (8) comprises a receiver for receiving signals, an amplifier for amplifying the received signals, a transmitter for transmitting signals, and a controller. The controller is operable in a first mode in which signal strength values are determined over time, which are indicative of a strength of an amplified received signal, and in a second mode in which signal transmission and reception are controlled based on the determined signal strength values. The determined signal strength values can be indicative of, for instance, a saturation of the amplifier caused by a transmission operation of another, neighboring communication device such that, by considering the determined signal strength values, the transmission carried out by the communication device (8) can be synchronized with the corresponding operation of the neighboring communication device. This can lead to reduced disturbances.
